transverse engine changeover?

[poprodder]

Does anyone know if I can take GM's dohc 4, which is a transverse mounted engine, and mount it in a standard inline configuration (front to back) for use in a Track T roadster? And if not, will the dohc head fit a standard inline 4 block that does? Anyone...???

Not sure what you mean by standard inline 4. Which one?

The short answer is; anything fits anything with a torch and a welder. You'll probably have trouble finding a longitudinal transmission that will bolt up, but otherwise you're basically looking at fabricating motor mounts and designing fuel, intake, exhaust, and other systems into the new chassis.

What I meant by standard inline 4, was that the dohc is based on GM's "iron duke" 4 cylinder that has been made since, what, 1962 or so. And was the 4 cyl. that gm put in many production cars. My concern wasnt the fab work for the motor mounts and such as much as it was for the lining up of the crank to mate either a clutch or torque converter with out alot of machining adaptors and such or mating it to a bellhousing for an automatic trans. And as far as changing the head over, my concern there was the lining up of oil and water passages from head to block...bolt holes...etc....you know...the little detail stuff that has a tendancy to kill a project. From what Ive been seeing and reading, it looks like Im going to have to go in a different direction. Its a shame since that motor has the old offenhauser look to it and would look classic in an old track style T roadster. Thanks for the reply Curtis...sure appreciate it..

Iron Duke should bolt to the transmission from a 4 cylinder S10.

Did GM make severe enough modifications to the ECOTEC for the Solstice/Sky for RWD such that a standard Cavalier/Sunfire/ION/Cobalt/Malibu/etc. FWD ECOTEC won't work with a RWD transmission?

I'm working on designing a car from scratch, and I want a longitudinal layout with the tranny bolted to the engine, directly behind it.

Are there CAD drawings somewhere on the Internet where I can look up the dimensional specifications of this stuff?

Its all based on but heavily modified. If you have a competent machinest it shouldnt be too far out of the question (tranny). The ecotec head swap is pretty much a no I'm pretty sure- but not 100 percent possative. Pretty much every car on the road is based on the hopes and dreams of the likes of henry ford, but definatly not interchangeable.

I guess the "results to headache" ratio would be more favorable if I just went ahead and got the Solstice/Sky motor and tranny. It's just that these cars are still new, and a used motor would almost be out of the question if I were to go ahead and build a car out of it for my own purposes.
