Has anyone had any experience or seen anyone use this motor for a C3 or anything else. http://www.theengineshop.com/product...ron-block.html

I have not heard of anyone using this block before, but for the $ they are asking you can probably find a complete used LS engine with accessories, harness and ECU. Byt the time you built a complete engine with that block you could probably buy a LS crate engine for less $, and have the advantage of an aluminum block.

Iron block is much stronger / durable than OEM aluminum LS block, especially with the splayed billet caps, depends on how much HP you want to make.

its realy a peace oh crap lol 443 is the bigest u can get out of it.

PuddleJumper

im going to add this that your better of going BB or GEN I, III, IV iron block over this. because it looks to be a lot of parts that requre an lot of $$.

its ment 4 peeps who have all the Gen I/II stuff and want ls heads

Its only going to be making 500h-600p.. I dont want much more then that. To be honest, its more about doing something different. Its a fun way to do 427 naturally aspirated, and the design is a bit off the wall. Here is an article on it. Higher than that, traction seems to be not enough.

I haven't heard about a lot of reliability problems with the LS blocks. The main caps on the LS engines are 6-bolt and the LS engines seem to have done pretty well in the C5 and C6 racing programs.

On page 3 of that article, "Quote.... the engine produced an eye-opening 629 hp/579-lb-ft result. That's about 70 hp more than one of World's regular Motown small-block 427 engines and about 15 horses more than their typical Warhawk LS combos."

WOW!!! 630 HP

It's a dollars and sense thing - balance the cost of that block vs. the cost of all the pieces requried to make an LS fit into a C3, sans headers. IMHO, it's at best a wash at this point - a few years back finding mounts and making stuff fit was expen$ive, but it's getting easier and cheaper all the time. IMHO, for $3K it's not a great deal with ready availability of swap kits and prices on LS junk engines (especially iron ones) and aftermarket crates. Scoggin Dickey will sell you a crate shortblock 427 for around 5K!

I wouldn't lose any sleep over the power capabilities of the LS aluminum block. Plenty of C5 guys are getting mondo power out of them...some near 1000 FWHP. There's a guy locally that put down about 700HP at the rear wheels at a dyno day I put together with an engine built by 'tjwong' on the board. Tom can answer your questions in detail about what can be done with the LS...but 500-600 FWHP is pretty much "off the shelf" with an LS these days. Recall that a stock LS6 makes 405+ at the flywheel

Take a look at the main bearing web in an LS - strength is not an issue here.



I understand there are issues with pin oiling if you get up into really big numbers, which is typically addressed by "squirters" that direct oil at the pin as well as a few other tricks. Forced induction to crazed levels can also be an issue with the pressed-in sleeves. But a GOOD shop isn't going to have any problem with this stuff.

My buddy took me to a corner of his shop and showed me a bunch of blowed up aluminum LS blocks when I was thinking about going that route, so I went a different direction and used an iron block.

Told me straight out guys put too much power thru them and they won't handle it. I don't make this stuff up just report it.

When I read Hybrid I was thinking 30+ MPG.

I think for a 'Vette you'd need a battery about 50' square

Should be a nice little LS motor.

But you better have some deep pockets.

The LSx tall-deck will let you get to 500 CID without all the plate stuff.

...but you still need to bring money

I almost bought one of these motors, you need a sb2 style camshaft or ls ,then you need the adapters plates etc. for the top end .throw some ls7 heads 680hp .

What Ive read about the LS engines were the oil pump failures.
and thats when your making 600hp +.
