I bought a 4500 Warrior intake from Warrior Racing back around 1991 and paid around $425 for it (iirc). The plan was to run a 2" spacer on it, but I never got around to putting it on a running engine to see how it performed.
Once my '67 bird is done, just a few weeks more now
, I'm going to see how it compares to the Street Dominator & RPM on my 455.
I've been waiting almost 30 years to run some fuel through that intake.
