H-I-J '76 Nova re-fit.

I fully realize that I have no skin nor treasure in the project that Todd and Autumn have shared.

However, when it comes to some technical items and issues, I think it is necessary to make those issues obvious before one goes down a problematic pathway that may be paved with lots of "he said, they said, everybody knows..." kinds of guidelines.

For a SBC (2.45" mains, 2.1" rods) with normal racing clearances, it is worthwhile to note the resultant internal oil leakage sources.

These data are as listed from items indicated:
Lifters (16) = total diameter of an orifice = 0.2323"
Cam brgs (5) = total diameter of an orifice = 0.2369"
Rod brgs (8) = total diameter of an orifice = 0.2899"
Main brgs (5) = total diameter of an orifice = 0.2476"
Will leave it to others to evaluate what those orifices flow in gpm at various pressures. It is quite eye opening!

Anyway you might look at it, that is a lot of leakage when you consider whatever psi one might want to evaluate. A builder is logically charged with the responsibility of how much and how to control the leakage paths. Sorry for the brief hijack of this otherwise very interesting thread.

Tie that hair back!
She may not be running the machine; it's just a great habit to be in.

She doesn't have safety glasses on either. She also rode in the back of a pick-up last week. Can't tell these crazy kids anything these days!

Stocker Stuff! Autumn got the rods numbered, bearings put in and ready to check clearance. Measured the deck, got the crank out and back in the balancer. Autumn was busy today so I went at it alone and started squaring up the deck (made me video it so she could watch).

Actually not funny. These habits, or lack of, put me in the ER with a metal chip in my eye.

Seriously you guys need to f-ing lighten up! Someone without their hair up, safety glasses, knee pads and a helmet screwing deck plugs in a block and it's like we're doing donuts in a daycare with a dump truck. I think I need to put myself in time out for a while... this place is a nice reminder why I don't hang out with up tight geriatrics on the daily. I was warned about this early on in this thread by people here in the builds section, I think I need to put this thread up on blocks for a while!
