BBC Throttle body

Will 7.4 fit on a 5.7 intake manifold? If not then what would I need to do to make it happen?

You have to bore the intake holes for the 2" throtle blades to clear.
There is no TV cable stud on the 454 TBI, I cut one off of a V-6 TB
and welded it on.

Re: BBC Throttle body

RFmaster, can you re-post the pics for the SBC, they aren't showing up. I will be doing this swap soon when I drop in the new 350 I'm building. I would just pop the hood and look at the sbc tbi I currently run, but the car is still in storage (live in Michigan, still snowing out ). Thanks!
