Some questions for anyone who is running this combo. Will a Comp XE274 clear the pistons, how much race fuel to add and not ping
(if needed). My only choices are Flat or domed. The motor was done with recessed TRW's .030 in a van. Now its apart and headed for a Ranchero as a fun car. I don't care about adding race gas if needed. Just want a fun ride. At current bore measurement KB pistons need less clearance so can't use. I have about .0035-.004 so its those 2 pistons I spend all my time debating on. Thanks for any input from anyone who is running those.

 

With no responses I might be the only one to try it. ????

 

What heads are you running?

 

The D3 which should be 92 cc. Block has .030 deck.

 

FYI, You can run that cam in there with no worries of valve slap. I am running flat top pistons with a much larger Comp Cam. I milled the heads .020 and the block was decked .032 to true the whole assembly.
