I would have a short deck one going together right now but I am forced to go with W7 heads and I have the Jessel rockers and intake. It's currently on hold till I find some at a decent price. I've been lead to believe that with the cam and pistons I have it would be in the 750 HP range. Time will tell

Nitrous oxide and ignition systems have came a long ways and are not nearly as hard on Motors when used correctly.. I'm betting 800hp.. is possible if done right... who ended up doing your machine work...

I have one and it's been making between 750 and 800 aspirated, it's a little thin at 4.100. Wow that's a lot of power was it a 48° block or 59

I go 162mph with a r1a 48° block at 3215 lbs. Use 200hp worth of nitrous to get there.

Mine is very basic no gas ported pistons or anything exotic.
