I'm installing the engine back into my '62, 340hp. I primed the oil approx. August of 2002(5 months ago). Should I reprime it since I had to wait so long before preparing to install? Thanks for any help.

I would. Why take a chance? -
Re: Priming oil in new engine.
You can do a cold crank prime using the starter. When we replaced the oil pump in my 1979 last summer, we disconnected the hot wire from the HEI distributor and cranked the starter until pressure showed on the dashboard oil gauge. The replaced the hot wire and fired up. Worked very well.Comment

Re: Priming oil in new engine.
Don - it is important on a NEW engine, with a flat tappet cam, to spend as close to ZERO time below 2000 rpm until the cam and lifters seat in. This includes cranking the engine without running. I would use a distributor type priming tool right before I fire it up. Run it with a drill to reach 50 psi or so for a minute. I have heard rotating the crankshaft a turn, priming again, then one more time, is good as well to get the oil in all the lifters and pushrod tubes. Then light it up, bring it immediately to 2000 rpm or so, and vary the speed, don't leave it at a constant rpm during the run in. Don't use any synthetic oils for 6000 miles, and change the oil and filter after the run in to remove the break in lubricants used to assemble the engine. Enjoy your new engine!...CraigComment

thru the bowl vents so the engine lights up quickly.Comment

Re: also fill the carb float bowls
Good point Clem...I also like to run in my new cams with the outer springs only, then use an on head valve spring compressor to install the inners, just to keep the pressure low on the lobes during run in. Kind of a pain, but, worth the hassle IMHO...CraigComment
