professional looking. Additionally, when I dropped off the Vette at Big Hemi - Jason 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 Big Hemi. 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. I’ve include an assortment of pictures that you may use as you may see fit.
