I took another look at the rules and it looks like 2250# would be minimum weight for a competitive 18 degree, sheetmetal tunnelram w/ 2 carbs. 23 degree head would save 100# but I don't think it would be a good trade off. Now find you a GOOOOD head porter. If the heads won't kick ass you're fixin' to waste a bunch of $$$. Put this thing together using all the latest technology (dry sump, big cam, slot lifters, light rods,light pistons, etc.)and get ready to turn it 10,000 rpm. Put it in a GOOOOD car on a short tire with a steep (5.71+) gear and hang on. It ought to be competitive, it might even win, but it's gonna love valve springs and its probably going to want rods, pistons, and rings every 100 runs (we changed every 50 or so in Pro Truck). By the way this ain't no cheap motor in case you ain't figured that out yet. Good luck and see you at the races.

[> Ok so I didn't read the rules al the way to the end... And I agree they would be some valve spring eatin rascals. Just another question though since there is no cubic inch limit. would it be feasable to build more cubes there by lowering the 10000 rpm needed to make that power? -- Bam-Bam, 04/24/07 12:30pm
