choosing heads for 408 stroker

Rhauf · 01-20-2009, 07:49 PM

Okay so as some of you may know i posted a thread about my 408 having no balls. i have done some research and decided that the heads i have are just too small ( edelbrock RPM heads, 170cc runners, 202/160 valves)

the engine is this:

408w stroker 10:1 forged pistons (with 60cc chambers, that is)
crane powermax cam 224/232 @050, 540/560lift, 114lsa.

this is probably all that is relevant. are my heads too small? what should i go with, i was thinking the edelbrock victor heads. would this be worth spending the money? or are the heads i have fine.. what about AFR? im looking for good power in the 2500 to 5800rpm range. currently its only making about 250rwhp on the dyno.

thanks for reading.

Its in a full size bronco, with a c6 trans (2500 stall), would you still go with 108 lsa?

Well seeing that the truck is running now (and well broken-in) it's really kind of a moot point (especially since taxes just destroyed my savings) its not for towing or racing, or rocks, it's really just a build to go have some fun with in the sand, mud, dirt, hill climbs, desert, etc.

i really just decided the heads were too small because now that it's finished it really doesn't perform up to my expectations, and i guess i blame the heads. i probably should have gone with a big block.

here's a video and a picture just for fun.
