I launch just off idle at about 1900 RPM and seem to be going through the traps at 6,700. I shift at 6,400 but it seems to be falling off in power by then.
The car weighs 2,800 or 3,000 with driver and gas. This calculates to about 650 HP.
No nitrous or turbo or electronics.
I'm pretty happy with this, but you always start thinking about what could be done next. Selling the torqueflite and get a powerglide, would be the next logical step I suppose. Any suggestions? Oh, and the timeslip was my best the yesterday, but I redlighted cause I couldn't see the last amber in the setting sun and tried to leave on the second last light and guessed wrong. The other driver saw my redlight in his mirror and let off. The competition is stiff and if you don't get a good light, you can forget it.
The engine was built almost entirely based upon Andy's book How to Build Max Performance Mopar Big Blocks. This book should be required reading for any big block driver. The car and engine and transmission was homebuilt in a two stall garage with only ordinary machine work and the roll cage done by outside help.
Certainly not the only way to get into the 9s but this seems to work.
