I'm new here. Just looked up some 350P threads. They were like 4 years old and didn't answer any of my questions. So, I'm starting this new 350P thread. I'll be asking a lot of questions. And please don't tell me to junk the 350 and go with a 400 or 455. There are LOTS of good 350P blocks that many guys can't even give away. So as the 400 and 455 blocks become harder to find, some will be left with the 350p as the only choice.I'll begin with just a few of my questions.(1) I've read that the 350P blocks from the last couple of years('76-'77?) with the casting # 500810 had the thin, weak, main webs, just like the "557" 400 blocks had. Does anybody know for sure ? Links ?(2) I've heard that many of the early blocks such as the '68-'69's had thicker cylinder walls than the later blocks. This would mean that they could take a .060 overbore or slightly more, providing there was no significant core shift. Does anybody know for sure ? Links ? I understand that you should always have the cylin der walls sonic checked for thickness before boring.(3) The old TRW L2339F forged pistons are long gone. Ace at PPR did sell a stock stroke and a stroker piston for the 350P. He's out now and nobody that I can find makes or sells a stock stroke forged 350P piston. Butler shows 2 stroker pistons, but they are custom Ross pieces which will cost in the $800 range total. A stock stroke piston would be the same price. So, do any of you guys know of a forged 350P piston any cheaper ??? BRC is the same price. Probe won't make one with under 4" bore. Icon don't make any custom pistons. And Wiseco is even higher than Ross. At least that's what they all told me this week over the phone.(4) I ran across this site, which says that they are the largest supplier of custom pistons in the country. So I called 'em. The old guy I talked to was not friendly at all. He said that he had been selling custom pistons for 59 years and had sold more than anybody. He told me that he could build me a set of 350P pistons with any pin size or location, including the pins and locks for $599 + freight, and the wait time would be about 3 weeks. Now $600 ain't cheap. But, it beats $800. The problem is, I haven't found anybody who ever bought any pistons from this guy. I haven't even got any responses from anybody saying they ever even heard of this business. So, is there anybody on this site who knows anything, either good or bad, about this business or their custom pistons ??? It's located in New Hampshire. The name is Flatlander Racing. Here's the link to the web site. http://www.flatlanderracing.com/pistons.html
Nobody knows anything about Flatlander Racing custom pistons, huh ??? OK, next question: Does anybody have or know where there is a set of NOS TRW L2339F forged 350P pistons, in either a .030, .040, or .060 oversize, for sale for a reasonable price.Here's another question. Ross and others will make custom 350P pistons for about $800 after you add the price of pins, pin fitting and freight. Do any of you guys know of any forged 350P pistons cheaper than this ?Yes, I know I asked that question in the last post. But I got no response. So, I'm asking again.There are plenty of cheap 350P blocks. So all we need is some decent forged pistons for a reasonable price. The 400 and 455 blocks are beginning to disappear, so we may need to use these 350P blocks. Right now we have the choice of cast pistons, $800 pistons or using some combination of modified forged 318 MOPAR pistons and BBC rods. If they are any good, the $600 Flatlander custom pistons will save almost $200. This still sounds kinda high just for a decent street build. But, since the blocks are considered junk by many, they should be real cheap or in some cases even free. I've read that some guys have tried to give 'em away and had no takers except scrap iron dealers.
Does anybody have any links to 350P high performance or racing engine builds ?
Info specific to 350 buildups is scarce, especially specific to the pistons you are asking about. The long and short of it is that currently we have little choice for pistons when it comes to 326/350 Pontiac V8's. I'm currently having my 1970 Tempest 350 rebuilt and I'm using Sealed Power cast 0.030" pistons. It all depends on your intended use of the engine. If you are building a warmed over stock engine like mine (Lunati cam, Edelbrock Performer, 4bbl, stock 11 heads) that will never see nitrous, forced induction or rpm in excess of 5500, then the cast pistons are fine. In fact there have been articles referencing the benefits of using a cast piston versus forged. They point out the quieter operation of cast due to tighter clearances, reduced cylinder wear (especially in engines that see only short trips), less cost considering that many musclecar engines came with cast pistons and they worked fine for many thousand miles and that many performance street engines don't actually need forged pistons. There are a few others on here who have built up 350's including our moderator Pontiacman8. Be patient, there may be responses coming but many members are busy and don't make it online as often as we'd like.Steve
A little help... 'cause we don't all have to learn the hard way!
helloflatlander pistons are fine. don't piss the old crusty guy off or you will be buying 800.00 pistons from someone else, lol.there are no links to 350 pontiac builds and none are necessary. it is just an engine. you will get all the info you want, need, and more right here, but it would be helpful to answer a few questions first.how much money do you have for engine, intake and carb?if you say 2000.00, you will not get helpful responses. serious power costs serious money.what are your rear gear ratio?are you willing to change them?the bigger the cam, the lower the gears must be.you need to run 91 octane or higher for a performance build.if you run e85 corn gas you can run higher compression than you can on 93 octane.do you want, mild, moderate or nasty idle?drag car, freeway flier or inbetween?tire warmer or tire roaster?if you run stock 350 heads then you will not gain much hp. you can port them to get a little more.eddy or afr aluminum heads are $1600.00 - $2000.00.
Not shootin fer the moon here. Just a nice 400hp build. All I need is some of the old heavy TRW L2339F forged pistons. But as we all know they are history. Ace, at PPR sold stock stroke and stroker 350P pistons. Now that he's gone the only forged 350P pistons I have found are custom. Butler advertises a 4.00 and a 4.25 350P stroker assembly. But the pistons are custom Ross. They are $675 + pins + plus freight. BRC are about the same price. Probe won't make 'em. Icon don't make custom pistons. Wiseco's are even higher than Ross. And I figure all the other big co like JE, Diamond, etc are all about the same. So, although the Flatlander pistons are $600, that's still $200 better than anything else I've found. The only reason I posted this is because I'd never heard of the Flatlander pistons and because I thought somebody else out there might wanna build a warm 350 with one of the many unused 350P blocks that many guys junk or try to give away. The 400 and 455 block supply can't last forever. You said there are no links to 350 builds and none are necessary. I am absolutely positive there was a 350HO build in an issue, a year or two back. But I couldn't call it up. That's all I was asking is how do you call up stuff in past issues of HPP. This forum is connected to HPP mag is it not ?By the way, where can you buy new, complete, alum heads for $1600 ? or, by the time you add bolts and freight, $2000 for that matter ? KRE just had a price increase. The cheapest thing they have is the 65cc D-port. They're now over $1900 before bolts and freight are added.http://www.krepower.com/Pontiac%20Aluminum%20D-port%20Cylinder%20Heads.htmThere are guys out here who don't have $10,000 + for an engine. If I had plenty of $ I'd just call Butler and have him build what I wanted and ship it to me. Then I'd pay somebody else to build my car and all I'd have to do is jump in and drive. But there are a lot of guys who have to do this as a hobby, and on a low budget, or not at all. A lot of what I've been getting back, online, is from engine builders who don't wanna fool with low budget hobby guys, 'cause there ain't enuff profit in it for 'em. Their attitude is, save up your money, and come back when you got enuff for a high end build that I can make some $ off of. Just one of the low budget Pontiac guys.
hi;ok regarding a 350 build, what i meant is that the one you speak of is one of the only ones i know about. nobody cares much about them.if a moderator sees this they can possibly post a link to that build for you or you can pm tuffnuff or pontiacman8.as far as budget builds there is no such thing. unless you answer all the questions no one can help you.summit sells eddy heads for 1200 each. kre are 1050.00 i was just on their site for another guy.you still need to buy rockers.if you run stock valves you can run stock cast trw or badger pistons.buy a 100.00 cam from summit port your heads and there you go.

