Heres the little brother to Wayne's throttle body, flows 1200 to 1300 cfm, I did near 550 ftlbs @ flywheel with 42's in a mitchell 427sb. Extremely mild cam, I believe theres easily 600 in it using the 42s. The throttle response is very quick.
I wonder why Wilson milled the injector bung bosses almost completely off before installing and welding the bungs, hmm?
Rich
I have both 50#'s and a set of 42#'s so if I need to I can change them out. The throttle body is a 2" bore, plus I have a Fast 4150 throttle body like the one Rich used if I need to. As far as the intake, I wanted to keep the one the engine came with.
supreemefi No offence taken I'm as rookie as it gets. I have both set ups this is the one I wanted to run, if it doesn't work I'll go with the other set up.
You run that thing pig fat and you'll knock the oil rings right out of it -- and it will forever use oil...
Go smaller... and if it's a little lean on the top - then boost the fuel pressure a couple pounds. Remember that injectors are "rated" at 43 #'s of pressure -- they'll flow plenty more at 45 or 50 even.... and the thing will idle FAR better with the 42's than it will with the 50's... TRUST US.
X2 except you can run anything pig fat with a small throttle body and little injectors as well, just harder to do.
I guess he has money to burn, wish I did!
And I hate to be the bearer of bad news but unless you saw the dyno sheet/session yourself, you better bank on the true hp being much closer to 550, all the more reason to use the 42's.
We had one of these on a Superflow 901 dyno in Jacksonville Fl. Best we saw was 498 after a day of tuning. But once you get it dialed in you'll be able to tell the true hp by using the fueling table. They're normally pretty close to the real thing.

No extra money here just the engine came with one intake and carb. then got the B2B Fast and decide to get the XFI. I traded for some of the parts.
I'll use the 42's I'm not married to the 50s.
