Will not work with Gen VI engines. Weiand
does not recommend using a Supercharger
with a Gilmer-toothed belt and pop-off valve in an enclosed engine compartment. There is a high risk of explosion in the event of a backfire. 6-71 Superchargers
are perfectly suited for engines with 7.5:1 to 8:1 compression ratios but may require race gas unless Pulley
ratios are altered to reduce effective compression ratio below 12:1. Weiand
recommends that all kits use double keyed crankshaft and double keyed, steel, SFI approved balancer. Kits include manifold, blower assembly, drive snout, pulleys, belt and hardware. Will not fit 8.1L (496 cu in) or 7.4L Vortec big blocks. Big Block kits fit standard deck motors only. Spacers are available for tall deck engines. Due to the wide variety of installation possibilities, it may be necessary to consult with a Weiand Supercharger