Correct ? There are a lot of guys who just can't spend that much on heads. That's all I'm saying.
OK, maybe the 3rd time is the charm. Here's a couple of links to some 350P info. http://www.highperformancepontiac.com/tech/hppp_0806_little_big_chief_part_i_basic_machining/http://www.highperformancepontiac.com/tech/hppp_0807_little_big_chief_part_ii_assembling_the_long_block/
Apparently, on this site I can only put a max of 2 links per post ? I tried 5 and they wouldn't post. I tried 2 and they posted just fine. So I tried 3 on the next post and they wouldn't post. Then I went back to 2, and they posted just fine. So, unless I find out different, I'll assume that 2 links per post is the max allowed. If any of you guys know that this isn't so, please let me know how to include more links in a post. THANKS !

I haven't noticed a limit on links but wouldn't doubt there is one, to fight off spam robots. I see you already found the small bore article I linked on your other post. Hope you accomplish your objective, carry on.
i know a guy in st louis mo that built a 350 p for the engine masters thing when it first started. his name is Byron McFlesh (google serch).

ROWSLEY:i know a guy in st louis mo that built a 350 p for the engine masters thing when it first started. his name is Byron McFlesh (google serch).OK, THANKS ! The only person I could turn up, so for, with a last name of McFlesh is a female in PA. But then I'm a newbie at people searches. If there's one person with that last name, there are bound to be others. So apparently my search is not very effective. I thought I might be one of just a very few in the country with my name, but I found out that there are lots of us, and several even live in my state.
