well after going back and forth on what to do, I decided to go for it. I have wanted to do an LS for years now. My brother has a LM7 that has been sitting for months just calling my name. After going back and forth we decided to try some different combos and just have some fun. A fellow board member came through and gave me a mock up block to design some motor plates and I have been hard at it. This weekend we pulled the BBC and prepped the boat. The boat already has a nice fuel system(carb setup), so we decided to use as much as we already have. The plan was to go EFI single turbo, but the budget started to get a little out of hand. In keeping it simple we decided to go with an E85 blow thru setup and see what it'll do. I have plenty of experience with efi systems and tuning, but have always wanted to see what all the blow thru fuss is about. I am hoping to have the engine in the boat within the next few days, and get all the details sorted before the carb shows up in a couple weeks. I am still missing some parts small parts so if anyone has a line on some stuff(starter/flexplate/alternator) I would appreciate the help. So here we go...

Getting all the dims, its was a pia, had to be creative...

My mill wish I had the resources you guys have, can't wait to see. You can also see the height difference on these plates vs. The ones I gave you. Also I got my motor from A&B truck salvage, they will have plenty of starters and alternators. They had a longblock 5.3 there you could probably take the flexplate off.I'd only deal with the white tweaked dude there, he knows where everything is.

crappy casting....
I went over everything with a belt sander and it'll get powder coated....
-
The valve covers are the same junky aluminum castings, if you want mine without the coil mounts you can have them. I have polished ones I'm using
-
and here we go...
(https://lh4.googleusercontent.com/-7bYJng9IRrU/Tl8YCEF0mzI/AAAAAAAAAPQ/4lEhBiZzA_M/s640/IMAG0254.jpg)
Yes we are using these headers, had them laying around, they will y together at the turbo...
-
I have a whole rack of those coil packs, you can have them if you want. Also that plastic filler neck unthreads and the cap can thread right into the valve cover
-
I'll take whatever parts you have. I was in your hood today. I had to run up to Oceanside, and pick up a turbo. As far as progress the carb is getting done, turbo is picked up, more parts are ordered. I wanted to have the block in by now but the parts I was having waterjetted are taking forever, if they aren't done by Tuesday I will just do them myself. Just gotta keep at it...
-
this was waiting for me when I got home...
(https://lh5.googleusercontent.com/-Tn6JEtcN3PQ/TmaXJls8uAI/AAAAAAAAAPk/2ES4I7dXBik/s640/IMAG0309.jpg)
we continue forward, hopefully the carb will be ready soon...
-
They dont need to clear the transom, they are going to Y together...
-
I think we are gonna need some more pics of this build... I'd really like to see the hull this is going in...
-
I get some pics soon, the boat is tucked away and covered right now...
-
been lagging, spend most of the weekend drinking instead of working. I heard that my carb should be done soon, I am gonna push to get everything in the boat by the time it shows up. more pics to come throughout the week
-
got some more work done

