Desk Top Dyno
I had the older version of DD5. But it doesn't work for me now. I can get pretty close on those numbers. But the engine is not assembled at the time. I still need to purchase a few parts. I'm trying to make 740 hp with a W5 head, 3.79 stroke 4.185 bore 422", solid roller and about 14 to one
Hey buddy.
We have talked about this before . It would take exceptional everything to get anywhere close to that kinda figure, that could be backed up at the track. Not saying it’s impossible, but it would be ultra top shelf power for a W5 deal.
I know you have mentioned a guy you know making supposedly that kind of power, so maybe it’s possible.
My old motor/ car( after I sold it) had several upgrades made( things I wasn’t willing to do when I had it) and has been very recently 140 mph at 3220 pounds on leaf springs. Spring eater roller cam.
When that motor was dynoed at Best Machine it made 708. They were a super reputable shop( recently closed as the owners retired) Most anybody in the Mopar community knows that shop and the work they produce, they did all the machine work for both of us.
That is the high water mark I have ever heard of , at the track, with those heads. This is currently a 14+ compression deal on gas, no vacuum pump, shelf headers( TTI W 5) .
So alky, vacuum pump, maybe extra power could be found.
This all said..the casting quality of any of those heads flat sucks, even the supposedly better blue plug heads. They leak bad too. Been there done that with those. Thin spring pockets when ported, just frankly knowing what I know now, would never invest the pile of money in them needed and expect long term reliability.
Victor heads would be more reliable and make more power, or even Indy heads
