frankly, i have yet to have heard of a trick flow small block motor that has had performance that “ wow’s me”
That said, there may, and likely are, many builds i am unaware of.
To me, they appear to work about as well as a moderately rubbed on eddie head, not bad, to be sure, but i think they will end up in 3rd place among offerings i know of. The new Bloomer head, the hard to find Airwolf head, then the Trickflow.
