Re: [Chevelle-list] 402 BIG BLOCK WITH 6 SPEED 90'S Z28 TRANSMISSION-

Hey Steve, You can certainly make this swap.     I can get you an adapter plate and custom pilot bearing that will allow you to bolt the 6sp right in place of a Muncie 4sp.  You can even use a stock bellhousing, flywheel, pressure plate, throwout bearing, fork, linkages, etc. You would need a 26 spline clutch disc. Other things to consider include;  either an electronic speedometer, or a pricey electronic-to-mechanical conversion box. Move your crossmember rearward 3-4", shorten your driveshaft 3-4",    and some tunnel modifications.  Here's some pics to show you about what  you'll have to do for a 5 or 6sp TREMEC trans. http://www.5speedTransmissions.com/tunnelsurgery.html And your shifter location will be significantly farther rearward that what you have now, so bucket seats are a must, and use of your console becomes questionable. All 3 items above would run you about $765, so it's not a cheap swap by any means, but can be done. Be leary of the '93 and early '94 T56s, they had a problem that was corrected in mid-'94.  The '98/'99 T56s have the farthest rearward shifter location.  Here's some shifter location details:   http://www.5speedTransmissions.com/6_speed.html Andre's right about watching your gearing.  You don't want to get too tall of gears.  Here's a calculator to play with: http://www.5speedTransmissions.com/gear_calculator.html As a side note, the Viper T56s are no longer available in the aftermarket.  Once all the vendors sell out, you'll have to go to Chrysler to get one, and they are $3600-$4000.   Apparently Chrysler used the big stick on all of us....
