Model T Ford Forum: Forum 2016: Camshaft - grind or not?

I am putting in double nut adjustable lifters and I'm wondering if it is really necessary to send the cam off for a regrind? The car will be a local to show/coffee car for in town use. Local model A guys say NO... just set each valve with the new lifter and it will be 100%.

Thoughts?

Take a caliper to each lobe and measure. You'll soon see if it needs grinding.

Mine did have various measurements on the lobes, so it was a candidate for a regrind. Now at least I know all lobes are identical.

All the best,
Justin

I never use reground cams. The cam controls the engine's breathing. This is no place for a shortcut. I'm a firm believer in the merits of the Stipe .280 cam. The Chaffin's .280 is also a good bet.

check lobes as stated already if they are all but equal just set he valve clearance intake at .012 and exhaust at .014 she run just fine

Had a '27 that ran good but couldn't get a smooth idle. Put in a reground cam from Ford-N-More and problem solved.

Ford did not grind precision cams in the day. That is why they used the piston position system for adjustment in order to get an average lift on all four. Get a modern cam and forget the smoke and mirrors.
