Understand, I will do my best but I do not have all the engine stuff here with me in Iraq, So I am not going to know the cam specs.
Engine is a .030 over 427, It was a kit engine from PAW (Performance Automotive Warehouse) According to what I can remember, the pistons are 7.3 to 1. It has cast iron heads, but I do not know the CC or CFM of the runners. I do know that the headers that are on the engine now are restricting the engine, but they were the biggest that would fit without custom layout. They are 1 7/8 primaries to a 2 1/4 out the back, Super 44 flowmaster mufflers.
Trans is a well built 700R4, Transfer case is NP231, rear end is Currie 9"+ with 5.13 gears. Wheels are 39.5x18 Boggers on 15x14 steel wheels. I am sure that you need much more info than this but That is all I can remember off the top of my head. Oh it has a MSD 6AL box, MSD Distributer (Not sure which one) Mallory Coil (again not sure which one)
Carbs are 650 Demon Blower Carbs.
I only put it on the Dyno to get the F/A mixture right, so we only went to 5000 rpm, I don't remember what jet size we used, but I know that we changed them.
I had assumed that I was losing HP from all the driveline parts and the weight of the tires and wheels. Them shoes be very heavy.
Let me know if you need more than this to help and I will do my best to get it for you. Thanks again for putting up with such a novice to this stuff. I am enjoying the conversation and the knowledge
