273 blower cam

What are the current valve sizes? 1.88 intake? IMO with a blower, you'll likely never see the difference with 2.02s.

1.78 and 1.5, stock sizes. I ran it on desktop dyno on my old pc and it showed a substantial gain with the bigger valves. 20 year old computer program but it's all just fun in my head right now anyway.

The speedmasters are jeweled chunks of aluminum that are fun to stare at and a weight savings. And right now paper weights sitting on a shelf

I bet it is, aint nothing like roots blower torque! A 318 would probably require 1:1 or overdrive blower ratio with a 4-71 to generate the same 5PSI of boost as the 273.

With the same pulleys I could run it at 10% over, and like you said probably be around 5. And then the back tires wouldn't stand a chance. I live across the street from the police academy and they can find me lol
