383

[SeventyOne]

Hey guys been on the board for awhile now but am ready to start tearing into my truck and want to get the planning done and squared away so here are some questions.

Plans are for a frame off resto/mod...

I will be putting in a 383 with around 400-450 lb/ft and want to know if a built th350 will hold up. I would be okay swapping in a th400 (that should hold up right?) but am not sure what that swap entails or

Will also be lifting the truck 4-6", doing the shackle flip, and want to run 37" tires without trimming. This will be a street queen/cruiser.

It's a 71 Blazer.

Can post pics of its current condition if someone lets me know how

Thanks!
