Thread: Blown 351C approximate HP?

    Blown 351C approximate HP?

    Maybe you Ford guys out there may have an idea of approximate HP I may have with this engine setup. It's a 351CJ .010, (I think base 290hp), has venolia blower pistons, SVO high port A3 C302 aluminum cylinder heads, .629 lift comp cam, [email protected] .050 duration, V-671 blower with 2 carter 750's. I can't find much info on the A-3's to see what they may add..once asked an SVO guy and he just said "a lot". It's going into a glass 34 Ford roadster which won't weigh much. Was just curious if anyone had an idea on this. thanks

    I say somehwere in the neighborhood of 850 to 950 HP depending on amount of boost and fuel used. Maybe more just a uneducated rough guess.
    It should be a wild ride anyway in a light roadster like you have.
    Post some pics of the beast so we can appreciate it.
    Goodluck and hang-on!

    It runs fine on pump gas,,actually the engine is rather docile feeling. It's 10% underdriven. Originally in a steel 3w coupe and was quite fast..never had the pedal to the floor..didn't need to. It's an outlaw roadster I'm using it in now..hope to have it together this year.

    If its a street rod, you wont have a very big radiator and if you live in the south you wont be able to run more than about 450hp threw a downflow 15x20 radiator in the summer. i drive mine in the winter and fall when air temp is down, with the boost turned up on pump gas, the motor makes 700hp easy with 12 or more pounds of boost. During the summer its underdriven and I might get 4-5 lbs out of the 6-71, maybe about 400hp

    Your motor should make around 650-700hp also with about 10 or so lbs of boost

    Suicidebomb..you caught that one. Yes I have the 3W yet waiting for me to work on it. I have a chromed out 302 EFI with GT-40 trimmings along with an AOD for it setting on a stage III TCI chassis. It will be a restorod (or mod) My goal now it to finally finish this roadster first. I'll either sell this or trade it along with a glass 41 willys towards a nicer steel willys gasser..but not too nice to street drive.
