    engine question

    It's true!!! I've seen it first hand, marine engines (stern drives) that ingested water, sat for days or longer with water on top of the pistons (hydro-locked). I've fixed dozens of these by getting the water out and getting them running and up to temp, 2-3 oil changes...BUT THE ONLY ONE I...

    340 stock cam question

    Just gonna throw in my 2 cents... In the 80s I drove my high comp. (10.3) 340 daily. It had a re-ground cam that was approximately 284 dur, 445 lift, 4 speed and 3.23 SG. I balanced the engine where I worked and once you got rolling it wound quickly to 6500 rpm! But...here's the butt, for a...

    Roller cam idea that I'm rolling around in my noggin....

    I was able to talk to an ACTUAL engineer at Tri Star motors. We buy almost all of our Inboard marine engines from them. I told him of a 440/505 I am building and I really wanted to run a vacuum advance and a power brake booster. He made it clearer to me than anyone else could. Here is his...

    Mystery crank?

    Marine engine builders had two options, early days they used an opposite rotation engine in many single, as well as the port (left for you land lubbers) engine in duals, as stated they used a gear drive and different cam. Now the drives are able to change prop rotation so no need for a goofy...

    3.23 or 3.55, this is the question

    Sleeper Satellite...3.55 SG, built 383, yes 55-60mph is really it, but it loves throwing you back in the seat!

    Comp Cam/lifter failure

    This just happened to me! I should have listened to you guys. I checked the bottom of the lifter as mentioned in other posts, flat as a laser, not flattened by the cam, junk quality control. You guys probably will think I am nuts, but I put a set of solid lifters on, yes I still went back to...

    340 Advice

    Bobs right! Holley spreadbore is EXCELLENT!!! MY 340 had one and it really is the best of both worlds, great economy and gobs of power when needed, absolute INSTANT throttle response.

    Roller rockers

    Dude! That battery cable!!!

    OK, Wizzards

    Just my two cents...cam failures are propably most likely because the catylist engines require reduced zinc and phosphorus in the oil, which was very good for cams.

    Which 440 would you build?

    Last year i found a really nice 72 440 block in Ohio, ( I live in Wisconsin too). Standard bore, in excellent shape. Like the others have said, all I wanted was the block, I paid $350. I consider the book "How to build max performance Mopar big blocks" by Andy Finkbeiner to be my BIBLE! It is a...

    340 Advice

    Now I gotta jump in. I owned a 340 with 284 duration cam 445 lift and ran a 650 Holley spread bore double pumper mechanical secondary and that carburetor was unbelievably efficient and had absolutely instant off the line throttle response and top-end. It had a 10cc secondary accelerator pump...

    What Carb do I need

    From my limited experience, l like the ease of edelbrock for they seem to be bolt on ready for stock and mild builds, holley appears to have the almost unlimited ability to "dial it in" especially on performance builds.
