If you are unsure about all the machine work and everything done it does not hurt to take it to someone knowledgeable to look at it for a look second opinion. Can save you alot of heartache in the long run.
Definitely get a second opinion. Sorry to hear of your loss, you aren't alone, several of on here have suffered the same sort of grief in the past few years. The strange thing about project cars is they can be both therapeutic and stressful when you are recovering from the loss of someone you love. For me, I spent months after my wife died replacing floor and interior in my Firebird (which she bought for me) and spent a huge whack of cash on a new killer 400. I hardly drove it at all this year and the new engine is still waiting to be run on the test stand. Take your time and let the project flow naturally, work on it when you want to and walk away when you must.Steve
A little help... 'cause we don't all have to learn the hard way!
i was on the phone with the machine shop and he said the guy he out sources the crank cutting to says the crank they gave me is correct 20 on the main 30 on the rod.i had two cranks here before i sent it out one was for the 455 the other was..here is the no. off the crank 496452 if some one can tell me what block this came from with 100% certainty i will know if i made the mistake i researched the no.and it matches the crank they gave back to me.any help would be greatly appreciated
Crank casting number 496452 is a 75-79 350 crankshaft
thank you very much.i had bought a 400 long block some yrs ago,at least thats what i was told and im almost certain i researched the no.to be sure it was in fact a 400 and built in 76-77it ran strong till my son spun a bearing i pulled it apart and used the heads ( 6x4 ) for the 455 i did some research on the heads today and looks like i coulda made a huge mistake on this crank issue the heads i believe were used only on the 350 in 76-77 but im not sure i looked for the distributer but didnt find it yet
I had the same thing happen to me. I couldn't get my new cam to turn freely in the block so I took the block and the cam to a different machine shop and he said the oil passages were almost plugged. I told him to completely check the block while I came home and got the heads for him to look at (I bought a set of 6X-4 heads and told the first machine shop to magnaflux them first thing so I could take them back if they weren't any good and he said they checked fine). When I got them to the second shop he said one had a large crack between the intake and exhaust port - the first shop even did a valve job on these heads. I tell you, incompenant people SUCK! Even though it cost me an additional $1000 it was worth it - I just hope the first shop goes out of business! Good luck!
Savage73: My heart sympathy to you and your family. I know what its like to loose a loved one that is so close. Bob
Savage73:I know it maybe a little late. But the next time mark every piece you bring to a machine shop. I recommend that to anyone that leaves their parts for just cleaning. A $10 Etcher a steel stamp set, will do just fine. Mark all your parts with the same number. If you can hide the number or name, whatever. It happened to me once also. It was 30 years ago. When my crank was about to go through the guys window he made good for it.Bob
the 326,350,389,and 400 will have 3.00" mains. a 421,428,and 455 will have 3.25" mains minus what ever they have been turned down.

good news for me the machine shop called and said there was a mix up with the cranks.its good to hear cause i was starting to second guess my self i'll pick it up and take it and the rest of the stuff down to the speed shop to have everything checked.the local speed shop has been around over 40 yrs. and has a very good reputation.the old man that started the shop also teaches at local community college
One time I took a set of LT1 chev heads to a machine shop two days later they called and said they needed another set because they were cracked .I gave them another set of chev 350 heads and never seen the LT1 heads again ! The engine never had any water in it ! Make sure you mark your parts and get the same parts back !
thanks very much for the advice and kind words every one
