Factoring in the minimum 400 pound difference between the 2 trucks (Reg. Cab vs. a Quad Cab), your numbers are correct based on both trap speeds and on r.w.h.p. comparisons, and equate to a 50 horsepower difference. As in Post # 111 above- there is an approx. 50 horsepower difference between properly ported Gen IIIs and a cam and a stock set of Strikers and a cam.
FIFTY horsepower is quite significant.
After a Gen III N.A. build is complete (with well ported Gen III heads), where would you find an additional 50 horsepower and at what cost (either monetary and/or drivability sacrifices)?
I asked myself that, and for me it was an easy decision.

Cost was the prohibitive factor for me. My complete build was under $6k. I'd have probably spent twice that if I went with the strikers since I was paying a tuner to do the work.
$6k for 50 hp wasn't worth it to me. If I did my own work like you I may have went the other way.
