GENERATION III - I recommend sticking with the Gen III engines due to the large production#s and the resulting cost effectiveness.
LS1 - 5.7 (346 CI) - Between 305-350 hp and 335-375 ft·lb
1997-2004 Chevrolet Corvette C5, excluding Z06
1998-2002 Chevrolet Camaro Z28, SS
1998-2002 Pontiac Firebird Formula, Trans Am, Trans Am WS6
2004 Pontiac GTO
*97-98 Had Perimeter Bolt Valve Covers
LS6 - 5.7 (346 CI) - 385(01 Vette only)/405 hp and 385(01 only)/400 ft-lbs.
2001-2004 Chevrolet Corvette C5 Z06
2004-2005 Cadillac CTS V-Series
*Basically the same as an LS1 but with better heads (243 head castings) a more aggressive cam, and LS6 intake manifold make up the power differences.
TRUCK ENGINES - STILL GENERATION III - 285-295 hp and 325-335 ft·lb
The truck engines are very much like the LS1/LS6 and are still classified as a Gen III engine. They are mainly iron with the exception of the LM4/L33, and as a result weigh approximately 80+ lbs. more. All the parts from the LS series can bolt on to these engines and is recommended for any swap as the accessories and intake manifold usually fit better from an F-body. The 4.8 and 5.3 can both be punched out to a 5.7 (346 Cubic Inches) simply with a bigger bore (the 5.3) or a bigger bore and the 5.3 crank (in the 4.8's case).

Quick summary of the major engines and their compression ratios and GM part #s:
LS1...346c.i. 5.7liter 10.19:1 25534322
LS6...346c.i. 5.7liter 10.46:1 12578104/12562190
LR4...293c.i. 4.8liter 9.47:1
LM4...325c.i 5.3liter 9.49:1
LM7...325c.i 5.3liter 9.49:1 12562201
L59...325c.i. 9.49:1
LQ4...364c.i. 6.0liter 9.41:1 12575147/12575148
LQ9...364c.i. 6.0liter 10.08:1 12499467

For those not in the 'know'.. all 5.3, 5.7 & 6.0 engine use the same crank & rods. The 4.8 & 5.3 share the same iron block & pistons.. the crank & rods are different in the 4.8. Also, a 4.8/5.3 block can safely be overbored to 5.7 spec & use the 5.3/5.7/6.0 crank, rods & 5.7 pistons to 'make' an iron block 5.7 from an iron block 4.8/5.3.

we need models like this guys...

Do any of you gents know of an aluminum 4.8 or 5.3 block? I've seen two advertised on the local craigslist but haven't heard back from e-mails to the sellers about what they came out of or casting numbers. First impression is that they're full of it, but thought I would double check as my V8 swap will be aluminum, and the aluminum 5.7 and 6.0 blocks are just too pricey for my budget.

The 5.3 LS4 was an an aluminum block. It came in the FWD cars.

There are also some 4.8 aluminum blocks, I'm not sure what models have them though.

there are aluminum 5.3's that came in the later model trucks. idk about the 4.8

L33 block is the aluminum one.
 
 

Yeah I believe the aluminum blocks started showing up with the most recent truck redesign or a couple years before.  2005 or 2007 I don't know for sure.  They're definitely pricier when I've searched junkyard listings.

Yeah the aluminum blocks are all over the place escelades H3's vette's camaro' Not in 5.3 of course but hell yeah there all over and they are cheap.

not out here they're not, lol. Out here an aluminum shortblock with less than 60K miles(all I've been able to find) is running $1K.

Goto www.car-parts.com
 do a search in the midwest. I did because i live in MN. but i found a bunch under $500 even. I paid $400 for mine it had 75xxx but even if i got one with 10xxx on it i would still do ATLEAST oil pump all bearings and rings to it. If it doesn't have a big ring ridge, you can do a dingle berry hone to give it a nice crosshash. Either way you go at it, when you get one take off the oil pan and start from there. open the oil pump up and take off the main cap furthest away from the oil pump.     But, you can buy a more expensive one and probably just chunk it right in.   good luck.

Hey, by the way if anyone knows of someone doing a 4x4 blazer ls1 swap. have them send me a shout. I need a mod oil pan or something that will work. i think i have even less room because it has the 7.5" front diff. also anyone doing anything to a zr2? I wanna see what other Z's are doing. everywhere else i look its all mud.  Thanks

Been reading up and can't find anyone whose done it, but I thought you folks might be among the most open minded about the idea.

For my total design weight savings are taking priority #1, priority #2 is going to be getting what weight there will be down as low as possible in the chassis. For those reasons I have my mind very firmly set on an aluminum engine, the most prominent of which are V8s. Unfortunately for me, the price of aluminum gen1 SBC blocks or engines has rocketed. I can find none used, and the only new I can find are $4K full race blocks like the motown lite, and that's just not an option. I had originally been planning on an all aluminum high compression 302. Seeing as that's no longer possible, I'm thinking of building a de-stroked LS2. Aluminum LS2 blocks are going pretty cheap around here, and aluminum L92 heads are the most reasonable high performing heads I can find around(brand new GM racing heads are $1K a pair, fully prepped for high lift, used are around $600 for the pair in good running condition) and 4.8L iron short blocks are just about being given away down here.

That has developed the idea for a 327 L92.

I do not intend on winding it over 7K for prolonged periods, but would like the weight savings as I'm really hoping for some open-road/targa racing down the line and would very much enjoy the fuel savings and broad rpm range of a short stroke engine.

P.S. It would be running an MSD controller for the stock coil-on plug system and a carbed intake with a propane carb. 

Nothing good comes easy dragon. Is this for a 2nd gen Blazer? I was just about to bite the bullet and buy a iron block 5.3, then I heard of a de-stroked 400 small block for sale for the right price. I bought that and now i found a really good deal on a 98 5.7 complete engine, harness, ect... All for $700. It's like when you have a girlfriend, and she's great, you like her... and all of the sudden, you start to get hit on by a bunch of hot chicks that just turned 21 and want to get drunk and screw.

lol

My friends knew a guy in college that quit his job at the howard johnson, but before he quit, he programed that sign...


I present to you...the HOJO pics:















there is also a video, which is 100x funnier,  but i can't find it. lol

That's awesome, I wish we had a sign like that. We're situated right next to a major freeway and I work completely alone at night, so that could be VERY fun.

haha
