halfafish and three quarters of an engine, what is this, public school math?
He is only showing 1/2 of it. Kim
Haha, very clever sir. I can make this a school math problem!
If Jenny has three apples, how long before sundown does she need to close the windows before before the train with three dogs from the opposite direction serves dinner?
On a clear day it would be only 17 minutes and 41 seconds, however if it's cloudy that changes everything, then it becomes 11 minutes and 9 seconds.

Who said a 340 had to be Orange, Blue or turquoise? I decided to gloss black with stainless steel bolts.

This is the LA 408 in my '62 Valiant V-200, which I've never really gotten to run right since we could no longer get 93 octane gas in California. It's supposedly got 10.5:1 compression with open-chamber heads and a Comp Cams 246-degree cam at .050. It detonates quite a bit on the 91 octane, so recently I've only been driving it around town easily a little bit, with the vacuum advance disconnected, and have been driving my other Mopars instead. Hopefully the TRW forged pistons haven't been damaged by the detonation. I did a cold compression test recently and all cylinders were around 155 lbs., so I'm thinking it is probably OK. I'm not even sure what the combustion chamber volume is, and I suspect that I have about zero quench with these heads. I need to do a custom advance curve, pull the heads and CC them, see where the pistons are with relation to the deck at TDC, and maybe buy some closed-chamber heads, depending on what I find. But I have two other restorations in progress and I need to rebuild my tractor's engine before I can get to it.

..you said "member"...
Slowly nibbling away at a '70 340 to go into the '72 Duster 340 in the background. Working for a living and a broken right hand has slowed me down considerably but I have what I need to get the cam & timing chain in. Except time...
