Vette(s): 1972 Coupe Anything, but Stock and more mods to come! SSBC Force 10 Brakes, 3.73, TH350, 355 CID, Rack and Pinion, Vette Brakes suspension front and rear.

Weiand has two new intake manifolds out on the market, that make kick butt power over the edelbrock piece and should fit under the hood fine as they are much shorter then the edelbrock piece and not much taller then the 8004 Weiand that VNCRUISER is using.

here is a link to the dyno chart. While this is for the Vortec Heads the same runner and flow design is being made into a standard head version as well.

http://128.121.65.5/data/Products/Media/8121_Power_Curve.pdf

The part numbers are: 8121 for Vortec and 8120 for Standard

Overall we averaged 25 more HP and 25 More Ft Lbs across the entire power curve. The guy that designed these is a guy that we hired a year ago that was Edelbrocks cheif manifold engineer. We bought him some new state of the art design and computer air fuel flow annalsys software and so far the results have been outstanding.

I believe the Weiand out performs the Performer, fits under the hood, run one on the L-36 car, runs great.

Vette(s): 1979, Targa Blue (72 Color), Pace Car rear spoiler, L88 hood, Dark blue factory interior, 525HP 406, HD 700R4, 370 gears,Steeroids, composite rear spring, TT IIs wrapped in T/A Radials.

I put a performer rpm on mine with a drop base and a 2" tall k&n. Probably 1/2" to spare with the stock hood.

Runs great. Although I'm using an Edelbrock carb. Depending on how much cam you have, the regular performer may be the way to go for 30-40 bucks less...

Good Luck!
