Promise to post some pics later today. A bit embarrassed about the current state. Have some nice dated wires, but not sure where they are, so put some Accell yellow ones on to get it running. Most of them are about a foot too long.
Missing one of the sqare drive pipe plugs in the front of the intake, so have a big plumbing pipe plug with an adapter in it. Lots of other details way off, but easily fixed.

But... would like some advice. Here is what I built for now. 69 L46 (posted pics of the inside of this engine a while back, really pristine standard bore motor). For those not familiar, 69 L46 has the same crank rods and forged pistons as a 70 LT-1. Just used a hydraulic cam, iron manifold and Q-jet.
Built this one with an LT-1 cam (Federal Mogul), 69 Z high rise and 4053, so it will at least LOOK like the correct motor, until someone sees the HW engine code.

Rigged up the batt and radiator (no front sheet metal right now) with a big fan in front of the radiator. Had already pre oiled it. Started right up and ran for about 10 min at 3000. Would have run 15 min at 3000 (what I normally do) but it started to overheat. Fan in front of the radiator is just not moving enough air. T-stat was wide open and had plenty of water flow.

Here is my question: Is a 10 min run at 3000 long enough for the new cam and lifters? Like I said, I usually run 15 min at 3000 to insure break in.

I have a big squirrell cage fan in the attic I can try today that may move more air. Part of me wants to make sure

My other option is to just go ahead and adjust the valves, check everything over and get it ready to put on the front clip

Sorry for the long post, but it can be frustrating trying to answer a question without enough info, so I would rather err on the side of too much info.

Heading out to the garage right now just to regroup. What a mess.
