Comp XER281HR, i have a 4000+lb 06 RCSB 4x4 Z-71 that i'm building an iron 383 for, just about complete and now i'm second guessing the cam i got, 232-234 .595-.598 112+2 i want explosive Midrange power with Decent drivability and still gotta have the Rumpity rump idle, its a DD/Hot Rod, I'm going for 450+rwhp closer to 500, This is what i think would work ok but i may be being too concervative? Comp LSR 227-235 .620-.627 113lsa, what do you guys think? LOL i know its a Stupid thread but important to myself,Thanks for any help

What heads are you going to run on this new motor?? What size converter do you plan to run??

no point in a cam that size if the heads cannot flow it. thats a good size cam though. i it will definitely give you some thump. in the end its all about the tuning. i have a bigger cam in smaller cubes that i can send out with my wife to get the groceries.

drivability is a personal opinion, but i would think that that cam would do what your expecting.

Sounds like a nice set of heads. I would probably run the first cam with a 1.8 rocker on the intake.

Thanks, don't get me wrong I want it to be aggressive yet not be a turd accelerating in OD with 3.42's, I have a super good tuner and the right converter so on paper I think ill be ok, thanks for your input, I do see a lot of guys running 230-240 cams in Even smaller motors so im probably splitting hairs idk

Thanks, I have a lot of time in them, im running T&D shaft rockers 1.7/1.7 and though it may make more power I wanted to keep the spring reliability up, you sir have a BA Truck !!

sounds like a really good set of heads. me personally i would run something with some more lift, maybe a few degrees more duration. the 4in stroke will give you plenty of torque. but that first cam choice will be fine. tuning has a lot to do with driveability.

Id say its the right cam, i ran one similer to that in a 5.3 i didnt think the mid range was to bad, And with 11.5 cr on pump gas i wouldnt go any smaller, i think it will still pull hard in the mid range.
