I am running a set on my engine builders Duster, and so far the pump gas motor has pushed it to 10.40's and almost into the 10.30's, just curious how fast you can go. These are unported and so far, not being a wedge guy, I am impressed on how hard the car leaves. It carried the front wheels this week +30' at about 10" off the ground.....

We ran 6.61 last week at over 102mph. I have to look and see, but I am pretty sure we had one time slip at 103mph, but our gearing is for 1/4 racing. I am impressed so far, and I am sure 6.50's are just a couple hundred rpm higher on the launch, but I leave nice and easy on it while we dial in the 4-link. I had to actually abort one run as we got the shock damping too tight, but we made some nice progress on the next couple of passes. So far the best 60ft has been a 1.465s...

WHAT INTAKE IS THE BEST FOR THE EZ-1 HEADS A MAX WEDGE OR US A SINGLE FOUR? Are you talking about a factory max wedge intake or one of the indy intakes? The factory maxi intakes are 70+ HP down on a good single plane. Getting old just means you were smarter than some and luckier than others.

That manifold is a restriction, if nothing has been done to it. The newer single plane intakes will outflow them. I know they are great for the cool factor, but for performance they are down. Read AndyF's book, he did back to back dyno tests, down 80HP.

Sell the cross ram to someone that needs it for a nostalgia super stock if its modified or to someone doing a restoration if is unmodified. The cross ram intake will bring enough to buy a good single plane and a new carburetor. Getting old just means you were smarter than some and luckier than others.

Revved it to 7000 trying to get in the 10's, spun a bearing and a rod exited the sump. New 440, smaller flat tappet cam, better recriprocating assembly, more comp, old heads int and carb, time in sig and i think there's maybe a 10.1 in the car, shift at 6200 trap at 6500.
