LS got pretty refined over time...not sure what that is though. Not a good idea to forego the strut bar, I'm thinking. And hopefully that carpet draped over the dash is to protect the 'fully restored' dash, although you'd think you'd want to show that off in a for sale thread..

I agree, newer LS's are pretty nice, not sure what's in there. I find the chebby engines look so out of place in the 928 engine bay. I like how he says "show car". I wouldn't open the hood at a car show with that in there lol!

I used to work in GM Powertrain and I can't even identify which small block that is. I'm guessing power is right around 220-250ish.
I'd love to have an LS in my car, but I'd take the stock 928 engine over that all day long.

Here is a GM lump I wouldn't mind having under my hood:
http://www.chevrolet.com/performance...gines/ls3.html
No timing belt, no water pump worries, plenty of torques and horsepower, compact and bulletproof.
How much does it cost to build a 32V stroker?
I wouldn't pull a good 32V engine out to do this, but there are great LS choices out there. However, if there are really clean renegade conversions out there, I haven't seen one yet. Maybe that explains a lot attitude-wise.

I've seen more than a couple LS motors with chain failures, engines were junk after that. Common? No, but it can happen.
Unless they are air-cooled this isn't true. All pumps fail.
No such thing as a bulletproof engine. You should see the pile of junked small-blocks piled up behind the Corvette ship my friend owns. Not to mention issues with certain LS engines that make them unfavorable when building a track car.
When my friend builds an LS based track car, if the owner doesn't opt for one with a dry sump they install an accusump and large oil coolers (just like 928's).
Good LS engines start at around $20,000 (see K-Tech for an example)
Friend of mine has upwards of $50k in his LS motor and it's rebuilt every two race seasons.
If you are just looking for "cheap" bragging HP to do the occasional pull on the street.....sure you can get away with a cheap Summit catalog LS build.
If you want something that will actually last (like a Greg Brown stroker) it's going to cost a lot.
I've known far too many Corvette owners "go cheap" on their LS builds for track day cars. They all paid for it in the end.
The "problem" with building a N/A 928 engine is we don't have a "Jegs" equivalent for go fast parts, and IMO that is a good thing.

LS376/525hp GM Performance crate motor runs strong and no problems so far. Bonus: lost approx. 150 lbs weight off the front of the 79 and engine sits lower. New: Approx $ 9,500 delivered to my door including serpentine system re: A/C, alternator, starter, etc. and came with a 2 year warranty. Search around the web cause there even less $ these days. T

Never heard of an LS engine having the valves touch the pistons because a water pump failed.
That being said, I am not looking for an argument. If I had a rogerbox and had thrust bearing failure, I doubt I would put an LS in. Just pointing out that there are good LS engines that offer contemporary hp and torque when compared to a great engine from the 1980's.
