NY Heavy Duty TBI Adapter To Square Flange

[Upstate]

I got a heavy duty Holley adapter #61R-671B TBI adapter, not one of thin adapters that will warp. Has less than 15 minutes on it. Put it on to sell the motor. Bought it new from Summit.

$50 plus shipping. Comes with the factory/correct bolts to mount to square flange intake. Had it on a Edlebrock RPM manifold.

This thing is like brand new $40

Is the TBI flange for SBC or BBC? GM used two different bolt patterns for TBI's.

To the best of my knowledge the only difference was the size of openings or 1-11/16" versus 2" on the big block. I had a BBC TBI on there with no issues. It was a modified one though. Are you thinking that the bolt pattern is different also?

Yes the three hole bolt patterns are different between the two and I want the BBC pattern.
