I understand too well. I have often wondered if the Dave was related to Russ over at Indy. Nearly the same attitude. If your spending money, then they are tolerable, but ask questions and I feel sorry for you. Here's one of the HEV6876BS cams. 302/309-270/276 108 Intake events 30/60 Exhaust 69/27. Here's mine Dwayne spec'd, it's a comp. 302/308-270/276 110 Intake events 29/61 Exhaust 72/24. Hughes cams are said to have aggressive lobes causing lobe failures. Mine almost the same aggressiveness and i'm under the understanding my cam is neither aggressive nor tame. Mines still going strong after a couple seasons under what I thought was high pressure for a flat tappet. I'll have to look up the pressures.
