    Low rise TP DP will be the only thing that makes a difference otherwise leave it. Doesn't need air gap of either type until 355 unless its a ballistic 308 but it would be single plane then anyway.

    I'll stick with what I've got but give it some love. The plenum and runner entries are awful. Easily fixed though.

    Hi i use a chinawinder on my 355 in my work ute with some plenum work, it has a 221@050 camtech hyd f/t, ported std valve VNs, std rockers, 770vac carb, 1 5/8 try/y's, single 3inch exhaust, trimatic, 2500 stall, 3.08 salisbury.265/50/15 maxis marauders, runs consistant 358hp@wheels, has ran 12.65@108.2mph (1.90,60ft lol) on street tires zero launch off the line due to major traction issues. those manifolds work quite well with some plenum work, as for low down power, stab it and it spins instantly. makes power to 6200 and pulls to 6600rpm.

    Sounds like a good mild combo that works well for a daily driver including a work Ute.

    Yeh that is good, thanks. 350fwhp should be easy then in virtually the same combo but 308ci.

    Na it's a way off yet, was thinking a bit bigger maybe the ol 286. Got all the bits to go along with it. Another more serious car to finish first.

    Impressive performance for a 3.08 axle.

    What would you suggest? Just a cruiser with a good sound to it. Was thinking around 230@050. Cam is the last thing left to get. Stock stroke, 10:1, fixed up chinawinder, 650dp, cleaned up VN's, 1 5/8" pipes.

    i would go with something like 230in/234ex@050, 280in/285ex adv, ground on 108 lobe sep, 105int c/l and try and get .520lift minimum

    Mine is 308ci (+.040") and similarish to Paul's, with throttle body efi it made 282rwhp on the dyno and ran 13.3 @ 100 in my heavy HQ (1687KG on the scales at Sydney Dragway), when I went back to carb it picked up 3 and half MPH.

    Mine is
    308 +.040"
    Flat top pistons (.016" down the bore)
    Home ported VN's with stock valves
    SFT 244/248 @ .050 .569/.579 lift 106LC
    Defillipo 4 int0 1's
    Edelbrock Air Gap D/P intake
    750 Holley DP
    MSD ready to run

    T400 with 3000 stall

    It's a bit of a bastard combo that could easily be improved on, 350fwhp would be a walk in the park.

    Great thanks. My neighbour runs Franklin Cams over here. He will make that for me.
