hi i am new to this, i asked this question in the welcome posts. i think that was my problem. anyhow i will try again.
i have a holden 372 cui stroker, b cast heads,edelbrock torquer, cam specs are
228@50 with 525 thou lift. 10:1 comp, 750 vac holley. my engine made 326 rwhp through a 5 spd t5 at 5050 rpm and 464 ft/lb at 4053 rpm at the engine. almost everyone has told me my engine is at its streetable limit, with my current heads and manifold and cam, does anyone know if this is true? i have heard about torque power and strip master manifolds for pre efi heads. maybe yella terra dash 3 heads or vn heads. i need more power. what changes do i make now? thanks jeremy.
