If you can't make over 850 N/A you are doing it wrong

With AFR 220's and a Super Vic? Not happening.
Sure it can. 15 years ago I made 620 HP N/A with a 347 Victor Jr heads and a Victor Jr Intake with a smaller nitrous cam with less compression. With an extra 100 cid and extra compression, better heads, intake and cam it is a walk in the park.

With 13:1 454 Windsor, afr 225, super victor we made 707 at high 6k low 7k, which is right where the math said it would make. Also set up for spray.

I would guess yours will make a few more. How about 720?

Just received my custom pistons from Ross and calculated my compression ratio, it should be somewhere around 14.64:1, plan on running a fogger with 250 shot with nitrous 120 fuel, my goal is 5.50's or better in the 1/8 mile, any opinions?
