    dont know if your going to see any performance gain. im running a similar cam and im running a single carb with a weiand stealth intake. As for the t-ram, weiand or an offy would be your best bet. Good luck on your search

    The Weiand T/R has runners that are passnger car port sized (like the D3VE heads); the Offenhauser T/R has Super Cobra Jet sized runners. Even without knowing more about your boat, pump, and engine combo, it's pretty safe to say (based on the info provided thus far) that the Weiand might be the better choice in your case.

    Have you intalled that 292H camshaft yet? And are you sure your engine has flat top pistons?

    Yes I put the cam in this summer when we rebuilt the bottom end.Yes I am positive it has flat tops in it.The motor runs good and don't have any complaints other than the 750 carb being too small.I am in the process of purchasing o/t headers for it.It has a Berk 12jg pump with I think an A imp.As far as I know theres nothing fancy done to it.Right now the boat skoots across the water at 62 by gps at 5200.

    When you get this change done, I would be very interested in the performance results.... IMO, and I get plenty of arguments about my opinion, the 750 should be about right in that general RPM range. I'm willing to bet a beer or two it goes slower with a T/ram, even a single quad version, with the same 750, or an 800, 850, 950, 1050..... AND, you're voluntarily asking for a tuning nightmare..... 62 @ 5200 is nothing to be ashamed of with a relatively stock power plant... Remember, boats are suppose to be fun, so leave well enough alone and have fun... If you really want more power/speed, build a completely separate engine and design it to use the extra fuel/air of the t/ram... Keep your existing engine as it is and stick it under a bench. That way when the "big power" engine has issues, ( I didn't say blows up, just issues), you can reinstall "ol reliable" and save the summer having FUN...

    My advice would be to spend your money on Headwork. $1000.00 = - spent porting your Heads will make a world of difference.

    We've had some 40+ years of Iron Headed 429-460 engines around here, so we've seen a few.

    What kind of boat is it ? 5200 to get 62mph seems to be alot of rpms to me. Eather the existing impeller is damaged or it is not what you believe it is.

    seems reasonable to me .I have almost the exact same set up in a 18" rogers,motor ,intake ,850dp,little less cam (xe 274),o/t headers,berk with brand new "a" & I hit the wall at 5200.Don't know the speed but that sounds about right.

    I would aggree with you if it was set up like yours, but he has logs and a 750. My old Sanger ran 82mph @ 5400rpms with an A impeller.

    I agree , head work will make more of a diffrence , I had a t ram on a basicaly stock 460 and I will never go that route again! It took me 2 times the fuel it does in my 545 single carb deal.
    No matter how good she looks , someone is tired of her shit!

    What intake mani are you running now? Are you looking for just bling with the T/R. You need to do some porting on the heads as said before on another thread and this thread. Your correct, a 750 is too small. Should be running a 850 min or go 950. Ford 460's like a lot of carb, but you have got to get the iron heads breathing better. Port, port, port!!!

    Impatient 1 (tom) built my little BBF, and on one 830 dbl. pumper,not a tunnel,runs on average 66/68,and the rmps are about 5500/5700 depending on conditions. Boat is a 18'taylor sj.My opinion,if you want to be a racer,buy a race boat! if you want to be dependable,'KISS'.

    My ford loves the big carb. ported dove-c heads, ported weiand intake, 1050( yes i know its overkill but i have it for my next motor) spins and A to 5100 and 5700 on the bottle. 75 on the motor and 80.2 on the bottle. i saw no gains when i tried a t-ram.

    Ok so for performance,sounds to me the general consensus is no to the t/r.I really am not too concerned with going faster.To me its fast enough.I was just looking at the bling part of it but wanting to stay reliable.It is an '18 sleekcraft sportster.Usually just myself and wife in it.Thanks guys for all of your opinions.Happy Holidays!
