I'm not a fan of Edelbrock's meager selection of cam grinds. I'll see if I can find something and reply later today...

I would look into CompCams. They have a ton of options. With the Cleveland heads, you are going to want something that is going to have a high power band because your heads will have air velocity problems at low rpms due to the large runner size.

Take a look at something in their solid flat cams Magnum line for the 302. I would think 31-335-4 or 31-334-4 are going to be pretty streetable, does not have a bunch of lift or duration, but would make power out to 6500 which is were you will need it with those big heads. Velocity is going to be important and hard to come by with this motor, and engine speed is going to help.

it depends on the weight of the pistons. my old 302 with the regular wav-loc bolts were only rated to 5500 even with the rotating assembly balanced with the heavy *** old school pistons i had on there. didnt know that until it blew up and i sent a piston/rod to ARP for bolt analysis. now, the same rods and bolts with lightweight pistons could have spun to 6500 or higher without a problem.

add the stronger of the arp bolts, take into account the better rod / stroke ratio of the 289, balance everything, and you should be able to turn 7k+ without a problem unless the pistons end up being slugs.

you wanna post the links to the two cams we discussed last night and get some input on those grinds? im definately a fan of the newer bump sticks being offered, there is alot more research under their belt compared to when they were grinding cams 20-30 years ago (most flat tappet grinds are old patterns)

That's one mean cam there. I agree, that would work great with your setup. It would be very windy and produce gobs of power above 4k.

Another option to consider is a roller conversion. I'd still recommend solid lifters with the rpm's you'll be turning, but a roller cam will allow you to broaden the power band of the motor. The end result is more peak power without sacrificing low-end driveability (what little you'll have, in any case).

Yeah. I'm not a big fan of some of the older Lunati grinds, but that Voodoo cam matches your engine pretty well. I bet it winds to 6800
