Supreme Air, just wondering why you run a carb vs fuel injection? Because thats the way the builder went, or is there some advantage?
Somebody told me that at high rpms f/i cant deliver enough fuel ?F/i will help with fuel economy though.
it all depends on the fuel pump, plumbing and injector size.
btw the plumbing is also a sure way to spot over-inflated hp claims

; if a guy claims to have 1000hp and has only -6 fuel lines and a smallish pump on the EFI engine you know he is BS`ing
IMHO a carb is less expensive to build... the price for just the fittings to properly plumb a big HP, big CID engine can give you a heart-attack
IIRC on FlyingRyans TTBB i used -12 main fuel lines feeding into a "pool pump" sized high pressure EFI pump with the -12 output splitting into 2 -10 for each cylinder bank fuel rail. return lines are also -10 ... a little on the overkill side for his current tune (pump gas) but the engine is ready to easy produce about x1.3 the current hp if he would switch to "E85" and at least x1.5 on race gas.
as mpfi632 already hinted; i think next time we would do a "two injector per cylinder" setup; a single large injector is kinda tricky to tune for start-up and low RPM
