Not bad and an improvement over E7's and the iron gt40's but... IMO, they are not worth the cost new. You could buy some nice used TF or AFR's in the same price range.i was thinking ford racing turbo swirl GT40 heads? yay or nay?
I wonder as well but a lot of people do it. Cheap and plentiful?It really doesn't matter if you're thinking of using e cam. You wont be happy either way. That cam is not good in a light Mustang, so how could it be good on a heavier truck.
yeah, they will bump compression if you have them milled.a set of gt40's is what you want. Will bump up compression and make more torque.. ideal for pulling
