I ran that exact cam in my 68 340 barracuda back in the 1990’s with 9 to 1 compression, low first gear 904 trans with a garbage B & M torque converter and 3.55 gears. Used it as my daily driver for many years. Ran hard and had a great muscle car idle.

I ran it too from ‘93 to 2011. with stock 340 “10:1 pistons” , X-heads, HP ex manifolds, weiand 8007 dual plane, stock AVS and 600 Holly 1850 carbs, stock 340 converter, 3.23 gear but short tires.

The 1993 version had 110 advertised centerline. I did not degree it and bolted it straight up.

It’s like one step above stock 340 cam. Performs like small step above 340 stock. Idles step above stock 340. Plenty of vacuum.

Seems doggish down low. Maybe if I had put a double pumper of better carb, it would have helped.

By the MP application chart it’s a 14-13.5 sec 1/4 mile time range.

I think other modern cams would be a better choice. Like comp XE268, or Lunti 268.

I wouldn’t run it again.
