351m cams?
I am looking at two cams summit racing offers, but I wanted input from you guys on which cam y'all use. Any mods to the engine, cam profile and how you like the cam over the stock one.

do y'all have videos of your idle with the 5200? How much power do think it added? I already have a holey 650 carb, rpm performer intake and long tube headers on it. Thanks for the timing chain reminder! I planned on this years ago then life got in the way and I completely forgot about changing the timing chain

Bck in 1987 I put a Crane Fireball Cam in my '77's 351M, used new lifters and the rest of the valve train is OEM stock stuff. The cam is no longer made by Crane as far as I know, but I have the spec sheet on it and it is exactly same as the Edelbrock # 2172 which reads same as the Summit # SUM 5200. With a new straight up / adv timing gear & chain I installed, it did perk up from the oem cam as I recall.
It's likely not seen 5,000 rpm more than a couple three times (not recently either) as I am not hard on it and I've done bearings once at 75,xxx .... about 30K ago.
