Forged 325,347,377,383 ET/HP Thread Hey fellas this thread is devoted to annotating how much RWHP or FWHP your cast iron/aluminum 4.8,5.3,5.7,and 6.2L make and your ET/MPHs.
I would to see what your combo is engine/heads/intake/trans/rear W/gears/ Power Adder(s)(Turbo/s, or Centri Blower) are.
You guys may make me reconsider my desire for a F-1A blown 390.
Thanks ahead of time for all of your posts.

iron block 5.3 bottom end, ported 243's ls6 intake, ls6 cam pt7675 made 580rwhp on 12psi ran it up to 18-20psi and ran 109mph in the 1/8th no dyno yet with it turned up. mid range torque at 4000 rpm is ridiculous.
