5 star service. They know Dodge trucks and Power Wagons, first , second and third gens. They know we're the problems are and your truck doesn't spend weeks there guessing what's wrong.

JASPER Engines and Transmissions is pleased to announce that the JASPER 4-Speed Transmission is being used by 28 team/driver combinations in the 2022 NASCAR Xfinity Series season.

This is an exciting leap as the same transmission was used by 12 team/driver combinations in the series in 2021. These team/driver combinations accounted for 19 wins, 84 top-five finishes, and 147 top-ten finishes for the 2021 season.

This is one of many Tremec conversions we have performed. This 6 speed Magnum is going into a tri-5 Chevy.

A very strong 351 based 393cid Windsor we built for a 90’s Bronco. A forged bottom end, a Comp Hyd. roller cam and Trick Flow Maverick heads and rockers. Watch out for a more complete article on this one, coming soon!

A 289cid we re-cammed and replaced valve springs on, in-car.

A 1968 Plymouth 440cid GTX that we rebuilt the top end on, resto style.

Here is the infamous 408 Duster engine we installed for a certain customer. It is a Blueprint Engines 450hp LA small block crate engine the customer purchased and brought to us for install into his 70 Duster. We recommended companion parts to complete the install, such as TTI headers, MSD ignition, a TCI Torqueflight with a proper stall converter. The customer supplied all the parts ( we love that, we don’t have to warranty the parts, worry about shipping time or wrong, broken or incomplete parts. Even though he paid more than it would have cost thru us).
