225 Modified Slant

Yes it seems your 66 valiant would be sinister at that, a real sleeper. Since nothing is really known about the internals, maybe for decent street ability I'd stick with a Holly 390 CFM 2 bbl. 650???
What is a sleeper is my 70 Dodge Challenger w/ the 225 /6, 904 on the floor. Go-Mango Orange, Black interior. Nothing over the top, mopar elect. Ign. , Super 6 set-up, Hooker headers 3 into 1,real dual exhaust 2.25" w/ H pipe, glasspacks. Open element air cleaner K&N, Accel coil. The addition of the dual scooped hood and T/A ducktail rear spoiler is a nod to it's performance heritage at a glance.
