Jon Kasse took one of my stock 63 intakes as a science project about 7 years ago. On the dyno with untouched intake the motor made 698 HP with 286 heads done by Kasse as well. Same day 45 minutes later with the ported manifold 780HP. Picked up 5 tenths right away! Largest gain we ever made with the motor!
Since that day the motor has gone through many many changes, and what ever we do still make 780? I can only think that the Intake is just maxed out? Maybe the heads? But I think its the Intake.
What carbs were on it, do you know what the heads flowed.
I had a flow sheet on the heads that I can't seem to find? From what I recall one set flowed 324? Maybe Dwayne Porters remembers he did a lot of work to them with Mike from HP motors. (If he pop's in?)
Carbs where 750's that Dale at CFM opened up to I think 950's
The motor was built for FAST racing so we where stuck using a lot of stock components
Doug I will try to get some pictures of inside the manifold?
