    Need a cam recommendation for a Ford 302 HO

    While I suspect the mechanics may have to pull my motor next week (sad story) I'm considering a cam change. I've got questions into Isky, Crane, Edelbrock, Comp, and have gone over Jegs and Summits sites.

    Do you boys have any real life recommendations?

    FYI: it's a 1992 Ford HO, 500 cfm 2- barrel carb and stock manifold (for now), 4,800 WOT using a tuned SST 14.25x21" prop.

    I'd be interested in the results of your queries.... please share them here when they roll in

    Any thoughts of stroking that SBF to a 347?

    This is when having a sbc would open up so many choices over a sbf . I've only researching "marine" cams for torque at low RPM and performance from 800-4800 RPM.

    Still waiting for Crane and Comp Cams to reply but their catalogs don't show anything that fits my needs.

    91-95 HO:
    Lift: .278 intake, .278 exhaust
    Rocker Ratio: 1.6
    Duration: 276 intake, 266 exhaust
    Overlap: 39 degrees, 19.51 factor
    Lobe Center: 116 intake, 115 exhaust
    Ford P/N: F1ZE-AA (91-94)

    Don't know if marinized uses a different cam however.

    ​Anyone know if this vintage and type motor (HO) has roller or flat tappet lifters? I cant find it online and my motor won't be opened up for a few more days.

    First year for the Ford roller cam, 1984. It was a 302 HO. Following year most all were rollers.

    Cam advice from co. you stated will give poor guidance. A custom cam for your setup from Bullet Cam will be price matched or below. Old timers at Bullet know their cams and the power to be delivered from any specific engine. Web site ww.bulletcams.com
    Call them, you'll get good advice.

    Well, Crane hasn't bothered to reply and I haven't posted Comp Cams reply yet. However, I guessed flat tappet so the replies are NG anyway. Hopefully my motor won't have to be pulled so the cam issue may be moot.

    No intent to stroke the motor. I'm only thinking of changing the cam if the motor has to be pulled. Otherwise maybe an intake and 4 barrel.

    Pretty sure that's a roller motor if it is a 1992.

    Was this a boat motor to begin with or from a car?

    Just a bit surprised it was still carbed. I have a marine HO not sure of year from an OMC thats SEFI.

    Next is do you know what heads are on the engine? Hoping their GT40 heads. Can be identified by having 3 bars perpendicular to the head mating surface on each end

    My little Donzi isn't nearby and won't for a week or so. I'll check the heads then. The parts diagram only shows carburetors for this year and model motor.

    John, I have the the same motor as you. The factory heads are not GT40 or GT40P. i don't remember the casting but basically they are junk. I put in a 10350701k Lunati cam and Edelbrock performer alum heads this winter. I just put it in the water yesterday for the first time but the motor feels really strong. The cam seems really good for marine use.
