225 Max Performance Recipe?

I guess this type argument can be found on FBBO involving the poly 318, aka wide block, yes it costs considerable more to build, than an A engine
I disagree!
I took out the B/RB but they could be included.
HOWEVER!!!!!!
Cast replacement pistons are inexpensive. Forged slugs would be pricey.
There are off the shelf cams readily available from Crane Cams & Racer Brown to name a pair of places.

The intake manifolds are being held hostage by hoarders! That’s a major problem.
Headers by tti are the only game in town. At least there good headers.
Those are the expensive things and the tti’s are worth it. Not so much the intakes. CCP has a new intake for the Poly. $$$
