Cheater plate!

Many years ago (2001 ish) I built a 360 for nitrous (JE forged pistons, file fit the rings for nitrous) and used a cheater plate. I used stock rods, but I had ARP bolts on the rods (and ARP main and head studs). My ignition was all MSD (6AL, blaster 2 coil, billet distributer), ran 28° timing. Fuel side was a Holley blue pump. I think that was all....anyway, in Colorado at Bandimere speedway (about 9000' DA in the summer) the car went from high 13's NA to 11 flat on the bottle....twas fun. :)
Forgot to add...plugs were NGK R5671-9's (pretty cold). Unfortunately they would foul out under normal street use pretty fast, but worked well with the spray. I also ran a mix of race fuel and 92 octane gas (about 50:50).

Also to note, if I recall correctly the 11 flat runs were on the "180" shot pills....it ran 11.4 on the "150" shot.
