[TJ's Chevy]

My plug actually burns a bit cleaner then that...and I'm running a 600 cfm 4 barrel and 65k coil(lol high energy alright) and headers.....barely...I mean Barely have the pedal cracked at 60 mph. The neat thing about the 4 barrel and headers an hei is it supplies enough fuel through the rpm to somewhat "change" the duration of the cam.....I had my 292 at 4000 RPM in 4th gear and it was still climbing. lol And that was with 95 pounds of compression..no not down hill. lol
