Ha Ha! Thanks for the comments guys.
The old 4/71 will not be big enough for the new engine so it has to go along with the old Rover V8 to fund the rest of my parts for the new BBC.. Thats the new "Belly Button Chevy"

I've been at the track all this weekend running the Slingshot and doing nitrous tuning on 2 cars + nitrous top ups for a few folk which inlcude 2 biker friends of mine who has 12 ounce bottles 12 Ounces ?? At least the other biker has 2lb bottles. I even cleared out the back seat of my truck and found enough parts to build an almost complete 150hp nitrous system for a nitrous newbie friend of mine. So I raced all weekend and came home $600 richer ! I still have a lot of nitrous stuff in the garage for the new engine though. I have two nitrous plates + a single 250hp set of noids + two additional sets of 150hp solenoids and a whole heap of plumbing to make them fit if I need any of this stuff for the new engine
