Okay...................some of you have been asking for the Dyno Reports so here they are:
Not too proud of this one on the Dick Harrell Supercar. Dyno Report on Phase IIIX DH #30. Only did 514.74 h.p. at the crank (447.6 X 1.15). You have to take the rear wheel horsepower and add 15% to it for the loss through the drive train. Mike Carahan discovered that it was only firing on seven (7) cylinders instead of eight (8). I originally brought Mike Carahan up to my house because this car was running way, way too rich so he thinks I probably have a fouled spark plug so that will be our first step...............replace all eight (8) spark plugs.
Dyno Report on Phase II ZL-1 #17. Did 503.24 h.p. at the crank (437.6 X 1.15).
Not too bad for a 475 h.p. engine package.
You have to take the rear wheel horsepower and add 15% to it for the loss through the drive train. 
Dyno Report on Tom Henry Racing SS #21. Did 436.08 h.p. at the crank (379.2 X 1.15).
Not too bad for a 380 h.p. engine package with the addition of Dynatech headers.
You have to take the rear wheel horsepower and add 15% to it for the loss through the drive train. 
Dyno Report on Dale Earnhardt Intimidator SS #68. Did 409.285 h.p. at the crank (355.9 X 1.15).
Not too bad for a 381 h.p. engine package.

Thanks for sharing - pretty strong numbers - now go drive them all so they don't go downhill.
My 2 cents :twocents-twocents: .............. If cars sit & are not driven & only started up once in awhile they WILL LOAD UP. I know!
Gotta drive them - get them warm & be sure the fluid gets warm & brakes are used.
Oh wait a minute............ I drove HRE 2000 & hurt the motor. What do I know?
