C3/Dream-machine TRANSformation...

[Vette/Berlina-coupe]

Here's a fabulous website-- http://www.keislerauto.com/gm/transmissions/corvette_68-82.asp --that offers the rugged and fabulous American Tremac/5-speed 100-lb state-of-art transmission which provides a 3.27-lowgear that is the key to moving 1.7-tons of inertial-anchor off the mark in terrific rapidity!! The brilliant website includes an automated-graph wherein you can plug-in your rear-axle ratio and tire-size to find your rpm-comparisons with the old 4-speed gearboxes. The Tremac/5-speed thus effectively greatly increases your wheel-thrust in low-gear, plus the whopping 32%-overdrive allows you to realize low-rpm's in 5th-gear (move stick to the right and then back); Keisler's 5-spd.Kit includes all of the special pieces (Bellhousing if converting from automatic-trans., and mechanical or hydraulic clutch-pedal apparatus), plus they even developed a clever short-throw shift-mechanism (no external-linkage) which places the shifter in the original automatic-lever's console-slot, ---thereby appearing essentially oem! Sure the $2.5k/price-tag is substantial, but its an intrensic-value that's a permanent part of the car (probably increase the car's value $5k), and its a conversion that will make your steed move with the best of'em!! --Am also $aving up additional bucks as to change my '80-C3's 2.80-rearaxle ratio to probably 3.55:1, -because the 2.80:1 combined with the .68-overdrive becomes excessive for no great purpose, when you really can better use the gearing-advantage at low-speeds (thereby also obviating absurdly complex, cumbersome, and costly things like superchargers/turbochargers and their excessive heat problems). KISS (keep it simple stupid) is the engineering advancement behind Keisler's keen retrofit-kit for your nifty C3Vette! Its obvious i am excited about the prospect of making this pre-engineered conversion in the near future, --wonder if anyone here has already installed the Tremac/5-speed by Keisler (they also offer a 6-speed Kit, -but it does not offer the serious gearing-spread advantage of the 5-speed). Please note that while the Tremac-transmission will easily take the torque of a bigblock, it would be sacreligious to even think in terms of hindering your cars handling by also adapting a bigblock, --let the advantageous gearing and high-reving of the smallblock run circles around a cumbersome bigblock...
