I have a 91' GTA w/LB9 and a 700R4. I just bought a early model 350 block, crank, rods, and pistons. I want to have it redone and stroked out to a 383. Will my TPI heads fit? I know ill have to have a chip burnded and etc. But my only concern is fitting. Thanks

 

Yes, heads will bolt on. But probably not the best choice for a 383.

 

Why not a 383? What should i go with? And the block, im gonna say is in the late 70's.

 

Well, I'm assuming you'll want to use the 305's heads? you currently have. The small chambers and valves would require some extra work ($-wise) to flow well for a stroker.

Best bet to get an idea would be to search for 383 and Heads, see what oithers use and how they perform.

You should also post your engine goals too..i/e 500hp/500ft/lbs require much more head than a 350hp/400ft/lb engine would.

 

So LB9 heads and L89 heads arent the same exact heads? Is there a specific way to see other peoples setups? With out haveing to look at everyones profiles?
