350 engine question
My 71 has a 327 in it and it's old, lot of miles. I want to put a 350 in it, here's what I found 1989 Chevy c20 with 43k on engine and tranny th400 , I should be able to just swap that out right? I'm new to chevys so I always ask..

Re: 350 engine question
The engine will swap right over. If the 89 has a computer controlled carb, you'll need to use your old carburetor. At least I think the K20 was still running a carb in 89.

Re: 350 engine question
A few things that come to mind quickly are things like dipstick (right or left), fuel pump (is the block milled for it?), and if it was me (assuming you wouldn't go with some performance parts in the process) I'd strip the new engine down to bare heads and block and use all your old sheet metal, accessories, and manifolds so everything is sure to bolt up.
IIRC the heads from the throttle body trucks aren't anything special - not the worst but that may be a consideration in whether this engine is worth the trouble to swap in.

Re: 350 engine question
I think I might be able to get the whole truck for under $500 and resell the bodg for $200 for scarp

the valve covers will be center bolt so the 327 ones will not bolt on. without adapters fuel pump boss is drilled .. his 327 intake will not bolt to the 87 up heads.. the bolt angle changed some have ovaled the holes in the intake , I've never done it.. so no idea how tricky it is to do that and it not leak. the flexplate flywheel will need to change as an 89 will be one piece rear main seal.. If he can get the truck for 5 c-notes and it's got 43k on it.. and it's not 143k.. I'd stuff it in and call it good.. change parts after you know it's a solid piece..
