I'd rather exchange compression for head flow.

Hard to beat head flow.

Good running 454 for 8.2 scr. I have read that article before. Did good for what it was.

Just got the cam last week for that engine mentioned earlier Ponjon.. So I don’t know hp or e.t. yet. Shooting for around 530 hp with the ported stock intake, qjet and ra manifolds. 6x heads are 190cc. I don’t have final flow numbers yet though. Hoping it kind of keeps up with our 510 cid pump gas 69 Charger with 10.50 scr, ported cast iron heads and a big flat tappet mech cam. The Trans Am needs to come close to 11.50 to match my brothers et in the Charger. I think it has a shot. My brother and I have had the charger since 1988.

The dished icon with the 2802 or 60243 Crower looks like a good combo to me transam474. IMHO, no reason to do the flat tops unless the heads cc’s are larger than expected.
