I would rather have the 270 magnum for the "muscle car" sound.
The 268 will be a smooth torque motor with a hint of idle.Headers will help it sound a little healthier. I agree and better yet call Tim @ Bullet cams for a great grind for your combo.

I installed a XE268 in a customer's 68 runner that had 9.5 to 1, DP4B with the AVS, 906 heads with standard size valves, factory exhaust manifolds. Took out a 284 Purple Shaft that gave less than 10" of vacuum. The car sounds like a new street hemi used to, has 16" of vacuum and fries the tires with a 3.23 in low gear when you mat the throttle. I installed it straight up, no cam advance.

I have ran the 268xe in my 440 for 2 years. Love it. Great driveability, slightly lopey idle and like Transman said, nail the throttle, and it cooks the tires. I am installing the freshly built 440 I have been working on for my swb D150 and it also has a 268xe. Stock converter works well, as do power brakes. I've had other cams in 440s in a truck, but hands down I like the 268 best. I too installed it straight up.
84 D150 440/727 79 /6 swb D150 1964 A100 window van. Just because it has spark plug tubes doesn't mean it's a Hemi.
If ya haven't been there, ya just wouldn't understand.

Is the low vacuum your only dislike of your current cam? I ask because for about $260 you could install an electric pump to produce all the brake vacuum you need and its always there.

For the price of an off the shelf cam you cna get a custom grind from Comp. Call them and have them spec a cam for your exact build.

XE268 sounds mean in my 451 ,worked good in a 383 too, hits the rev limiter very quickly , set at 6200 ,pulls overdrive like a super star . Would like to try a Mopar 528 solid tho.
