P-51 headed 472 build... DYNOED

Finished assembling my short block last night.
Thanks to Lem for the speedy service for my Diamond pistons, rings, Kaase oil pump, P-51 heads and Cometic gaskets.
All sent via USPS... 8 days from Kentucky to Calgary and the heads missed customs so no handling fees or taxes
Thanks to Ron at Custom Balancing in Balzac Alberta for balancing, piston pin and bearing clearances, and file fitting my rings.
Just have to get my cam degreed.

Welcome to the P-51 family!!

Thanks guys. Lem, how much torque do I use to install the rocker studs?

65 lbs ft

Good deal Ken. Steppin' it up a notch I see.!









Doug...

Thanks Gents
Sooo... ever take one step forward and 2 steps back
After I bolted the pan on last night I rotated the crank and it stopped with a thud
The culprit, a rib on the back of the Kaase pump hitting the front crank c'weight:


Nothing a die grinder couln't fix:



Got the heads torqued on... resting my arms now

I noticed there were no piston valve cut outs for the exhaust valves. Is this normal with P51 heads? What v/p clearance did you have?

I had the plasticene rolled into 1/4" ropes and the valves barely marked it.

That's normal, no exhaust reliefs needed.

YEP! It's not a big deal, but I would think as many that have to modified (all that I know of) they would make a "slight" alteration in the casting. Like I said though, it's not a big deal to just grind it off.
