Oh, and I'll trust Panoz and Koenigsegg vs your assertion that 4v modulars aren't good to work with. They were making 400-650hp with them in 05, lightly sc'd. Now Koenigsegg has their "own" variant of a modular that is a spitting image of fords casting with stronger internals, high flow 4v heads/cams, and 1240+hp in tt ccx-r trim. Just saying. Hennessy has had a bad rep of failures with 1000hp ohv mills but 1250-1500hp tt ford gt's from them and ugr don't have any common breakage issues... Ohv and high boost is not a recipe for longevity.
