Please Learn from my experience with a Chevelle I bought a few years back.

Engine had 800 miles on rebuild, looked great on the builder's invoice, SpeedPro stock 11-1 forged pistons, ARP bolts in re-sized rods, balanced, new vales and guides etc.

Oil came out looking like liquid graphite, sludge in filter. And pan. UH OH!

Bearings were down to base metal, crank had grooves, five rods out of round, loose valve guides and grit everywhere.

After a back to basics rebuild put up great numbers on the dyno and break-in oil came out clean. Runs great and runs to redline with confidence.

Save your nickels and dimes, get a competant engine builder involved, no short cuts, and it will be good for another forty years!

There we see the problem and my biggest fear. I never hear anything positive about any machine shop or builder, and when I do, they're halfway across the country and or have a year long waiting list.

From a previous post "The fella who built it also said he'd gladly help rebuild it so that'll be cool!"

Is that not a viable source of help anymore ?

I forgot, honestly. Yeah, I need to reach back out to him.

I pulled the timing cover. The cam is not a 305H, it's a 300H. Much, much milder than I thought. Compare this to the 305H's .575 lift and .253 duration @ .050 and a 110 LSA versus the 300H. It doesn't look like this grind is available anymore, either, so I'm not 100% sure what I want to do.

That looks like a nice street cam. If you can swing it, a roller conversion would be the best insurance against cam failure again. I'm sure there is a cam that is close to, or a copy of, this grind, If not others have called Erson cams and had one made.

There's an NOS one on eBay and I'm really, really tempted to pull the trigger. I'd imagine a vintage, never used one would help circumvent the issues going around with softer cams, no?

Does the NOS cam have original packaging with a date produced on it ? If it's from the 80's or 90's, one would think it was a better quality product back then.

I can say with confidence it has the old Competition Cams box instead of the reds and white COMP logo.

I hope links to it are okay (and please, y'all, don't snipe this from me ��)
