LQ4 Power

[Fast355]

What do you mean no guts down low? Over 400 lb-ft under 3k..... If the graph would show it, it was over 350 at 1500 rpm. This is only 364 ci under 9.5 to 1. Shorter stroke than a stroker and stock heads.

I was putting those torque numbers to the TIRES through a 700r4 and 8.5" 10-bolt with a TPI 383 with vortec heads and a small cam!!

My VK56 put down 365 RWTQ on a Mustang dyno at just 2250 rpm.

I like the Gen3 and 4 engines but the Gen 1, 1E and Gen2s definately hold their own under 5,000 rpm!! I can pickup a marine 6.2/6.3 aka 377 or 383 and even get them reman and destroy the 6.0 from off-idle through 5,000 rpm.

Whats the cost in that? I'm less than 3k in this entire setup, including engine and dyno time.

So the point of this is for me to provide TRUE and HONEST numbers for MY cams. I'm not here to start a pissing match, which I'm sorry if I did by posting a stock LS setup....

Not trying to get into a pissing match. I think you have a great build with great HP per $$$.

I am just mentioning the old Gen1s still have a place in my eyes in a heavy truck/SUV or Van that is going to tow or haul. I think it is interesting to watch someone pull a solid 350 or even 454 out of their ride and slap in a junkard LS and spend a ton of money on the conversion. I also know good LS deals are out there. I got my ready to assemble LQ9 short block for $550 and bought a good 2002 LM7 5.3 for $100. Its going to cost at a minimum $800-1000 to put a LS engine in place of a 350 or 454 and get it running. You can realistically say your 6.0L installed in say a 1998 K1500 and running would be $4,000.

The Marine 6.3 and HT 383 are the same thing with the 3.8" stroke and the Marine 6.2 is the same engine with a 3.75" stroke. All 3 are using a 4.00" bore, vortec heads and the tiny' 395 marine cam that is 196/206 @.050.

I have built a Gen1 TPI 383 with ported vortec heads for under $3,000 as well.

I saw this testing done on a HT383 and it is a monster.

I became an LS fan after purchasing our 2006 Yukon with a 5.3. Very smooth power delivery and excellent unloaded fuel economy. I was surprised though that when towing the economy isn't any different than my TBI truck, my dads old carbureted 350 truck, or the 454 powered 1-ton '79 GMC we just acquired.

I'm in the process of a complete resto on my '66 Nova. It had a fresh drivetrain, TBI 383 and a 4 speed, before I tore it down for paint and body work. Last year I found a great deal on a complete 5.3 with harness and computer so I bought it thinking this would be a good time for an LS conversion. Then I added up install costs - oil pan, radiator, motor mounts, headers, bell housing, flywheel, clutch, etc., etc., and decided the 383 will be just fine. The nova will see an LS someday, probably with a turbo or two...
