Great looking dyno cell MER! I hear only great things about the work you do. Good to know you are another knowledgable Holley dealer. I'm not in the EFI crowd, but know some guys that could definitely use your services, and will be sure to send them your way.

Desert rage, what was the conclusion of testing on the water?

Also what cubic inch , heads and cam duration at .050 are you running on both of those motors you built?

AFR is suggesting their 300 Oval port and I'm not sure of that ! I like the 325 or 335 they offer Looking to build either a 548 or use a4.375 BRC crank I have and build a 557.

Thanks for any input

Are you changing to Holley electronics only or are you changing the intakes also?
