273 Commando Slugs

Pins are lighter too.

Great to see several 273's being built. I wish I would have got the HP pistons strait from Egge, much better price than from Hughes.

I went with comp cams XS268S solid cam, balanced assembly as well, squared the block, stock heads, mild porting 1.84 intake and 1.60 exhaust valves and added a cam tensioner.

Heads have been milled slightly and even with MP .028 gaskets my machinist says I am right at 10.5 compression. Heads are 62cc

I'm interested to see how this thing runs. What car and what trans, rear gears are you running. Should be a screamer.

I wish I had gotten some dome pistons, but oh well, with 9 to 1 she runs good on 87 piss.
