LS Build: In Progress

I would love to know myself. Lol. We did a full repaint, interior, powdercoating, etc. We are giving the paint ample time to cure and release all solvents before we crank down the fittings, drives, etc and cause a blistering issue. Currently top is just about cured and sides are maybe another month behind.

Still playing the hurry up and wait game. Didnt miss a whole hell of alot. The lake in phoenix were closed half the summer. So it chaos now that they are open. Havasu has had a limited amount of people allowed so mile long lines to launch. And now the colorado river is like 3 ft deep between havasu and laughlin for an “experiment”. Season here is tossed. Still not ready to mount hardware/drives/etc as I am more worried about a full cure on new paint. Can still leave a fingernail mark in paint. So like I said. Hurry up and wait for the solvents to work their way out.

Good morning, I am embarking on a similar LS engine swap and wonder if I can pick your brain. A little about my project, I have a 1990 Baja 265 with no engine or outdrives, I have found a Bravo 1 outdrive for it and in the process of having that picked up and shipped. I work with a guy that has a 2003 Vortec 6000 truck engine he wants to sell for $1000 and it is nearly complete (no computer or harness but otherwise should be complete). I have a short list of things I need to complete the swap and I will list them here, I would love if you can look at what I am doing and give me any recommendations.
My biggest differences with what you have done is I am planning to use the factory intake and computer/harness.
Thanks in advance
Kevin

I just bought a set with the brackets and the adapters. I just ordered a set of the LSA blowers also.

Do yourself a favor and pull the intercoolers and gusset them. Also run the zl1 lid if possible. Good for 20 or so hp and intercooler is more efficient. Port them as well. I did mine. Pay close attention to the area right above the gasket area that mates to head. Youll notice square edges. Round those out and open them up. Injectors I would decap the zl1 injectors and have them cleaned and flow matched. Good for 105lb/hr. And cheap. Last but not least a nice little trick if you dyno them and your ecu has capability is to fire injectors the second the intake valve opens or 0-5 degrees before and stop them at or before the valve closes. Easy BIG hp gain and does let fuel pool behind calve/cleaner afr etc. I actually showed my dyno guy this and he couldnt believe the gains. Over 40hp in my case. If you have overlap and can get enough fuel in within the valve event I suggest injecting after the overlap event. But only if you can get adequate fuel in by the time it closes.

I just read through this entire thread, tons of good info and I look forward to seeing more progress. Really hoping to dive into an LS swap in my boat soon and will use a bunch of information from this thread.

Glad I could give you some inspiration. Currently the boat has been sanded back down as getting ready for second paint job. We had solvent entrapment in the basecoat aka it never fully cured and would have come off in sheets. I am however getting very good at sanding as I have hundreds of hours doing it. Paint will be on boat within the month. Just waiting for weather to get a little warmer to ensure epoxy primer has at least 24 hours over 65f. Everything else is done. New interior, powdercoated all billet parts, painted and refreshed drives and gimbals, etc. Two steps forward on step back. Will be shooting it in single stage this go around PPG Delfleet (much like old imron) in 2 colors.
