....I don't know how to attach stuff but if you go to www.sdpc2000.com & put it part #89017488 it'll come up. It doesn't have the details on it though. It does have details on the 502 truck crate motor & the heads are the small oval port ones with 2.065 intakes & 1.725 exhaust valves. The cam's duration is 204/209 @ 1/2" with 4.80/4.83..... REALLY small..... Bill
