This speedometer cable is perfect length for this application, turbo 400 in 1956 studebaker golden hawk.

This kit is machined very well, all hardware was good quality. It was easy to install with good instructions, one of them jobs you think might be difficult but speed gems made it easy. Thanks.

I cannot praise Speed Gems highly enough. The kit they sent me was perfect in every respect and allowed me to replace the T85 in my 1921 T Modified with a minimum of fuss, I should add that I am in the UK and, despite the distance, I received amazing product support. Matt Grams was amazingly helpful and understood exactly what I needed.

Everything fit great, only have done the mock up phase but I’m super excited to use the adapter on our SEMA vehicle. I was impressed with the quality of the machining.

The starter plate worked perfect. Good quality good price. I purchased the kit for a customer who had a broken starter mounting pad on the engine block. I had previously purchased a starter plate from another company at the same price and mocked fit it to check for fit and function, the starter drive would not mesh with the flywheel gear. I'm glad I purchased the plate from Speed Gems it saved my customer from having to buy another engine block. Thank You

I am pretty new to automatic transmissions. All my buddies said, no problem Chevy ECOTEC will bolt to any GM transmission. Not so!
Speed Gems Adapter worked perfectly. The cooling system cross pipe, which goes behind the block, is a problem. I am mounting the motor longitudinally in my project. So I'm not going to use the rear cooling tube anyway. I already called in to Thank the guys for the good product.
