Sounds great!!!

My new engine has cathederal port heads but is not LS. Cannot wait to see how it pulls. I will be moving 12K GCVW often.

Who said it was going to be a street car???? Its getting a TH400 with a ~4,000 stall and 4.56 geared 12-bolt with a big Holley on top in a ~3,000 lbs car.

Honestly in open loop or PE not much at all happens from the o2 placement. My tune is just fine and my part-throttle air/fuel ratios are right where they should be. I have been tuning long enough I...

You are mistaking on the LT1 vs LS thing atleast LT1 Vette vs LS1 Vette. The LT1s put down a better 60' because they make peak torque at a lower RPM.

Actually I am and doing it with a stock 12cc dished piston shortblock and ~9.5:1 compression ratio. The old Gen1 engines INCLUDING LT1 make more low-end and midrange grunt than stock LS engines.

If they flow "plenty" of air then why do these engines gain 20-30 HP from long tubes???

Actually not about that at all! Just said I will keep my old engines in my trucks and build fast cars with the new ones and YOU challenged me to it. I am actually building 2 of your favorite 6L...

I guess these old 350s are just garbage and don't work in their intended environment or work efficiently LMAO!!

My brother and I drove from Fort Worth to San Antonio, TX today to pickup a Jeep...

Its still going to cost you a grand to swap that into a car and get it running. Not to mention to put down that kind of power and hold it you are going to need most of my parts list anyway. Cooling...

That one was not mine, check out Something New Something Old by GM High Tech. I had a very similarly built 383 TPI in my 1983 G20 that put down 430 RWTQ.

I put down 370 RWHP on a Mustang dyno through a 4L80E and GM 9.5" 14-bolt. I put down 340 RWTQ at only 3,000 rpm with a locked converter and peaked about 370 RWTQ at 4,500 rpm. At only 2,400 rpm it...

Exactly, I had two different Titans because I work for a Nissan dealership. I was amazed at the power I was able to get out of the stock engine with only intake/exhaust/tuning. There are MANY good...

And please don't get me wrong guys, I LOVE the LS and the modern "HEMI" engines in CARS. But I will keep the traditional, larger cubic inch "GRUNT" engines in my trucks.

My 350 outguns this 6.0L everywhere under 5,000 rpm and if you count the fact it is just a stock vortec 5.7 shortblock with a cam, a good pair of aluminum heads, a relatively cheap marine intake, and...

The crossover point is higher up around 4,500 rpm. The reason for the elevated peak is port size and velocity. The LS head ports are HUGE compared to the older stuff. I have older Car Craft...

That is the Marine NET rating, with a 4bbl car, headers and minimal accessories it put down 338 hp @ 4,400 and 444 tq @ 3,400. With roller rockers, an intake and carb change it put down 379 hp @...

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...

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.
...

Definately reinforces why my cheap LQ9 build will end up in a car and when the 5.7 Vortec in my Express dies, will have a 383 in its place. Nice top-end HP, NO guts down low. Also CHEAP can't be...
