4250 stroke / 7.1 rods
Old 90’s 505 crate motor MP performance block
Bores bushed and sleeves installed from MP from new - didnt know til we started
the build, lol. So it allowed for 70 over easily .
I think its 515 ish .
Dished diamond pistons / 9.5 ish compression.
The TF 240’s were an afterthought after reviewing costs.
In pretty sure they cc’d less than my actual 84 cc’d on my 452 castings -
The book shows 78cc on the 240’s.

getting the Cast heads re-ported and flowed to breathe better than before
would have cost more thsn new AL heads that came CNC ported but
I dont believe polished
since i can just barely see my reflection in them, lol.

This was supposed to be a 9:1 motor cast heads to run on watered down gas.
I kind of only originally wanted 550 reliable horse with consistent torque. lol.
I would say I should be able to intimidate hellcats - my post car is only
3800 lbs or less .. So I guess Ill take it .
