Appears to me, looking at the 60' times, that your suspension/chassis is working GREAT. I agree with you, that it should MPH alittle faster. I would suspect a lean condition at top-end of run. I would kill for your 60' times!! I'll trade you my MPH(104-105) for your 60'. If you like drag racing, support your local track.

I also had a problem with my motor laying over and it was the carb too close to the scoop. I ran without the hood and it was back where it normally is.

Its at 88 jet front with PV and 94 rear. the hard starting is the telltale symptom here I believe. But that could something to look at. It is kinda slow all the way down the track. I have run this same specs of a motor before on race gas and more compression and it was ungodly powerful and fast in my Sapporo. that gear drive has my mind boggled some. I guess I could put a new chain on it and test it out with straight up or retarded settings

At 520 horse a blue should even likely be adequate. Could be filter, pickup, voltage, regulator......

It kicks back while cranking. Doesn't pull down on the gear change. Smells of high cylinder pressure and big torque. How much cylinder pressure does it have? Leads me question if the cam isn't advanced further than desired? Doug

Filter is on of those inline tubes with a mesh in. Shouldnt restrict much? From filter i have a an8 hose to the regulator witch is the cheap holley modell. After reg i have jegs prebent steel tubing kit. Cant really see the restriction exept maybe regulator.

I use the Holley black pump also and have the regulator press set at 6 psi. I use 3/8 line and a stock fuel tank with a stock 3/8 sending unit. It feeds my car fine as I have no fuel starve problems at all. I actually had the red pump on before and switched to the black just to be sure it was getting enough fuel but it ran the same 10.70's with the Holley red pump also. Ron
