    Default new cam/lifters for a stock 460?

    Hope this is the correct section to post this in. I've got a low hour stock Hardin 460 that I'm going take apart to replace gaskets and such (oil pan leaks alot). Would it be a bad idea to swap out the cam/lifters and intake manifold while I have it apart? I'd just like to get some extra power out of it without spending $2k. What would be the biggest cam/lifters that I could put into a stock 460? what else should be replaced? Oh yeah, it's a 20.5' Crusader w/a Berk jet (A impleller I think). Like I said this would be a budget upgrade, is it even worth it? Thanks in advance for your time.

    Don't go the biggest cam you can get. Get the cam best for your'e application. This isn't hooters, biggest isn't always the best.

    I understand.......but I do like hooters.
    Is more info needed to determine what's best for 'my application'?

    If you have a true, bone stock 460 and you absolutely insist on "cam and lifters, period" then I suggest a bang-for-buck Summit Racing SUM-3501 cam and lifter kit. Get a Summit double-roller chain while you're at it ($35) and install the cam-to-crank straight up or at +4*.

    If you have a true Marine 460 then you should have a factory iron intake with the casting number D0OE-9425-C. If so, keep that intake and use the money to purchase a larger carburetor instead, such as Holley 850 Double-Pumper, list # 4781.

    All of the above parts can be had for about $600. If you are willing to spend more and/or wish to build some power then you must port the OEM D3VE cylinder heads and change out the valves, springs, etc. as the OEM 2-piece valves and wimpy valve springs cannot handle much more lift or duration.

    What heads are on the boat now. Between the valve cover and the exhaust flange will be a casting number, 1 letter,1 number,2 more letters then a dash then 1 more letter. Personally I would get a couple more opinions before I would make a choice. also what do want out of the cam and motor. With a cruiser I would imagine torque and alittle more on the top. Do you want to hear it or are you happy with a smooth idle. Are you willing to check the valve springs or just change for the insuarance. I have had 2 different cruisers and ran a certain cam that worked excellent.

    The casting number on the intake is as you say. The heads are D3VE-A2A. I've always liked a lopey idle.......alot!! I wouldn't be against spending the $600 or even a few more dollars if neccesary. Especially if I can gain power without breaking something. Perhaps I should have set a budget to this ahead of time. The previous owner just bought an Edelbrock (only been used one day), which is not where I would have put the $$. I'm a little more familiar with Holley DP.....too late now I guess.

    See if you can find a set of D0VE-C heads. they are getting difficult to find but worth the search. Maybe you can trade that edelbrock carb and cash for them!!! FWIW, the combo I always ran in a heavier boat was the dove heads with adjustable valve train (I altered myself), stealth manifold and a 4780 800cfm holley and a cam just alittle bigger than the 3501 stated above. Small lope to the cam but pulled from 1500 to 5500 and was easy on springs and related valve train parts. Before anybody asks how much bigger I will reinerate ALITTLE bigger than the 3501. P.M. for specs as it is a custom grind done by a friend of mine that has been building cams longer than alot have been alive here.M

    I have a set of dove-c heads worked and a stealth intake on my ford and it spins an A to 5k at 75.

    The current cam i have is a comp cams 343314. Its been a great set up for me. It idles and sounds great.

    That cam that Fo runs from Comp is REAL close to the numbers on the cam I had ground. So for ease of mail-order and a name some people like it's a workable deal and will wake up your'e cruiser a bunch if you can score the rest of the combo.M

    What about these....good deal? Will I still need rockers, lifters and new pushrods? or will the ones from my D3VE heads work?

    Looks like they sell all parts in a kit(including new springs and timing chain)

    If there dove-c heads then that is a hell of a deal. If you jump on that i would suggest having the heads checked prior to using them. Peace of mind. Now being able to use those springs etc is tough to say. If you buy a complete cam kit with springs etc then you will be good.

    Cool....I emailed the guy about them. He has them listed as 'D0VE g'. I'm hoping he still has them and it's just a typo. Thanks for all the help everyone.
