Hi all. i have bought a new Lunati camshaft for our 67 442 car i ran my thread last fall with the gear change over from 3.31 to 3.91 results, the cam seems to be the culprit from what i have been told and do believe myself, so in the spring here iam going to put the new cam in i have done this a couple times before, i do run 10w40 brad peen oil in it since the motor has been it it about 800 miles now since new rebuilt, this is the combo i was going to use for breaking it in, 6 pack 30W BRAD PENN GRADE 1 GREEN BREAK-IN MOTOR OIL High ZDDP FREE SHIP
Moly Zinc ZDDP Extreme Camshaft Grease Assembly Lube Flat Tappet Cams And Lifter
Well what do you all think ???

What cam did you get ?

My Lunati cam break in instructions were to use non detergent 30w and run the break in procedure. I added a bottle of GM EOS and used Isky Moly Lube on the cam lobes and lifter bottoms.

Thanks oldcutlass !!

Just curious, what brand/specs camshaft are you replacing? Wipe a lobe or just not streetable? Thanks.

john mann

Kenny, i have the JM 18-20 mondello camshaft in there, there's nothing wrong with it just want a little more umph !!

Kennybill

That's good to hear no lobe problems. Sounds like you're going for the most camshaft without going to full roller rockers. It is a hassle changing a camshaft with the engine still in the car. I've done a few over the last 53 years since the first one. I've used similar grinds, I think you'll be happy with it. If not, some times you have to love the one your with. Lol.
JM 18-20 H 260 266 216 226 .488 .496 112
good luck and let us know if your happy.

1. You need to work on punctuation, capitalization, and sentence structure.
2. I thought Brad Penn was out-of-business. Old stock? Seems like Brad Penn was sold in 2015 and the branding and bottle design was changed. https://penngrade1.com/performance-p...nal-green-oil/
3. Looks like some idiot is home-brewing "moly ZDDP" grease in his basement, and selling the stuff on eBay. I should sell eleven-foot poles for products that shouldn't be touched with a ten-foot pole.
