TF 210cc heads ported by Fox Lake, custom grind hyd or solid roller, either a 90mm TFS R or Box-R intake, or a Victor or Super Vic for EFI on an 11:1 408W shortblock.

hold the f*ck on when you're done ^^ that motor will be close to 600-700hp and wind out to 7000 all day long

and be happyhappy on 93 pump gas

FWIW a 450hp 351W will be offset by the weight gains and slower revving nature of the bigger motor, youd be better off doing a 347 off a 302...

My big thing is I want it to be a reliable engine. I'm going to try and take all the steps to do this right the first time
