Stroker Motor

AirForceAngler · November 22, 2001

Has anyone ever heard or read about someone building a 383 stroker for a newer (old body style) Chevy? I'm thinking of building one for my '99 Tahoe. It has to be able to work with the computer and stock fuel injection and all of the other stuff. I realize that the computer will have to be remapped and I may have to go to larger injectors. I'm doing this because I sold the 458 that I was building for my drag car!

sounds like quite the project. The 383 stroker is a nice engine. I haven't heard of it being put in a newer truck, but I'd love to see the results. that's a big project.

The 4.8/5.3/6.0 motors are almost completely interchangable and the 5.7 genII is nearly the same. A 382 (6.2l) would be close to the 383 stroker and is attainable through all bore or a crank stroke change. Power is definately good with the all bore 382 but a stroker 382 would produce more TQ at lower rpm. Programming would definately be the key to making a project like this work well in a daily driver use configuration. If your willing to sacrifice drivabilty for HP these are esly upgrades but you will sacrifice a good 10-15 % power potential.

I'd highly recommend going with a Whipple, headers, exhaust & a Hypertech (raise rev limit, set shift points, etc...). It'll cost less than doing motor, & provides impressive power.

I had this exact combo on a 97 4x4 tahoe, it ran very strong & was all day reliable. I actually set the Tahoe up for my (now ex) wife's daily driver. She loved it! Don't remember exactly, but seems everything was under $7k installed.

Otherwise, you're looking at building up a new motor, & getting the computer reprogrammed. Ed Wright @ http://www.fastchip.com/ can set you up with a custom program. Depending on how fast you want to go/spend, 400+ cid shouldn't be a problem & will boost low end torque that much more.

Lingenfelter, aka LPE built 396 cid motors for some Tahoes but price was major 1$,$$$. http://www.lingenfelter.com/

Hope this helps!

Thanks for all the inputs. Especially on where to get custom computers. I know that this will probably cost more than the supercharger route, but I want that stock look and dependability. I've heard stories of some of these superchargers causing early head gasket failer, did that happen to anyone?

Another reason for doing a whole new motor is that hopefully I can pick up a spare engine sometime and just build it up when I have spare time and $$ then when it's all done, just drop it in with a new computer. Less down time involved.

Hey, maybe if this works well, I'll start making this a package for other folks and get into business like Lingenfelter! Man, wish I could afford something of his!
