I need a Stroker Cam for my LS2 418cid.
I'm looking for a cam for my LS2 418cid. right now i have a
Comp 250/266-.630/.630-112 but it just don't have what I'm looking for it peek at 6700 rpms I want to crank a little higher and more power.Im looking for a less split ,like in a 248/254 range .I was looking at Thunder Racing sTRoker cam 248/254-.615/.623-110 its good to 7400 rpms but they are back ordered on them. I don't what the lift to be much higher than that because i run 1.75 Comp Pro Mag rocker arms these rocker brought my lift up to .650 on the cam i have right now. you can see in my sig what my engine is built with .Do any body on here have any suggestions.And plus i run nitrous.

You want peak power at 6700? How high are you going to run it?
How much rpm do you loose when you shift.
What power range are you looking for 6000-7400?
The Thunder cam that runs to 7400, is it solid lifter?

Im going to shift at 7400rpm. And it hydraulic cam. I went a head and ordered it,TR told me i should have it around the 6th of August. Here the cam that i ordered>> 248/254-.615/.623-110 and with my 1.75 Comp Rockers it raises the lift to .633/.641 thats were i want to be.

i would of thought that cam you have in there right now would pull as many rpms as the one you are ordering.going by the lift it looks like it's lobes is similar to xer lobes. my cam is 244/248 on a 110 on xer lobes and with 408 cubes it peaks @ 6000-6100 so that cam imo would probably peak around 6300-6400 i would think.
have you talked to patrick about cam selection ?

This is the specs on the Crane Cam that's in my car right now ,I been told by a few people that the split on the duration is a little high, And the motor seems to start holding back after 7000 rpms and the minimum rpms are 3700 rpm ,hard to drive in 6th gear at 55mph at 1800rpms,and the cam peeks at 6800 rpm so it looks like to me there is a short burst of power range in the cam shaft 3100 rpm. And the TR (sTRoker)248/254-.615/.623-110 the cams rpm range is 2400 to 7500 rpms. and the power range in the TR is 5100 rpms.

Yes i under stand,But TR sTRocker cam is specified for a 6.6L and 4:30 gears and that's what i have 6.8L and 4:30 gears .I just believe the cam that TR has is better for my setup than the cam i have right now but i could be wrong but we learn from our mistakes ,Ill see next week.

You cam differently for a carb intake... something like a 257/266 would work great with a 106+2 or thereabouts.
