RE: My experience

I have a '69 Mach 1 with 428, a toploader and 3.91 gears. When I rebuilt it, I went up on duration from the Cower 286H that was in it, but was wary to keep the lope separation wide as Royce suggested, and not go to radical. I'm now running a Crane split duration 296H2, which gives 234/238 deg @ .050" and .554"/.563" lift with 112 lobe separation, and degreed it straight up. It's right at the limit for power brakes - my vacuum dropped from 13.5" to 10", but they still work, as does the tilt wheel. It's a great street/strip cam with a stick, idles @ 900, good low to mid range and it screams from 3,500 passed 5,800, but I think it might give someone with an automatic or highway gears some trouble.

I'm using Comp Cams best dual roller timing set and it degreed up first time. The Crower set I took out was 6 degrees retarded, and no the chain was not stretched - it was frigging off that much! So, absolutely degree wheel it, move the sprocket if you have to, take your time to get it bang on...then recheck it yet again just to be sure.

Mustangs Unlimited has trays, but be careful that with the added pan depth with double gaskets that the crossmember doesn't start rubbing the pan...there's only a pubic hair's clearance to start with.
This thread, so far...
