My new block is 4.50 bore and 3.750 stroke Ken's new heads and an 8:71 on top. Should rev up just fine....
Can imagine how much air you can shove through through those heads with an 8-71 cranked up. I must ask why that direction of max bore and tiny destroke to get 477
We are limited to a specific fuel pump flow rate in the class I'll be running. I wanted to run the new heads soooooo that's what you get. Also the new heads like the rpm
Ben the Crower crank was ordered destrocked. See attached spec sheet. We were originally going to be at 445cube due to the fuel pump limit of 20 gallon a minute. 450 cube is about the limit of the pump. The new heads need about 4.500 to max out the bore so that is where it is. A few shots
