P-51 push rod length- help really dumb question

Post  512Fairlane on April 19th 2015, 1:14 pm

I have a really dumb question but I'm going to ask it anyway because I'm old and forgetful. I have P-51 heads and I run 9.100" and 9.300" push rods. Well I mixed them up the other night and I don't remember which ones are exhaust and which are intake. I think my intakes are the 9.100" and the exhaust is 9.300" but can anyone back me up on that? Are the intakes typically shorter? Thanks.

You would have known as soon as you rolled the engine over and watched the roller on the valve tips. Very Happy There's never a dumb ? when unsure about anything. Wink

The exhaust is the farthest from the lifters also. You can see if you look, it needs to be the longest. You wont notice it until you make a point to look at it.
