Okay, so I've finally decided to do the M112 swap. Here's how I'm going to go about doing it. I'm going to buy a split port engine, the whole engine, and use the parts that I need. That's how I'm going to drive it for a while. Then, my next step is going to be getting a forged 4.3L stroker set from SSM, ported lower intake manifold, and the M112 adapter kit. Here's where I got to thinking. If the M112 came off of the 03-04 Cobra's... does that mean I can bolt up an aftermarket Cobra throttle body, a 95mm MAF, and have a SVT Cobra Cold Air Intake, as well as this?! http://www.americanmuscle.com/whipple-supercharger-0304cobra.html I'm willing to skip getting a used M112 if I could use that 2.3L Whipple even if it is $4,000. Or, should I just stick with a M112 because the gains aren't going to be worth the extra ~$3,200 (I find M112's going for 800 used). Of course, I'll upgrade the drivetrain, and put in a nice lumpy cam with a nice exhaust set up. Who do you guys think I am not to do that?! Oh, and would I also be able to use any kind of underdrive pulley?
