Does anybody know the dwell setting for a 1952 8n Ford side distributor.

Thanks, Bob

NAA spec shows 35.5 to 39, I would not expect the 8N side mount to be significantly, if any different.

I've never seen a dwell spec for the old Ford tractors. I wouldn't be surprised if someone has figured it out but I haven't seen it any where.

4° BTDC at 400 RPM...

He is asking for dwell specs

Yep, never have seen any dwell specs... but if so, how does one 'adjust' the dwell by point setting'??? OP MANUAL/ FO-4 tell how to set timing per inspection hole and hash marks on flywheel and timing light. If issues abound, you have other problems; wiring most likely.

Dwell and point gap are INVERSELY related, and more point gap (less dwell) equals earlier spark timing.

Yep, thanks Bob.

Just set the gap. Dwell will follow, as Bruce said. I have seen dwell numbers in manuals for Ford tractors, other than side mount 8N, that are either in crank degrees or mis-print, because too large to be possible. I have also see expressed as a percentage instead of degrees. I have measured both front mount and side mount (OEM & after market) with a degree wheel and with a dwell meter and find disagreement there, too.

Your OEM Operator's Manual and the I&T FO-4 Manual are essential tools. 4° BTDC at 400 RPM seems to sound familiar.
