| Re: TPI on an old block? the bolt angle your talking about has to do with the heads you use.that can be fixed,other than that they are the same 305-350.there are two different styles for each motor they went piece rear main and different dipstick after 87.the heads all interchange.87 up has a different intake bolt angle in the center.there are workarounds for that. but tpi will work on it no problem.
a 383 is gonna run you some cash and depending on how its built the tpi will become a restriction and you'll have to upgrade the tpi intake,throttlebody,runners,and run you some serious money
