If you've tried to exchange that slushbox for a stick, only to be told "No" by the better half, then you're doing it all wrong. Just be sure to remind her of the extra coin you'll be saving with the increased gas mileage from lower-rpm cruising speeds. Of course, in reality, we're really just jonesing to bang the gears and scratch the tires at every opportunity. Now if you're wondering why we aren't keeping the four-speed, the short answer is that our projects are not "collectible" Z/28s, Yenkos, or other limited-production models. They're actually being built to be driven, so why not have the best of both worlds? Of course, swapping over to a manual transmission isn't particularly difficult. In fact, the real challenge comes from gathering all the parts in the first place. Considering we had two projects tossing the factory four-speed Muncie-a '67 Chevelle and a '67 Camaro-in favor of a Tremec overdrive five-speed transmission, finding a complete swap kit was key for a trouble-free installation. Our choice was Classic Chevy 5-Speed's TKO-600, which is offered as one of the most complete conversion swaps on the market for both vehicles. The Classic 5-Speed kit features a McLeod flywheel, clutch, pressure plate, and scattershield for the LS2 mills we're using. The complete hardware package for the conversion includes a new crossmember for the Camaro. (The stock crossmember in the Chevelle works for the swap.) While stock mechanical linkages and pedal assemblies are offered, we opted for the hydraulic-clutch conversion kit. Follow along as we show you the ins and outs of a complete Classic Chevy 5-Speed conversion.  The LS2 going in the Chevelle...  The LS2 going in the Chevelle is the new GMPP LS 364/440 crate engine (PN 17802134) rated at 440 hp. It was obvious that a great First gear and an economical Overdrive gear were necessary to provide quick launches plus pleasant cruising. Since the LS2 comes with an automatic-transmission flexplate, the first task was to remove the flexplate and mount the McLeod scattershield and flywheel. Bobby Livengood of Livengood Fabrication in Landis, North Carolina, attached the scattershield mounting plate and was in the process of mounting the flywheel when we discovered that the oil pan was interfering, precluding proper attachment.  Measurements were taken, and...  Measurements were taken, and a little assistance from the plasma cutter and grinder took care of the fitment issue. McLeod is working to ensure that its scattershield will fit most LS-series engines and original or modified oil pans.  Our experience with the Chevelle...  Our experience with the Chevelle paid big dividends when we unwrapped the Turn Key Engine Supply LS2 that'll end up in the '67 Camaro. Livengood quickly removed the flexplate and set up the scattershield for the proper cutout. Since this oil pan is different, additional material had to be removed to allow the mounting plate to sit flush with the block.  The McLeod flywheel, pressure...  The McLeod flywheel, pressure plate, scattershield, and transmission adapter plate were quickly installed, and all bolts were torqued to the specs in the easy-to-follow instructions. A clutch-alignment tool, included in the kit, ensures that the trans will slip into the pilot bearing properly.  The next step in the instructions...  The next step in the instructions (you know, that sheaf of papers you tossed in the box!) guides you through the simple process of attaching the hydraulic throwout bearing and determining the proper length for the throwout-bearing piston. We removed the stock input-shaft support sleeve and prepared the surface of the slave cylinder for mounting. It is important to ensure the bleeder line is on top of the slave cylinder.  At this point, the instructions...  At this point, the instructions direct you to take two measurements: one from the face of the clutch fingers to the aft surface of the transmission/adapter plate and one from the face of the transmission to the surface of the throwout bearing. (Make sure the bearing and sleeve are fully seated.) The tolerance for the slave cylinder to work properly is 0.100-0.300 inch. CC5S will send the proper-length sleeve if your measurements are outside this range. The sleeves are supplied in 0.200-inch increments and we were able to achieve 0.125 inch clearance on both transmissions, well within our window.
