Best underdrive pullies for C4
I am looking for the best underdrive pullies for a a C4. I found these http://www.madvet.com/shop?frame=3.141.844 and they state 12-15 rwhp increase.I am sure these #s are for a stock Vette. Does anyone know of a better set? Thanks!

Anyone have a part number or link to a set for 95. I can't find them. I see them for the firebird.
Thanks

You might want to look at ASP in Texas. If they don't already have it they can make anything you want and the prices are fair with great shipping and phone help. We have a set on a 89'L98 block and no problems what so ever.

I believe ASP is your only option for a new set.
This mod is worth about 4hp on a stock LT1, as the waterpump is not belt-driven.

Unless the Firebird and Camaro pulleys will fit that are listed on the website for March. Summit also has the LT1 Generation II pulleys but it doesnt say Corvette only Firebird and Camaro. I will check ASP.
Thanks
Edit: ASP has some. How are theses compared to the MidAmerica pulleys?

i have the ASP crank pulley on my LT4. no issues. the reason i bought it was because my 396 was internally balanced, and it turned out that my stock pulley had an imbalance. as soon as i stuck the ASP pulley on the slight engine vibration disappeared.

Just beware that your alt speed at slow speeds will cause a drain on the battery.
IMHO for street use, go with the crank pulley alone.

The power and amp set has a smaller alternator pulley so that it is unaffected by underdriving everything else.

The alt pulley on a Power and Amp kit OVERdrives the alt to keep output near stock.
The crank alone would underdrive the alt as well.

I got the March power and amp pullys. My amp meter puts out a steady 13.5 volts and keeps my battery charged. The alternator pully is a little larger and the other pullys are 25% undersized. Everything works fine. I put in a new high output waterpump, a 160 thermostat and a new Dewitts radiator.. My ac works great and my Vette runs cool now. I read that some brands are for off road use only but the March series is OK for the street.
