View Full Version : Pro 1's on 502

Here is a dyno vid of Jims 502. It started out as a 502HO from GMPP. We put a set of Pro 1's on it, with a custom HR from Erson. 255/258 at .050, with an Edelbrock Pro Flo2 fuel injection setup. The tq curve on this thing is unreal. I think, if memory serves me it spends most of its life from 3000-6000 at or above 500lbs. Of course it isn't your usual 10000HP internet engine,;) I think it is enough to scare the wee, wee out of any normal person. This is going in another street car, the kind that can drive across the country, turn around and come back.......

You think that is killer go check this 704 Awesome Engine on a Boss Hoss 1 of a kind in the world and we got it. 2 video's, talk about torque, It stayed over 800lbs from 2500 to 5500. Real custom piece that never does quick peeling the tread off the tire. We had a custom Dam Best 4150 made to go on the Dual Plane Air gap because of the height it needed to be. heres the videohttp://www.youtube.com/watch?v=rAQiyWc8OZY and here is the other 1 http://www.youtube.com/watch?v=JPI6fWR_nOI

That bike should be a beast to try to keep the rubber side down, but I hope he has a really good cover for that distributor if he plans on riding in the rain or ever having kids!;)
