Now I'm gonna let you finish, but look into a LSx swap if you're seriously thinking of the n/a/EFI/smallblock V8 route. By the time you add it all up you'll be out the same money(maybe less), have modern EFI that will drive outstanding, make a good honest 400+ rwhp at a reasonable rpm, us mostly OEM parts, save a ton of weight, and fit better than a 351 under the hood. Just dropping a turd into the punchbowl.

I wished that the LSx swap was as big a thing around here back in 2007/8 when I dropped $10,000 plus into my Dart big bore. I would have gone LSx turbo instead in my 1995 Cobra vert and been out half as much as I am now. Maybe even had it running too. lol

Doug why the thought of ditching the turbo? I have thoughts of buying a chassis and building a drag car and putting my Cobra back to stock myself. I just miss driving it and there is no way I can sell the $30,000 in all brand new parts I have. Might as well buy a rolling chassis in great shape for $3,000 and send it to JamesB for the the street car works. I figure for $10,000 or less i can have my convertible Cobra back to a driver and a badass street/strip car also.

Damn! I wouldn't have thought it would have been that high. It's got me rethinking what mine might put out.

keep in mind most people with 408w's dont use a t5. so there is a lot more parasitic loss from other trannys
