The 268 at .050, .540 lift juice cam from the eighties was as wild as you could get. It is no longer listed and people at Comp don't remember it. Anyone have detailed specs for this cam? A friend has one in his 68 roadrunner and a couple of lobes and lifters failed. We want to replace it with an equivalent solid or hydraulic . The motor is a lowdeck 451 stroker using kb hyper pistons with the raised area for quench. The heads are from McCandless as well, the iron 452 heads he used to sell with just a 70 degree plunge cut and 2.14 x 1.81 valves. This motor pushed a FULL WEIGHT 68 roadrunner to 11.27 with closed exhaust so it sure did punch above its weight! So, looking for lsa, duration at . 100, .200, etc to try and match this cam and maintain or increase hp.

I’m pretty sure it was just a 21-320-4.
Lobe number 5196, single pattern on a 108.
There should be some numbers on the old cam when you take it out.
I’m pretty sure I saw someone selling one of these over on fabo.
Edit- I was wrong....... the one for sale over on fabo is the next smaller one........260@.050

Thanks , Bird, Dwayne. I used that cam in my Dart with a 475 cube motor, 440-c heads bowl port only, 12/1 compression, 750 methanol carb, 3180 lbs. Best of 10.10 at 131 mph. It impressed me as being pretty good. I look back and that is where i should have stayed!

You Might try to get a hold of him thru his son Mike maybe thru Facebook at McCandless Antique Auto or catch him at one of the shows as i hear he is very polite and loves to talk Mopars for sure. I have seen him out at a few down this way and his son will try to get an answer for ya i am sure. https://www.facebook.com/McCandlessAntiqueAuto/?ref=py_c
