Re: need help

You need an adapter for a carb intake. Holley and Edelbrock sell direct replacements(TBI).

Re: need help

The pic you showed is only a bit better than stock. Holley is good to 6500 rpms so they say. My Holley has seen 6000 rpms but it or my 7.4L TB(with inj pods) is a slight restriction.

Re: need help

Summit maybe sells the adapter. I bought mine from Howell Engineering but never used it and returned it. It was .50 inch thick and 2.00 in bore.

Not sure on stock hood. you would need to measure with play dough or modeling clay. I went to Howell since it was a 2.00 bore and .50 inch high. I also owned a single plane that was machined down to minimum for more clearance(vett hood). Never used. Now I wish I had given it a try and had it machined for port fuel.
