Ed, I knew there were not the greatest photo's, but that's all I have on them.
I was also told they are 15 deg. heads??? that I can't comment on. I have know the last3 owners of these, but this was after the fact. Here is what I know, or should I say "told" of these from the people that owned them:
Ran, or tried to run NHRA Pro Stock back in the late 90's, 97 or so. They guy was buddies with Ray Franks and would travel and stay at his house. As you can see, they weren't "REALLY" what was needed at that time for Pro Stock, so the owner at the time, switched over to a 500 inch nitrous Pro Mod for a bit. That's where the epoxy came in and I would gather the larger ex. port possible. After a few years with the nitrous, the guy switched to Blown Alky and sold this stuff off. Mine was is back-up set that was told to be a identical deal to a Wj deal that the guy bought???
The next owner had the single 4 done that you see on a 460 inch motor and ran into the 7.70 with this set-up on a small jet???? I have spoken with him at lengths and he said he really like this set-uo, but got caught up in the 10, 11, 12 deg. stuff and got a set of 12 deg. heads, but only picked up a bit, like a tenth and a half.
He sold them to the guy I got them off, who was using them to run NPS in the NSCA (old NMCA) deal on a 572. Now the motor was no where near as strong as my short, and the new drive who was just learning made less then 10 runs with them, and broke the block. Car DID run 8.01 with a 28 jet I recall @ 3350 lbs when they broke the block right down the center. Now I know this guy had a bit more done to the intake as I have the flow #'s right here after the intake was done.
I does say there EPD's on the sheet from 2004. 2.400/1.900 with the cast single and 4.500 bore, they flowed between 469 on the best and 451 on the worst. Now I have a 4.6+ bore, so I could get a bit more. But the original owner told me that the velocity of these were amazing. I guess they accelerate really well to from what I gather.
So, there you have it, my novel for today, LOL
