I'll put a check mark on this one too. P.S. IQ, if you get a set of heads from Merlin, take care of him he is a good frind of mine.

I've heard nothing yet, that I remember, from a Merlin.

Im keeping an eye on this one, should be fun. I wish we didnt live 2500 miles apart, these kinds of projects are fun to work on.

You're right Mike, fun these are.

Pop's 452 heads that he originally built this engine with were using 2.14/1.81 valves and the flows he recorded on the intake were,

.107".........85 cfm
.214".......166 cfm
.321".......218 cfm
.428".......240 cfm
.535".......265 cfm
.645........280 cfm

and in 1997 with the 260H cam it dyno'd 404 HP @ 4800 rpm and 483 lb-ft @ 3400 rpm.

It's going to be interesting to see how it does with the 346 heads with 2.08/1.74 valves that are flowing roughly the same but with the XE285HL cam. The compression is down some now to 8.9:1 with the 346 heads at 94.4 cc's and the pistons with the additional flycut at 7.9 cc volume.

Okay, I'm off to start working on the stock distributor and take out some of that excessive mechanical advance. I just pre-oiled the engine about 30 minutes ago, 80 psi cold with the drill motor.
