No, I'm not talking about a new girlfriend who can suck start a big block Corvette.
I'm talking about a carb spacer that has horsepower and torque gains higher than I've ever seen. Apparently, the 1" spacer provides a 15 hp/10 lb-t gain, and the 2" spacer provides a 22 hp/20 lb-ft gain. Super Chevy magazine, in the March 2002 volume (sheese, it's only December!) tested a 1" Super Sucker carb spacer, and on the dyno they witnessed it actually providing a 14.9 hp and 10.4 lb-ft gain, exactly what was advertised. Which is kind of rare.
Probably not many of us can do a 2" spacer in our tight Corvette engine compartments, but with a drop base air cleaner, a 1" spacer is possible. The spacer is phenolic, and is machined out of a type of plastic, that apparently doesn't melt at engine temps. Plastic IS a pretty good temperature insulator. So I'm willing to give it a try.

I think if you are turning enough R's it's for real. A very good friend had a 355 13:1 hot rod motor built for his '85 track car. The builder dynoed it with and without the spacer. 19 fwhp for real. That was at ~7400RPM.
Re: How 'bout a "Super Sucker"? (yoslambo1@cs.com)
will you have hood clearance problems on a c-4? :confused:
Only works with carberators, won't work with your LT-4 (psudo-Grand Sport in your signature).
Although if you really just had to add spacers you could probably add about 4 to 6" between the throttle body and the intake without too many modifications.
sorry no pictures (on computer only regular photos). the crossfire is coming out. i have a 383 stroker on the way & im gonna go carburated(holly 750). thanks for the compliment. i wish i could keep my air cleaner. it looks so sweet. im gonna try top fabricate it to fit over the holly. :yesnod: :cheers:
