Hi I just bought a 1970 lemans with a 350 in it. I have an uncle that would sell me a Buick 455 for cheap. I'm trying to. Decide whether to buy the 455 from him and put it in which seems like its harder to find parts for or rebuild the 350 and soup it up a little bit. Any opinions would be appreciated. Thinkers
If its complete and runs good, snag it and run ot while you plan a Pontiac engine build and save for it. You'll need to take it easy on the old transmission. Sell the 455 back to him when you're done using it.
you would have to soup a 350 up a lot to match a stock 455 in a heavy car. 455's are easy to get parts for try sdu,,it and butler perf etc.
