    thanks
    I ran a victor 460, but it depends on what heads your running, the rpm range ect. We need more info to give you an accurate answer. Tell us more about your motor.

    FWIW, there was a shitload of welding/grinding to port match my weiand. Two ports were close to a quarter inch outta place.

    Cool

    The OEM 460 has a lot of potential in the longblock, but it is heavily detuned in stock trim: low compression, no spark advance, low flowing exh in the OEM heads (while they are in as-cast form). Fix those things and it transforms the engine dramatically. And so just bolting on an aluminum high rise intake is not a "magic fix" for the detuned state of the factory engine, but it can offer some improvement.

    The thing about the Victor 460 is that its runners will not properly align the intake runners of the OEM passenger car heads. This characteristic is not in-and-of itself a big red flag but technicallly speaking it does affect overall power potential, and does so more significantly in the rpm ranges that our jet boat engines operate.

    A Holley 850 cfm Double-Pumper atop a Victor can help significantly and it also gives you room to grow, but the initial out-of-pocket is high and the Victor port match to the heads costs as well. If you are on a budget then you can go with a Weiand Stealth # 8012 (not # 8021) and Holley 850 DP which is less cash up front and the ports already align with the passenger car heads...and you still will get significant performance inprovement. But again, in order to draw a lot from the induction upgrade, you really need to address the low compression/no spark advance/low flowing exhaust issues.

    One way to do that is a ported D0VE head swap which will raise compression from 7.7:1 up to about 9.1:1. The compression will be up and the heads are great when ported. Just ad a distrobutor with some advance curve and the engine really wakes up.

    Oh crap the disease has set in and it got both of them. This sounds like it's going to be expensive.

    Starters ...heads, cam and a good intake it will wake it up. Roller cam if you can afford it.

    Good luck.

    I just happen to have a 1971 460 that came out of a Lincoln Mark, this one should be good, it was marked on the core support with a tag from Ford that said 425HP from the factory. I think this one is a keeper for me.

    Is a single 850 on a weiand better than twin 450s?

    Don't know about that combination exactly, but I can say that on a 500 hp BBF build switching from a single 850 dp and Weiand Stealth intake to a tunnelram and two 660s netted me nothing. No other changes and the motor was in good tune with either setup. Both manifolds were gasket matched but no porting work done. Same speed (gps) and same rpm. Was running a 100 shot at the time and nothing more (or less) on or off the nitrous.

    It did mess up my mileage though.

    I went from a Torker 460 intake with a 750 DP Holley to a Weiand tunnel ram with dual Holley 600's. I did pick up a little top end and lost some fuel economy but my BLING factor went WAY up which was my primary goal. No regrets here.

    i will say LAKESONLY knows his stuff. I had nothing but issues with the 460 and I listened to him. he did me right on a set of heads and it runs pretty hard for a heavy boat. let him hook you up

    I have a performer rpm,along with a holly 830,and the dove heads were worked on to align. I do know that if your motor is stock,and you want to go fast! one thing leeds tom another,and another,so have deep pockets,was told many times,after a certain point to go fast,it costs $1000 per mile per hour.
