Default Difference between these Speed Inc grinds for my 402?

What king of HP and TQ agains will I see from each of three cams I am looking into? How will each drive? And will they all be good for nitrous in my 402?

SS1 | 238 244 .605 .612 112
SS2 | 238 244 .605 .612 114
SS3 | 242 250 .611 .619 114

They'd make good power, but you'll prolly have piston to valve clearence issues with all of them. If that is not an issue, it'd be the SS3 for me!.
Sorry, just saw the 402 part. You prolly have valve reliefs. It would deffinatlly be the SS3.

Go with SS3. Drivability won't be an issue in a 400 cubic inch engine. In fact, the SS3 is a very mild cam for an engine of that size, and depending on what else the 402 has, FAST 90 Intake, 1-7/8" Headers and AFR 225s, look for 550rwhp+ easily.

Drivability *IS* still an issue in bigger CI cars... but we can put larger cams in. A 240-250 deg cam is going to have drivabilty issues in a 402. I have some beginings of them with my little 236/236 on a 112. A 402 has 12 more ci than I do, so I would thing upper 230s to 240 should be a nice streetable number. For big power in that range, you may want to look at the LG Juggernaut (G5X4), etc.
Also, a 114 ls is obviously going to drive more kindly than a 112. But will not have *quite* as much midrange.
