So why lie about it ???

If ya have to lie to win.......

I had my reasons. Whether I lied or not the outcome wouldn’t have made a difference on whether telling the truth or not. Let’s just say he was lying big time as well.

Yes but a truck with 600+rwhp will not run as good at the track vs a good auto trans with a good converter. No one can outshift a auto IMO

That wasn't my point, and the manual would be used for TRACK tracking, not DRAG tracking. Anyway, my point was, would it be easier to run a torque tube and mid mount a manual for weight distribution than doing the same with an automatic?

Also, 0.4L bigger and I'd have to ask you to make it smaller! Or go with more cylinders

Just my OCD for you. The first step is more than 50CI per cylinder. Then it's more than 1L per cylinder. Going bigger than those for anything other than a semi is too big {in my OCD's opinion} to be going in a 'car'. I mean, it won't rev worth a damn and be any sort of streetable if it did! {{V8's have this magic **** going on where they can rev really high almost regardless of stroke, though, so they usually get the pass to the 1L per cylinder mark rather than the 50CI per cylinder mark. I mean, a 572 chevy still peaks at, what 6500?? That's 9.4L!!}}

Well all I do is drag race so a manual won’t be good for me unless I was going to make her a cruiser. Now other than going big cubes is that I also went with a aluminum block which saves 100lbs off the front end. Since I went Aluminum I decided to go as big as I could. I want a 10 sec pass All motor and if a 4500lb car can do it in Texas summer heat then I don’t see why I can’t. See this set up will rev till 6700 and no need to rev any more if Reving to 6700 gets the job done.

Well, you still didn't really answer my questions, so I guess I'll move on.

With your numbers from your last build, and from other builds you're seeing, what're you thinking this motor'll do? 600 wheel? You gonna throw No2 behind that? How much?

I bought this motor from my friend and kept the same set up. I just replaced the pistons with new ones. He made 602 rwhp NA thru a Nag1 and ran a 10.7@125 NA in +1740 da in Texas summer heat @4460lbs with 3.73 gears with 93/c16 mix. So I’m hoping to make the same but it will be thru a 4l80 with 4.56 and 250lbs lighter and I’ll be on E85. I do plan on spray but not sure how much at this time.

I'm estimating a 10.3-10.4 quarter for you. The gears, weight, temp and alt difference, and the E85 with matching tune and fuel flow will get you there by my wild guess.

I'm under the impression that anything over a 200-250 shot is 'professional drag car only' level. Like these big crazy nitrous motors running 400, 500 and 600 shot of nitrous {supposedly}

So I'd say, if you think the motor can take it, and you don't wanna make this a nitrous only, drag only truck, run a 200-250 shot. With the ~600 to 650-ish HP you're already looking at at the wheels, you just about won't NEED a fricken turbo or SC after the No2.

And, ****, if you're already looking at low 10's, it's not like you'll always HAVE to use the NOS, either, right?

That would be my goal NA in good weather, but I’ll be happy with 10.5-10.6. The good thing is that the ladder bars and double adjustable coilovers will help with weight transfer and traction. My plans when I spray would be like a 100 shot and later move onto a 200 once I get a feel for the Truck and that power. But my ultimate goal was to be the 1st to hit a 10.xx all motor in a Dodge Ram hemi so until I do I’ll hold off on nitrous.

Many tell me I should’ve gone turbo but to me a NA set up that runs just the same as most turbo trucks is far more impressive. I will say that eventually I’ll love to go turbo and see how it feels.

Big displacement {specifically, stroke} supposedly doesn't work well with forced induction.

So how come big drag racing engines are sized 500-600 cc with crazy amounts of boost putting out 2000-3000 hp? Lethal Hemi is building a dedicated drag racing engine, I’m sure he’s been in contact with some top engine builders if he’s getting all this work done. I think he knows what he’s doing and trying to accomplish

I'm not debating that, that's why I said 'supposedly'. I heard boosting big displacement motors, especially with long strokes just isn't as efficient as doing it to a shorter stroke/overall smaller motor. There's like a limit or peak with bore/stroke to have the most efficient process with forced induction.

