371 build W/Big Mouth heads

Well a little update is in order: Broke the cam in this evening with the outer springs only for a total of 20 mins. No oil leaks which is nice and really nice oil pressure- 40 psi@1000rpm 60-63 psi@ 2500rpm and up hot. Checked lash and nothing out of place there. Tried two exploratory pulls from 3500-4500 and 3800-5000. Wow is this thing cammy--falls into a hole right off the brake and takes off when it hits 4000 rpm like someone hit the N20 button. HP curve is quite steep from what I can see so far.

The plan for tomorrow is install the inner springs and find out what's what. Timing is locked out @ 35 and I can already tell this thing's gonna need a timing curve shaped like a banana.

Very interested to dial this in and if it shows promise I might order another custom cam and install it right on the dyno cart ASAP. J.Rob


Can you remind me what cam you have now.

Since I'm not spending my money, of course I'm going to say hell yes slap another cam in there whilst you are on the dyno.

When I'm spending your money I spend like a drunken sailor. No offense to all the navy folk out there.
