Well there is no porting allowed, stock valve train.
I am hoping to get about 6500rpm peak. I run on a 1/2 mile D shaped asphalt oval. Semi flat. The front stretch is part of a drag strip.
I need to find a good combo with 8.5 compression MAX!
I have been having a over heating problem with the 351W. I am using factory pulleys(rule) on the water pump. I just found a smaller Stock Crank pulley. Hope I can get every thing to line up. I use a 3/4in. wide belt, Non-serpentine type pulley system, Standard Rotation water pump.
I picked up a bracket from a 90's crown vic. to place the power steering & alt. both on same side(left), To use only one belt.
Also a lean condition didn't help. I use the stock electric fan from my 1990 T-bird & a Griffin 2 core racing radiator(big Grey area). The stock 1 core was no match, Boom
-- blew the side out!
