Doug, I don't know if you read the description of the engine in the vid, but this is interesting: "... the camshaft was ground with a 113-degree lobe separation angle and 242/248 @ .050-inch-lift duration numbers. Rabotnick was unwilling to disclose lift numbers, but we can say that they are ‘healthy’."

I saw it. I'm going to change out the cam. Brent's going to do a custom grind (we haven't talked about what yet). My Holman Moody "B" cam is in great shape so I may sell it along with the Lemans rods and TRW pistons.

I think that's a good plan. Post the specs when you decide on them. |

Humorous.  Note that the duration and LSA Barry chose for the cam in that vid are pretty darn close to my 54 year old "K" cam. |

That's beefier than what you've got now. The "advertised duration" of your current cam is 324 degrees (IIRC), but they measure it from a different spot, so you really can't compare it easily. The .050" numbers are significantly harrier than 245/245 106 LSA and .500" lift after your lash is taken out. |
