Dwight Simon, 71′ Corvette. My happy story.

After researching the various 5 speed companies offering a C3 Corvette conversion kit from an automatic to a 5 speed I choose Keisler Engineering for three reasons. 1. After a couple indepth conversations with Gene and Jeff at Keisler Engineering, I became convinced they offered the best COMPLETE KIT product. 2. ALL the parts required to change out my 700R4 trans to a five speed came in one kit. 3. Gene accurately recommended a competent local installer called Midwest Customs & Chrome in Ft Wayne, In. At Midwest I spoke with Todd and became convinced they could complete the swap easily. Previously, the 454″ small block from World Products was dyno’ed at the rear wheels with at 376 HP and 412 lbs of torque with the automatic. Gene suggested the TKO 600 with a 0.64 5th gear as the vette’s rear end is 4.11. He also helpfully suggested a few additional parts to really complete the install such as new tunnel insulation and new manual shift plate. I had The 5 speed kit shipped to Midwest Customs whose crew did an outstanding job of making the swap. Attention to detail was super. By that I mean they repainted the shifter console and also fabricated new console support brackets making the install very professional looking. Additionally, when I dropped off the Vette at Big Hemi – Todd suggested swapping out the Holley carb for an EFI unit because of the cam overlap and idle problems I’ve had. Long story short – I purchased a Powerjection III EFI from Summit and had it sent to Midwest Customs. They installed it easily and it runs real well. The trans allows me to cruise at 70 mph at 2100 rpm while the EFI makes the motor have civil street manors. I especially like the smooth shifting trans, zero vibration and stock looking shifter. I would strongly suggest the Keisler trans swap to anyone wanting to upgrade their pride and joy.
