11.5:1 4.06 x 4.00 340 block
Airwolf 220 heads off the 633 horse dyno thread
Cam motion roller 266/269 @.050 .585/.570 lift
Ported victor 2" HVH spacer
1000 hp pro systems 4150
1 5/8 headers with 3 1/2" collector ( too small but they fit the chassis)
Full 3" system
2950 race weight
Low gear 904 with 4.10 and 295/65 M/T drag radials
3600 stall T/A vert ....too tight but helps keep the short wheelbase Rocky launching straight.

Heads flow 273 at .400 301 @ .500 312 at .600, my shady dell stage 2's flowed about 25-30 less at all points.

Been Talking to Lenny at Ultimate about a looser but still tight-ish 4500 stall 8" but he wants me to see how fast this combo will go first.
