    Yeah, I'm feeling like my 6 year old son at Toys R Us! I've got a lot of business travel coming up and I'd like to see if I can get a layover close enough to allow me to go look at it. And I still need to fix the 18C and build a garage!

    Stock 350 for the 18

    Hi Chip,
    Not been to this sight for a while; life's been crazy. Bummer about your engine!
    If you plan to buy a 22' in the near future I'd just buy a stock long block 350 to swap out in your 18'. They can be had for $1500...
    As for the 22' Shelby, that boat is beautiful!
    Thank you, Patrick

    I'm going to look at a 22 tomorrow with a 496HO. If it's a solid boat I'll probably buy it and put the 350 long block in my 18 and put it up for sale. If the 22 doesn't work out than I think we are building a 377 long block. I like the Shelby but I'm not sure I want to spend that much right now. It's a great looking boat on the trailer but it's a long haul to drive to IL and back. Stay tuned. I have to make a decision pretty soon on what I'm going to do.

    The Shelby is a real looker but not sure they are worth the extra $$ over a stock 22.

    Good road trip, nasty boat

    So I went to Jacksonville and looked at the 22. I have to say, and I'm trying to be nice, but that was one of the worst looking 22's I've ever seen. It's just been used hard and not well maintained. I took a friend with me so the trip wasn't a complete waste.

    On the other side of things I've decided to go forward with the 377. That will let me enjoy the 18 until I decide what to do on a 22 and I have to put a motor in it so it may as well be something I'll enjoy. The 18 is a nice boat and when it goes it will make a great boat for someone else. I'll post what the plans are for the motor as we get the list of parts together.

    350HP 383cube

    Looking forward to following your project Chip.

    I've not ever built a stroker.
    I've got a nice 4 bolt 454 that's been sitting around for 10+ years.
    Thought at one point I'd build a 496 but I ended up buying a 502 instead.
    Thank you, Patrick

    GM Performance Parts

    The beginning of the plan is to use all GM Performance parts including 9.5:1 compression pistons and a GM cam kit that includes springs, rollers, etc. Duration is 218-228 with .525 lift using the stock crank and con rods.

    Stock Crank & Rods = 350ish cube engine?

    Hi Chip,
    Are you rebuilding your existing short block and buying new heads or are you buying a stroker long block or other?
    I'm assuming that cam is a roller with that much lift.
    Have you pick heads, intake, or any other parts yet?
    Do you have a plans for exhaust upgrade?
    The last 350 marine engine I built was for my 20' minx. I rebuilt the 270hp mag into a 320hp tempest. That engine had a flat tappet cam.
    Thank you, Patrick

    It's going to be a 377 long block. I'm just not comfortable rebuilding the 350 after salt has been all through it. I'll probably use the stock manifolds but it will have 9.5:1 pistons and yes, the cam is a roller. It will be carbureted and I'll be reusing my exhaust manifolds and risers as the boat was only used about 8 times since I replaced them. I might bite the bullet and buy stainless risers but haven't decided on that yet. I can also reuse my alternator, starter, etc. as those were all replaced when I replaced the manifolds and risers. I'd like to use as much of the stuff that I just replaced as I can. This boat is seriously turning into the phoenix. It just keeps rising from the ashes.

    Stainless risers

    I used these on a 454 with stock manifolds.

    I had installed a larger cam and was worried about reversion. They are pricey, but if your manifolds are new...
    I'm not sure of the overlap of the cam you have selected, but my guess is that you probably shouldn't use the stock risers if the LSA is less than 114deg.

    Thanks Pat. I'll check these out. Either way I'll end up with these or something similar.

    Progress

    So life has gotten in the way of the boat but we're making progress on that. And the garage addition is under construction. Lot's of work related travel this year and more to come, but... the new motor is together. It should be running on the stand in the next few days. Here's a couple of shots, before and after paint.

    Looking Good!

    Roller Rockers and High rise with Brass water passages.

    What Carb and Ignition??

    Did you pick exhaust risers?

    If your travels bring you to the north east, gotta stop by...

    Fun project
    Thank you, Patrick
