Use it with 3000 stall and you will smoke the tires at 40 mph.
hey bracketeer how much of a pop up is that piston?i have the option of 049 or 781 heads and if im right they spec out at around 120cc chambers.Another point you brought to my attention is the stall speed,if i decide later on down the road to put a overdrive tranny in the car,lets say a 4l80 which say puts me at a cruize rpm of 2500,will the tranny overheat do to slippage running with a 3000 stall?

Enquiring minds want to know

With a .030 bore. Jegs lists the Speedpro piston here. Part #844-L2372AF30. This gives you 9.6 comp at $39.99 per piston. The SRP piston will give you 10.0 comp but is more expensive. When you look at Jegs you will notice the next size piston for 10.3 compression is over $80.00. The same for the .100 piston that was recommended earlier. I run the 100.9 head so I get 11.3 compression with this piston. Since I have so much torque, no detonation on pump gas.

Higher stall creates more heat. A tranny cooler is certainly recommended. B&M make affordable, reliable products.
