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.

 

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 +.
