TBI spacer plate: BBC or SBC?
I'm thoroughly enjoying my recent return to hotrodding and cars (after a 20 year racing hiatus) because of this site! There's literally TONS of incredible information and super knowledgeable folks!
I recently picked up a 5-speed 1989 convertible RS now with a 350, mild cam, and Hedman shorty headers with 3" Summit exhaust. According to what I have read, this will 'wake it up' a bit. I just had the 46mm throttle mod done and I have the 3704 Edelbrock coming - then heading to the machine shop for boring of the holes to match.
My question is: Can I use a BBC throttle spacer from Spectre with is already at, I believe, 52mm, or should I get the SBC spacer and have it bored out to 46mm? I NEED the spacer (NOS plates made for TBIs are like hens teeth!) as I'm using one of my old NOS systems laying around. I'm going with 2 fogger nozzles screwed into the spacer at 75 HP a piece.
Also, will I be able to close the hood with the 1" spacer and a Summit 3" x 14" in diameter open element air filter?
Any help would be appreciated!
