We arent talking about the intake, we are talking about the reason why you need the 383 intake. Arent they using a 400 block instead of a 440 block taking about 0.800 inches off the piston height? Isnt that the definition of cross breeding?
Pontiac made a 9.200 deck block that with a 400 we could do a very small crank and a very small piston skirt. We were told that is illegal. Several SBC guys I know say they are going to build a short deck 400 since their rods are like 5.35 inches. Wouldnt that be a killer combo too? Did NHRA allow that?
I dont blame the BBM guys for doing it, it is just that if one group gets it then everyone should. I could only do about 0.200, but a 428 could do about .400, and a 400 could do about 0.750.
