I am wanting to run a 800 cfm on my 462 Pontiac. I am running a set of ported and polished 7F6 H.O. cylinder heads. I will be running a H.O. dual-plane intake.

2" Hooker headers

3" exhaust with 2-chamber Flowmasters

Roller cam with 605 lift

What would be a good starting area for metering rods. I want serious performance from this application.

I am wanting to improve my quarter-mile performance.

4500 stall converter

3.73 gear

275/60/15 drag radial 28" tall tire

Car is 4250lb race weight. This is why I call the Pontiac "Big Red."

The engine has a Doug Herbert Roller Lifter Camshaft

I will have to find out more details on the cylinder heads. I do know they have had some extensive work done on them. Gary Pollock is the gentlemen that did the work on them. Gary had done head work for Jim Moran in Illinois for years. He actually did all their head work. Even with all the work, they probably do not flow as good as a set of stock Edelbrock aluminum heads.
