[email protected] first pass
Got the heads off and pistons out. Everything looks as, or better than, expected except that rod bearing and journal #1 have a minor scratch. Just barely catches a fingernail on the journal. Think it'll be alright, but I'll give it a closer look tomorrow. The rings all move freely and aren't gummed up and faces all have the expected amount of carbon build-up. Lot's of build-up in the intake ports, both in the head and manifold... Ordered valve seals.
I've never been in one of these engines before this. It's a real pleasant engine to work with. All the bolts come out nice and easy, the gaskets come off so nice and clean that they're virtually reusable. No scraping, no prying, no busted knuckles. The parts and machining quality over the older factory small block stuff is a very apparent improvement.
Hopefully get the heads apart tomorrow.
Yes. I'm tearing it down in the filthy bed of a pickup truck.
A little bit about the plan for this engine... EFI, twin turbo, big intercooler. I've collected a lot of parts over the past year, but from here on out it's a shoestring budget. A BIG thank you to Impatient1 for all of his input and guidance on parts selection.
70mm Turbos 0.81 AR turbine housing
Cast iron center rise manifolds
Microsquirt EFI ECU - Super compact (wallet size), boiled down bare bones unit. Batch fire fuel and wasted spark ignition using stock coils.
Cam driven fuel pump
Probably an LS9 cam for the time being
Maybe vacuum pump (OEM Smog pump)
Only looking for an 80-90 mph boat and think this should get me there.
I have a lot of book knowledge about engines, but hands on assembly experience pales in comparison. I'm confident I'll do fine, but if you guys have any input along the way, or see a mistake, I'd appreciate the heads up.
Shouldn't take more than 2 weeks.

That is going to be a neat combo..boat/engine. Thanks for posting it up!
I've been running my 01 5.3L hard now for 4 years. Tough little motors. You'll like it

Dare to be different, if it turns out great you can claim you planned it that way.
