    Anyone around here running that kind of compression as their daily? Or similar set up as. This? Numbers? Dyno, track, etc.

    78mm BBK throttle body/plenum
    Professional products intake manifold
    TFS HEADS (Not sure which ones yet, car is still in shop)
    Xe278ah comp cams
    BBK ceramic long tube headers
    Grantinelli Motorsport tubeular k member w/ A-arms, adjustable coil overs
    24lb injectors (builder claims to have a set lying around that he'll "give" to me and install)
    Koni front struts
    All forged internals
    Stock crank
    No cats
    Flow 40s
    3.73 gears

    Anyone with a similar build care to share numbers? Perhaps a video

    Turned the keys over Dec. 3rd last year and as long and money continues to come in like planned, it'll be a Christmas present myself! [​IMG]

    I am running a "similar" setup. It hasnt been tuned yet. Mine is at 12:1 with comp 278's. All I have is an idle video. Ill be getting my tune very very soon though. I think you should opt for a little more compression with those cams. Plenty of guys run 10:1-10.5:1 with stock cams every day. Thats about what a pi head swap will get you.

    That is right around what a PI swapped car is at so plenty have done that on DD stangs around here without issue. When I did mine back in the day I just used higher octane gas to make sure there wasn't any detonation.

    Using 87octane with that compression is just fine. Adding the cams means even less octane can be used.

    I did for years with my old setup. No big deal.
