I love it.  I spent a bunch of time driving one of those around.

Picked up a 6.0L LS and a 4L60E complete with ECU and harness for $1000 CDN ($765 US at today's exchange). Ran when crashed into. Delightful price.  Pick up one of these and then check out Sloppy Mechanics and tell me you don't get inspired.

We're putting a supercharged 6.0 LS truck engine into a Beaumont at work right now.

When I was researching what the stock bottom end of these engines could handle, I came across a Super Chevy article where they managed to get around 1500hp out of it before it spat out a connecting rod. I think they were using an eBay twin turbo kit and spray.

That's with those tiny stock pistons with almost no skirt on them too.

Do you have the link to that article?  Sounds like a saucy read.

Sorry. My mistake. The smaller engines used CXRacing turbos, this used Borg Warner turbos.

No spray, just 1400hp at 28psi!

Oh you lucky bastard. I've been keeping an eye on those and prices are stupid! That's a steal.

Looks like the harness is uncut too?

Did your success with the TBI tuning tip you towards the LS?

The LS was a significant plan for the '61.

I -have- a Vortec 350 I got for free because it made a ticking noise and the dude thought it was a 305.  But once I got it apart, I found it spun two rod bearings. I get a crank and a couple rods and fix it..... but at that point why not build a stroker? But that that point, why not just move up from 1955 and go LS. The Vortec is still on a stand at work.

I also have a late 700R4 (4L60 non-E) on a shelf that ran when I pulled it, but to make it handle decent power, you're going to spend some serious coin. I want to run boost. So it's still on a shelf. Truthfully, I wanted a stick, but if I boost the 6.0, I may not have a stick for long.  Even the TKO600 -may- not last as long as I want behind a 600+hp LS.

TBI tuning on the V8 Firefly was just because it's what I had, and I didn't want to spend lot sof money on a car I'm going to sell next year. It was good to dabble a bit in OEM ECUs, though things have increased in complexity significantly since 1988. I am reasonably confident I can work my way through this ECU when the time comes.  Failing that, I still have an MSII-PCBv3.0 on a shelf, but then I'd have to find some way to control the trans. With this (and yes, the harness is un-cut, though some connectors got broken), I'm solid.
