    Don’t skimp on quality parts. The labor is what is expensive and you doing it yourself so spend the money on quality chit. Hale marine will have the seals you need for your transmission and inboard online is a great place for damperplates and other indmar parts too.

    I have seen it both ways. For me, I'd add a gasket from the kit (if you decide on a kit) or get one from Discount Inboard Marine.

    Thanks for the reply,
    I actually bought a long block, it was pulled out of a pickup the morning I bought it (guy is doing an LS swap) and this motor was only a couple years old with a few thousand miles on it.
    I am swapping my old camshaft into the new motor because I’ve heard that auto cams are different than marine and can cause motor to pull in water. I have no experience with them so I figure better to be safe than sorry, if it would be better I will buy a new camshaft. Like I said, I want to do it all right.
    Also, since the block was pulled from a truck I figured it would be best to do a full gasket set, will probably keep the heads on the new motor.

    I do have another question, when I pulled the exhaust manifolds off the old motor there was no actual gasket present, it was sealed with a liquid gasket of some sort. Is there a gasket that supposed to go there or is it best to use a liquid gasket?

    Maybe one correction on my last post. If you have an '01 with roller rockers, you might not have to worry about keeping everything in the same order. That may only apply to flat tappet, not sure though.

    -Did you get a short block or a long block? I assume a short block and keeping your heads?

    I ask to know if you need the head gaskets or not? If not, I wouldn't do a marine gasket set. Of course then you'd need gaskets for the risers separately if you are replacing those. You can look on Summit Racing, Jegs, or maybe even Amazon for full SBC 350 gasket sets. I was told by one engine remanufacturer that you'd be fine with even with automotive head gaskets (unless saltwater use), for what that's worth.

    -Did I read it correctly that you are swapping over your current camshaft? Keep all your lifters, pushrods etc. in the exact same order on the new engine, as supposedly the camshaft develops wear patterns with the lifters and other parts. You have to be careful, because it is easy for parts to fall to the ground and get mixed up.

    -The timing is tough on the initial start up. I marked the location of distributor as best I could. It was pretty rough on the first start up. An alternative is to use a timing light to turn the engine over with the fuel pump fuse out. You can somewhat set your timing from there before the first full startup.

    -I used the Altda 106 dampener, I believe. Ski Dim suggested that it is okay, even for powerslot. E basic power suggested one a little more beefy for powerslot and it didn't cost that much more. Don't put the dampener on backwards! Slide it on the tramsmission off to the the side first, so you can confirm the direction. I also had to pick up some lock washers from the hardware store to install it.

    -Make sure you obtain the torque specs - at the very least for the head gaskets and items you don't want to come loose such as the oil pump and flywheel.

    -I'd make sure to get a new timing chain if you have a decent number of hours on the old one.

    I have a separate live thread that might help if you want to look through it.

    started a topic Motor rebuild/updating boat.

    Motor rebuild/updating boat.

    Long story short, I’ve been on this forum for awhile, bought an 01 x10 2 years ago, had issues nearly a month after I bought it (previous threads)
    Well this past year/winter as I was starting to pull things from the motor, trying to figure out my oil problem with plans to have it rebuilt I managed to only drain one side of the engine, cracked the block. Anyway, got a year old crate 350 tbi for way cheaper than a rebuild would’ve cost anyway so I guess it was a blessing in disguise.
    I’ve already pulled the old motor, and pulled all accessories off that will be transferred to the new motor. While I have the engine out I will be doing some updating (will post in the refurbish threads once complete)

    I have a few loaded questions I’ve tried to search for with partial luck and I want to do everything RIGHT with this replacement.

    1) Where’s the best place and best price to find a full marine 350 gasket set?
    2)I will be replacing my manifolds and risers, anyone have experience with the BARR sets? Or should I pay the extra for OEM on skidim? Don’t wanna cut corners but want to make my money go as far as it can.
    3) Aside from the bolt ons (starter, alternator, distributor cap) going to also just swap the entire intake over to the new motor after inspecting since computer, harness is all on there. Will replace all hoses, belts, and pull the cooling system and swap over, and camshaft. Is there anything I am missing? And as far as timing goes, what’s the best way to get new engine timed once installed?
    4) best transmission dampener to replace the old one? Where’s the best place for trans seals as well?

    Please let me know if you have tips, suggestions, or any concerns! Love to hear from guys with experience doing this kind of thing. I’m very mechanically inclined have access to most things needed and prefer to do everything I can myself but I’m also learning as I go.
