The Big Block Ford to Chevy V8 transmission kit will transform your Ford with many advantages over other options currently on the market. The kit is only 1" thick and made from 6061 Billet Aluminum. This gives you more room in your engine bay and helps to limit fire wall modifications. The kit also requires ZERO modifications to your bellhousing.
This kit uses a factory style flexplate, eliminating the need for any torque converter spacer rings or adapters. This means the kit is significantly cheaper without sacrificing the performance of your build. Utilizing a simple crank spacer retains an OEM style 14.25" flexplate, eliminating the need for additional hardware and reducing potential failure points.. Slightly longer, grade 8+ 7/16-20 bolts are provided that thread into your crank and can be tightened to factory specs. There’s no need to worry about if your engine needs to have a different external balance weight. Simply choose the option that corresponds with your engine and the correct flexplate will be included. (Please note: This will not work with the 157 tooth flexplate.)
This kit also uses an off-the-shelf starter, which means it’s common and easy to acquire, so there’s no need to worry about going on a trip and getting stranded. This will save you possibly hundreds of dollars if this part needs replacement. The kit is designed to require no modifications to your bellhousing. The starter sits inside the GM starter boss, keeping things simpler and easier to install.
