1.Engines and Transmissions
There are many available engines out there, ready and willing to be put to the test in your truck. The engine you choose will have to be matched to a transmission that will function properly with the new motor. The most common engines used for these conversions are the 350-cid Chevy small-block and the 302-cid mustang motors. JTR likes to use the '88-'92 Camaro/Firebird 350 TPI motors for most of its smog-legal engine swaps performed on those same-year trucks. JTR recommends the 700-R4 transmission, or if you opt for a manual transmission, the Borg-Warner T-5. These transmissions and the 4L60-E automatic work well with the Chevy V-8 conversions, depending on the horsepower and torque the engine puts out. Depending on your budget, the engine and tranny will be the main chunk of dough spent on your swap, if you are doing the install yourself. Some other creative engine choices out there are the Buick V-8 engines and the Toyota I-Force V-8 engine. If you can afford a brand-new motor, it might be best to have a crate motor built to your specs like the one pictured here.
