the lift isn't what hurts you, it's the long duration & camshaft centerlines &/or valve overlap, especially if it's mainly 98% street driven & an automatic... I would suggest not going over 280*-290*-ish max "advertised duration" at all, {unless it's a really big cubic inch engine, you have all the needed extra necessary parts etc., ported heads, good rods, balanced steel crank, blah blah blah, you don't or won't need it}, IMHFO the lift won't hurt you really, as long as you have the proper clearances everywhere, the proper style machine work done, you have the proper style adjustable valve train, rockers, pushrods length & style etc. & the heads, carb, fuel system, proper sized fuel pump, lines, pick up/sending unit, intake, proper ignition system & exhaust system to handle the added flow, also the proper gears the TQ converter stall etc.... Just don't be cheap when it comes to your heads, camshaft & valve-train components, I highy suggest that you contact/call a couple of reputable camshaft manufacturers Comp, Lunati, Crane, Isky whom ever or a custom camshaft grinder & be totally 100% honest when talking with them, tell them what you actually want to do with the car, be completely realistic, not some fantasy miss-matched cam-heads-carb-intake combo & how it will honestly actually be used... IMHFO you will be much happier & money much better spent in the long run, spend it correctly the 1st time.... my $0.02cent, I usually won't & don't give anyone camshaft recommendation, it should be left up-to the camshaft experts, to match your intended usage, your specific parts combo & all necessary needed parts... good luck & happy Moparing
