   1.42 hp/ci is reasonable IMHO.

The real issue here is the uncorrected horsepower and torque numbers.  At 12:1 compression, and iron heads, it is just a guessing game.  Joe-JDC

Gotta run the plugs in and put wires on.  That's about it.

Spent yesterday grinding on the pushrod tubes.  My valves are taller than stock and I had to shim the rockers up .120" to handle it.  It pushed all the pushrods up in the very corners of the pushrod tubes and I spent probably 3-4 hours yesterday just grinding.  Ground through on one intake port, had to epoxy and get back at it. 







Here's where I ended up on rocker arm geometry.....very pleased with the new rockers.

That....is a very nice contact pattern. Good looking engine too, but I think you could put a tunnelwedge on a greasy stock 360 and it'd look bad to the bone ;)

Is that a Powerbond balancer?

Tunnelwedge or really any dual carb setup looks awesome to me.

That thing looks GOOD. I don't think anyone would complain about that sitting under the christmas tree! Can't wait to see what it does.

I’m curious where you got the 2x4 linkage. I haven’t seen it plated like that before. I kinda like it.
