Re: Opinions on BBF build- X275 Car

so why wouldnt a specific head program work for this class ....meaning a larger surface area port vs. more velocity , so you can fill it up the chambers with more nos , compare to your standard 1000hp bracket head ........ if you look at the dyno on my 562" /edel heads the torque is not a x275 buster ....... just a thought

its not the hp, its the torque.

I am not a head guru, but i thin nick is on the right track you really need to take in the consideration of flow vs velocity to get a good combo. these cars should run in the 470-490 range this year. do the math on the HP to run that fast, turbos 3300lbs, nos 2950, NA 2800lbs and all on a 275 radial. we have several of the cars that run in this class close to me. one has the sbf NOS fastest pass 4.97 another has the fastest MPH turbo car, also a SBF, there are so many options to go it is hard to nail down the perfect combination because therre is not enoph enoph on people running the BBF to have a killer set up. I will be watching for these combos this year while i finish my new motor.

Just getting started back up...been researching alot of combos and I think narrowed it down to A-460, big bore/short stroke. Will have definite plans and pics within the next several days.
