Since these engines are no longer used, the problem is the aftermarket performance bolt on parts. If you have the money to swap to a Chevy engine-then go for it, because you then have the ability to upgrade parts, there are stroker kits available for the 350-you get the idea. All we [PRV owners] can do with the engine (while keeping a stock look) is replace camshafts, the heads and do some port/polish. You can go crazy and get thinner liners and get custom pistons to get a desired compression. We can also try different methods of fuel delivery-carburetion, EFI, whatever. Ultimately, it will be tough to get considerable gain in HP without a turbo kit. So you're either stuck with stock and 130, or you've got up to 190 using DMCH and their methods, you go with a different engine or you spend the money on a turbo. BTW, you guys think 6K for a new performance engine for the DeLorean is bad? You should see how much it is to just buy a muffler-let alone a new performance engine for a Lamborghini is! -----Dani B. #5003 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
