Overkill Cam?

With a 112 intake centreline you'd have +48 exhaust opening and -44 intake closing which are good numbers. I did an XFI cam with 224/236 duration, similar intake closing, had great top end, shook welds loose on the exhaust system but I'd reduce the exhaust duration doing it over again as the exhaust opening was very early and I lost some mid-range torque.

Sounds like the specs off of the cam I bought from you a couple of years ago that you called the BBC Prototype....and, it wins all around. Although, I've tamed the idle, the power band is amazing IMO and I couldn't be happier with my choice.
224/236 duration, 573/571 lift, 115 * LSA

That's the one. Glad to hear you're enjoying it. I ran a 3000 stall converter and 3.69s when I ran it, so torque wasn't a high priority, I just wanted it to run like hell above 4500rpm. I wish I still had a video of it idling, had to take the car to a better exhaust shop, redo most of the welds!
