Cam shaft for ls7 headed 441
i am building a 441 with ls7 heads. this motor will see a little bit of nitrous 150 -200 most. i do not drive this car daily, and i can handle a large camshaft as a cruiser (i had a 252-262 in a 408 before this). the motor is being built with 12.1 compression, i was thinking of something in high 240/low 250 intake side, and i would imagine 260+ on the exhaust side around a 110 lsa, i am just having problems finding the proper lift i want because of the 1.8 ls7 rocker. of course i am keeping this hydraulic, and combine with the ti valves i am running should rev to 7k easy. any help would be appreciated.

Ryne just put the special spark plugs in there...they can do everything you don't even need a cam....they will even wipe your ***. lol..you know what i say go big or go home....or go bigger.

note: both cams shown with 1.7 rocker lift, 1.8s will make .624 lift.

Both recommendations are excellent. I like the second cam choice a little better since this is a 441. If I were to change anything, I might narrow the LSA to 112 knowing the larger displacement will make the LS7 heads a little more undervalved.
