This is my first motor build so I don't know very much. Its a '78 small block 350 with long tube headers, edelbrock 750 cfm carburetor, weiand intake, slight porting in the heads, bored .60 over and the heads haven't been decked. Its going in a mud truck so I want something with a good lobe and bottom end power, I've heard the voodoo 1012702 is pretty good, any comments? Also if ya'll have any suggestions to valve jobs, sizes, or other performance doo dads that wont break the bank it would be appreciated. And one more thing, I was thinking of installing an external oil cooler, yay or nay, thanks Laugh

Lumpy idles and good bottom end power do not come in the same engine combination, you get one or the other but not both.

Cam a good cam recommendation we need to know what transmission, diameter tire, and differential gear you plan on running. It would also help to know if you have stock crank, rods, and pistons or have forged components.

It's on 40" tires, turbo 350 trans and summit racing flat top pistons, stock crank, stock rods, no forged components and 4:10 gears, I guess since you can't have the best of both worlds with cam choices I'm just looking for something with good bottom end and good power followed after

id probably go with a cam of around 262-268 duration.

 the only bad thing i see about an external oil cooler for a mud truck is possibly ripping a line off from a stick or log.    unlikely, but possible.

Hi there,
 I would trade the 750 carb for a 650 DP and use a 216 218* cam
 with about 450/460 lift at valve with 100lbs springs.
 Keep the comp above 8.6 to 1 to match the DP's 68s front and back
 to start with..Good luck...

This is a cam I have used in the past on a 4x is, I've used it on an early Camaro also with very good results-

Melling/Camshaft Part Number: 22301

Price: $84.99


You can get this cam at any AutoZone and it's a lot cheaper, and is similar to a Lunati Bracketmaster II cam.  

or

NORTHERNAUTOPARTS.COM has it cheaper online-
