    Cam Swap Advice

    Hey guys. Currently im running a 224/224 cam with comp .600 behives, and stock pushrods with a circle d trailblazer I6 convertor. im looking for something much more radical and i wanna get as much power possible. the trucks mods are as follows
    -Rebuilt 02 LQ9
    -Arp Rod Bolts
    -Arp Head Bolts
    -Arp Cam Bolts
    -Clevite Coated Bearings
    -SLP High Volume Oil Pump
    -Ported 317 Heads
    -Pacesetter Ceramic Longtubes
    -Ls6 intake
    -Cold Air Intake
    -E Fans
    -Magnaflow Duals
    -Built 4l60e
    -4.10's
    -AC Delete
    -Dropped 2in all the way around
    -Sitten on 20's

    i wanna go with like a 3500- 3700 stall Convertor, i want a really nasty Idle. Id like it to rev to like 6800 just to keep things safe. as for lift around .600 is good idk how high i can go with the 317's and flat top pistons though. let me know what you guys think of the setup. the cam needs to be Nitrous Friendly. a 200 shot is in its future also what kind of power do you think she makes now, and will make with a bigger cam off the bottle

    First thing I'd do is get some hardened pushrods.

    Unless the heads are milled.

    nope. just ported with a valve job. are the 317's decent heads when they are ported on an lq9? or should i buy 243's and port them

    317's flow as good as 243's they just have a larger combustion chamber, going to 243's would give you a nice bump in compression
