305 to 350 issues
Hi guys hope you help me... i have a 92 305 tbi and i want to swap it to 350..
as you know, the 1st gen of 350 divides in two types, the first one till 86 with 2 piece main seal and the second one with 1 piece main seal since 87..
I want to buy an aftermarket top end kit but the best ones and more complete ones are made for the 67-86 350´s and i want to use a block from 87 and up..
my question is.... can i buy this new block and put heads, intake manifold, camshaft, pushrods, valve covers, rockers, i mean:
87-00 block with 67-86 (everything else not counting obviulsy the crankshaft)??????
and then, to use a 4160 holley carb with my 700r4 trans, i just need two different brackets for the acelerator an TV cables??
thanks for your help. im exited about start swaping but i dont want to buy things i wont be able to use!

all your accespories should swap over if your heads have the same bolt holes which most if not all do.