Kinda like how 2 strokes have the most specific output around 120-135cc per cylinder with a very specific bore-stroke ratio. {{IE, a racing 125 put out in the high 30's/low-mid 40's of HP, while a racing 250 is only in the high 50's/low-mid 60's of HP}}

In no way am I saying a 5.7 with turbos will make MORE power than a 468 with an otherwise matching setup {boost, cam, turbo size, head flow, exhaust, etc} can, just that, from what I've been TOLD, it will be less efficient; the specific output added per PSI will be lower. Supposedly.

IDEFK if it's true, dude, it's just what I heard.

What you have heard is a vast generalization and can be a load of horse **** depending on the build and use. Long stroke builds make a lot of power in the lower RPM band so if your plan is to run a long stroke engine at 6000+rpm then yes, it'll be inefficient because of the inertia cycling of the piston and the very likely occurrence of under filling the chamber with air; it's why you see high rpm engines running smaller pistons and short strokes.

If you take the same long stroke and put boost to it then run from 2500-6000rpm you will have a very efficient torque monster that will win 1/8 and 1/4 mile races but won't be any good in a 1 mile event. Vast generalizations are useless and unproductive because it has a lot of assumptions which may or may not be relevant to the specific end use of the engine. The boosted engine is running a VE>1.0 and pushing a higher air mass flow rate.

I wasn’t going to use this 468 for boost. I have a spare 6.1 block I plan on stroking to a 426 and going turbo. I’m kinda leaning toward whipple at time but I love the should of the whine from a whipple but the turbo sounds so good as well.

Bruh. I've been listening to prochargers for about an hour now. It's the best of both worlds in terms of sound. Whine AND whistle, AND it's proportional with throttle. Now, they COMPOUND boost, making them not so great for bottom end[from what I've read on how they function, IE at half your redline, they'll only put out half of your desired max boost], BUT, there's zero lag because they're belt driven. And centrifugal. Basically, a belt driven turbo.

I'm sure you know about them as well, but I can't help but sare my enthusiasm for this newfound love that I'd initially written off due to the way they functioned and 'lacked' low-end grunt. But with turbo lag, boost threshold, and THEM generally lacking low end when built for insane boost and big power, I figure a linear/exponential belt driven equivalent should be a little better, as well as simpler.

Plus the sound. THE SSOOUUNNDD!!!!

EDIT: What I'm saying is, don't spend time and money building two motors. PROCHARGE THE 468, DUDE!! At least when you're ready to move on and double what your current projected output will be. Or more if you get one of the EVEN HIGHER END prochargers in the F2 or above range

I don’t want to deal with belt slippage, I can swap to a 8 rib set up but even then there is bet slippage, but not as bad as a 6 rib pulley. I can go with a cog set up as well but that’s a lot of damn money. This guy Andrew has a 438 hemi with a F1 and spray and barely made 1000 rwhp, he got tired of the belt slippage and went with a cog set up and was happy he needed boost and nitrous to get 1k. So he switched over to turbo and is now at 1200 rwhp and traps 149 mph in the 1/4. That’s moving! I love me some procharged as I had one in my garage but just don’t want to deal with belt slippage, now don’t get me wrong cause if I find a deal I can’t resist then I’ll jump on a centrifugal or even a roots style blower. But if I have to pay full price I’d go with turbo instead. Also go such a big cube motor as the 468 a P1 will be spun to much for a big motor causing producing a lot of heat. I’d need like a F1 as well and those are close to 8k if not more.

The problem with boosting the 468 is that rod angle is a bit to severe to make it reliable for boost. It can be done but just slapping some forge piston and rod on a 6.1 and keeping it at 370ci and just give it a lot of boost and it will make hell of good power with my heads and Intake I have on the 468.

Rib belts on a SC is a bit of a problem. I converted to 8 rib on my 03 ram. The datalog shows no slippage @14psi. but I'm confident its slipping under certain conditions. I copied Charged392 belt tensioner and IMO it is as good as it gets for rib belts.

Nice! How much was it to switch to a 8 rib?

How about a D1X? That's the highest tier on the Procharger website without looking at the "racing" models.

And I bet you could get a cog pulley set made custom for a decent price and get an off the shelf belt that'll work.
