Not that I believe much of anything coming out of TBI Chips verbiage, I ran one for a while, I think he's saying you'll need more flow than a "stock" TB can handle. If you wanna rev it up to 5400 RPM (2200-5400 cam as advertised by Elgin) you'll need a bored out TB or even go to a 50mm one from a 7.4L and bore the intake to accept it. I have a 46mm TB (650 CFM advertised) with the Edelbrock 3704 intake bored to 48mm running an 18 LB spring set @20 PSI.

The "stock" distributor will work fine, with tuning both fuel and spark tables. YMMV

Did u port the intake yourself? I found these guys at spr that sell 46mm ported tbi so ill be getting that. Also the 3704

I bought the same 46mm from SPR too with an 18 LB spring. I added the VFPR from RV Morse machine before he passed away. There are other sources out there. I see the price has gone up $26 since I bought mine.

I took the 3704 to a machine shop and had it bored to 48 mm, cost me $50.
