Guess my dyno numbers!!
Nope! Your heads are ported, and hp comes from the heads, so..
Should hopefully be getting to the track soon. My best time before the rebuild and headers was 13.07 @ 107 in really great weather. Most of the time it was around 13.2 @ 105. Hoping for mid 12's once I get used to launching it again.
Well a Mustang dyno reads 7-10% lower than a DynoJet so it probably would have put down at least 350rwhp on a DynoJet.
The only way to tell if its running how it should is to get some track #'s. I laugh everytime I see someone post up track results with a trap speed around 116mph or less when they dyno'd 400+rwhp.
