I have the 60304 in a 440. Its not a real lopey cam--the duration is about 268/274. Its designed to provide good lift (.493/.513) while still having a good idle.
You are describing the 60303 which has 493/513 lift, the 60304 is 513/533 lift. I run the 60303 and the idle is tame in it when piped through my full 2.5" dual exhaust system. Open the header cutouts and it sounds nice and aggressive.
In all honesty the 60304 is a mild enough cam that adjustable valvetrain is a waste. If you're already got the cam and adjustable rockers, run it. If you haven't bought the cam yet, I would go with a solid instead.

The 60404 should have some lope 234/242 duration @ .050 (and that is the number that counts) Pacs 226/234 is too mild for much lope thats why his MP .474 which is 238/238 @ .050 gave him more lope. that Hydraulic is fine what Torque converter you going to use?? a 3000 and a 60405 242/252 installed at 104 (even 102) would kick but and have a nice lope both 04 and 05 will require re curving the dizzy! IMHO

Never messed with a solid cam. Will it help the performance of the engine. More maintainance?? What are the advantages and disadvantages of the solid over the hyd.?? I do not have the cam/lifters yet. Rockers are in the hands of RAS as I type this!

that Hydraulic is fine what Torque converter you going to use?? a 3000 and a 60405 242/252 installed at 104 (even 102) would kick but and have a nice lope both 04 and 05 will require re curving the dizzy! IMHO
I was going to call PTC when I get the cam sorted out and see what they recommended.

Moparrulzzz, your combo is nearly identical to the one I am building now. Same heads, cam and valve gear with the pistons set at 0 deck height for quench.
Something to look out for. I set my valve lash this past weekend and noticed all 8 of my pushrods slightly rubbed the upper part of the intake runners when the lifter was on the base circle (3/8" pushrod). After marking the heads I pulled them off and hit them with a Dremel.
Also, 440source recommends the locks get upgraded to 10 degree locks when you get above .510 lift, which I did. The machinists was very impressed with the Stealth heads.
Good luck

Thnx for the heads up. Are you running the Holley Street Dominator as well??
