Bill, I agree with the others on the dual pattern cam too....it's just newer technology, that's all. They work better in all aspects than the older, single pattern cams. And you will not lose any tq or hp. I would stick with the 238/244 you mentioned. If you want it to sound a little 'nastier', get it on a 108 LSA. You will lose a tiny bit of vacuum, and it will move your tq peak up slightly, but only like 200 rpm or so. Try it in DD and see. But it will get you up there quicker, you will pick up a bit in tq. Try a couple other cam companies too, it cant hurt to ask questions. I like the vodoo cams from Lunati. Also, Howards Cams is a great company to work with. Small, only a few guys in the shop, and they actually do the grinding and building of engines right there...so they're not just looking at a computer screen and telling you what the software is suggesting. Call 920-233-5228 and ask for Scott or John. They will take good care of you. Better prices too, cause they dont pay for all that advertising all the time!!
