ok, couldn't remember. That is the only other intake I see available with the Dominator flange for B block. The TF would be my #1 pick, but it wont fit under my hood with adaptor and Andy said it lost 18hp with the 4150/4500 adaptor on it. guess i could put my 950 on it, but seems like that would be going backwards.
A Wilson ported M1 with standard ports worked better with my 270 heads than an OOTB Indy 400-2 intake. Once the 400-2 was ported then it worked better. The Indy 400-2 out of the box was a pig. Once it was reworked by Wilson it ran pretty well. Your results may vary. I was working with a fairly well sorted out combo. That was a pump gas 470 that was making over 750 hp. I think the best set of pulls was 780 hp. Most guys don't spend the time and money to dial in a combination like that. If you knock 100 hp off the engine then the OOTB intake probably works just fine.
