Duration - Valve Lift - Lobe Lift - LSA - Int./Exh. Werby: thanks to 5spd GT, I do believe you will find all you need here, and more! 050 was 210-204 duration, 115.5 LSA, and 2.5 degrees retard (118 intake CL and 113 exhaust CL).Īnybody know if this is right for the 1987-1994 5.0? 050" events of the stock 5.0 cam, does anyone know for sure? Hard to figure.īTW I am sort of guessing the. I'd blame the dyno but the first run with the iron heads is a pretty close match. There must have been some real magic in that parts combo. On rare occasions I've had the Gonk differ from the dyno by over 12% but not with this common a parts combo. Now the 165 AFR heads, TriY, Weiand, 625 Road Demon:ĭown 24hp from their dyno number in the mag.ĭown 20 ftlb and 41hp from the dyno number in the mag. Here is what I computed in the "G" without any fudging, just keying in the parts combos I already had:Į7TE heads, stock headers, Weiand, 600? Holley:įairly close so far vs. index.htmlI cannot get the Gonkulator to equal that 405hp either. You also have to take into consideration that your break booster is set off the vaccume as well so if you go with to big of a duration then you'll have to do something about the vaccume to your breaks. I was always told the same thing about the speed density thing with the cam and yes, it probably should be done with either specing the eec with the rest of the truck or putting mass air flow on but if you can handle the wierd idle and the wierd feel under 1500 RPM (due to vaccume) then you can do it. Everyone told me that it's set to be a 1500 - 6000 RPM cam but it's an idle - 5500 RPM cam that's been matched to my edlebrock intake and my bigger throttle body.
The only problem with this cam is that it doesn't make enough vaccume for my eec so it has an erratic idle and it's a little jumpy untill about 1500 or so RPM's. That's a bit to tall of a lift for me, it's not a race truck I just wanted the little bit more low end. I have "stock" pistons and was told that I should be able to run up to a. I did have new springs put on and my heads along with my getting my heads and deck "true cut" so no worries about head gasket sealing right. 501 exh (I belive that to be right) and I have the speed density as well. I'm about to put 1.7 roller rockers on that changes that slightly, something like a.
duration (advertised is 260 intake and 270 exh) and my lift is. I have an aftermarket cam and here are the specs 204.
