to stroke or not to stroke?
^^^^honestly if you respond to this thread again I seriously would love to see some kind of parts list or motor size or something showing that 850 pounds of torque and 425 horsepower build. It really stirs my thinking process, it's not something you hear often or in my case ever! and it's a drag race motor? I hope you don't take offense to me calling
" bull crap"!!
First off I don't care what you think. Second, neither you or I paid for the engine or the testing so why should I post any facts about something you may not understand. Evidently, you are having comprehension issues right now.
I will say this: we did make that torque. It was validated. It did make that HP and was validated. Some of the biggest pudwhacking heros came to the track saying the cars not hooked or the tune up is off and they left wrong. The didn't learn anything, they just left the track wrong.
With that said, it was NOT a MoPar this was done with. It was a GM brand. The original port work was done by a well known GM super hero (I hear he has his own cape too) and he wanted in on the "loop" while I corrected the heads for "big torque". When he read the final print out he said I was nuts...that I had killed every bit of torque and it would wind up like a sewing machine (among other things). For the record...I spent hours killing flow below .250 lift. Just murdered it. But by .500 lift they were killing the super hero ports. Then, to really piss him off, I killed the exhaust the same. The GM super hero now wants me to never pick up a grinder again. But my mid and high lift numbers were ball busters (because the customer wanted TORQUE and NOT horsepower and the customer is ALWAYS RIGHT).
We then added compression until we had 11.85:1 and this was a pump gas engine. Now GM super hero guy wants to strangle me. He tells me 550 HP and 520 TQ. So then I tell him I put as much cross section in the intake as I could without welding. Now the GM super hero wants to call a 5150 on me and have me fed jello 3 times a day.
In the end, the customer got EXACTLY what he paid for. And it ran exactly what I told him it would.
You can't fool mother nature.
FWIW this was a corporate GM build well over 500 CID. We didn't do anything without long, comprehensive phone calls with my cam guys. I spent more than billable hours on those heads just in testing. If we had used an HP cam, took 100 inches out of it, it would have made 650-675 HP and about 600TQ and it would have ran in the 9's. Instead, he had an 11 second car to match his 11 second mouth.
Anything else?