I happened to be designing the side pieces to bolt to the front plate when the power went out last week, lost about 6 hours of work, totally my fault. I have been working on it little by little this week, I have a version 2.0 already done, its much sexier...
-
finally, carb is on its way back to me....
-
ups guy dropped this off, E85 750 Blow-thru...
(https://lh6.googleusercontent.com/-en4QL1piRqQ/To42jtIhF5I/AAAAAAAAAP8/KEpx3fu-Yfk/s640/IMAG0442.jpg)
-
Noob question? Why no flapper on secondaries?
-
the choke horn is milled off for flow/turbulence reasons, and its on the primary side. E85 spilled out when I opened the package, they ran it on the dyno before shipping to me, sure smelled good. It brought back a lot of memories and put some pep in my step...
-
Gotcha. Thanks for the schoolin.
-
Hit a little snag, changed my mind on the turbo size, and mfg. I have some pretty high tech turbo technology on the way soon...
-
this thread requires way more pics
-
this thread requires way more pics
I second that notion
-
I gave you everything I had minus the turbo...
-
lance, have you made any progress on this deal?
-
Updates????
-
the project is once again moving. Sorry for the delay, life has been busy. I ended up starting a telcom company that has been eating my time something fierce. I am just now finally taking a step back and getting to work on my projects. I decided to go twin and ordered two turbos today, along with a large list of other components. Memorial weekend is close and I will have this boat out for that...
-
Twin turbos glad someone has some money
-
The problem is the two wastegates. I am lucky to have a buddy that owns a turbo shop. I went a bit large on the turbos but I always do. Two 66mm units should do nicely...
-
this will be so bad ass
-
Can't wait to see it
-
almost as bad ass as my mini boat
-
almost as bad ass as my mini boat
Lol pretty close
-
I was hoping my turbos would be here today, no go :(. Ordered a bunch more parts today, my debit card is smoking...
-
Still 15 minutes left in the day.....
-
they didn't make it
-
Just got a call from my wife, turbos are in...like a kid @ Christmas
-
u bends for the twin turbo headers are in!
-
Shit Yeah
-
Lance what headers are those? They would make nice upswept headers
-
some headers my brother bought. I am gonna make a single turbo setup from them, and sell it. I'll throw a single 72mm on them with some v-band clamps, and a medium wastegate. For the twins I am building my own headers.
-
<~ this guy don't know dick about turbos
But send me a price, I may be interested
-
call me, I need your # anyway. I sent you a PM...
-
cam, springs, retainers, locks, and pushrods ordered...
-
Hello UPS guy..
-
Nice! Get to work
-
Almost all the parts "should" be here by the weekend. You wanna come down and help me fab? I am planning on getting the headers fabbed up, cam/springs/pushrods installed, turbo oil/return lines ran, etc...
-
Would have to be on Friday or sunday
-
I'll see you Sunday...
-
More parts...
-
How are those bolts for the pto? As cross threaded and effed up as mine were?
-
Look okay to me. Not sure about the other bolts thought, they look a little cheesy. Guess well see how much power they can take...
-
Happy Friday to me...
-
Fed Ex dropped this off today. Turbo 286/234@.050 billet roller, springs, retainers, and pushrods. Oh man, this beeotch is gonna thunder...I am getting excited
-
Got some fabbing done today...
-
Can't wait to see the final on this. Gonna be bad a$$. Put up a vid. Would love to hear it run
-
I am getting pretty excited...so much more work though. Your project looks good too...
-
What's the ETA
-
What's the ETA
good question. I want to be in the water for Memorial weekend, actually the weekend before. Work has been crazy, and I am sure you can relate. The hardest part is getting the parts. Just got a notice from Jegs today some of the stuff is backordered. I am moving along, but it'll be close...
-
Saturday my phone decided to drink too many Mai tais and fell in the pool. Sunday was spent nursing the wife and her day long hangover, getting a guy on Craigslist to change the water sensors in my drunk phone, and then the phone went to the apple drunk tank.

its cool. I am waiting to swap the balancer. Can you send me out some pictures of your current alternator setup?
-
Got my bullets, the exhaust kind...
-
I was hoping for a full day of work, but chores got the best of me. I managed to sneak in an hour of fab. Got two tube welded and one collector done. I bought some formed turbo transitions but decided to just form the 3" collector. A vice, hammer, and a few minutes it all came together. Looking forward to getting more done tomorrow.
-
Progress! If this was a 4 cylinder I be done with the exhaust. Almost done with one side just need a bend for the wastegate. Other side is started, hopfully done by Wednesday. This needs to be in the boat next weekend.
-
time is flying, need to get moving...
-
And then?
-
And then there were two...
-
Engine is looking good, what size we turbos are those? And how much boost are you plan on running? Post the Dyno video when you are finished, love the sound of turbo spool up. :thumbup:
-
67mm turbos, boost will increase until the block tells me no more...
-
got my mounts for the left side of the block to the engine plate done. Tonight I'll drill the plate and tap the adapters. The front engine plate has worked out pretty well. This was one piece that has taken some time and effort. Now I need to figure out how to incorporate the alternator. I went this way to be more universal, and have larger bolts supporting the block. SanDeggo is using 6 10mm bolts thru the water inlets and outlets. I took a different route. He hasn't had any problems, but I wasn't sure about 6 10mm bolts supporting the front of the block. Moving right along...
-
dont jinx it
-
If I remember correctly they're 8mm, the bolts for the head are 10s haha.

I got other scans and diagrams as well.
-
Hahahaha, its not jinxed. You already have one under your belt. Maybe you way is better than mine...
-
If my motor falls through my bilge this weekend I'm gonna be pissed
-
If it does, I know someone who is has a nice rail kit...
-
looking awesome.. starting an LS1 build right now as well
-
I know this is an old thread but just wondering if there are any updates on this project? pics? I'm working on a 6.0L lsx swap into a 16' Tahiti now.
