My bad, I wasn't using Wallace, it was some other one, a cording to Wallace it says pretty much what you're hoping for, it predicts a 10.86 1/4 mile based on your 1/8 mile et, but says u should be around 122 mph  !
You're at 113mph, where did 9 mph go? Is that your coils not lighting it off properly once the boost gets to high or just the pure size of the truck pushing so much wind like you said in your previous post?
Thats what I'd like to know. The HP went somewhere  The engine is still pulling, but not hard like it should. You can feel it start to lay down around the 1000' mark. Even with my bad aerodynamics I should still see a higher mph trap speed.

I'm going to end up with a 223/227 112 with .610 lift through a 1.65 rocker. Stock 6.1 block with ported eagle heads and a custom gasket.
I'd be happy with 450rwhp through a 23 spline. A similar combo went 11.15 at 119 in a 4000 lb magnum with driver. Sub 3500 lbs with driver like my car will be more than enough.
That thing will fly and pull a camper van on weekends!!!

It won't make the power you want in the upper rpm range that you expect. 
Do you think 460 at the crank is achievable?
If I was a betting man, I'd bet you'd see close to 500. 
Anywhere near that with just a cam upgrade will do me fine!!

With the drag pack cam, (229int 236 ex duration, 110 lobe seperation) what kind of torque curve am
i looking at with a 3.888 arm? Any idea where to install it? My guess is start at 104? This will be a street motor with the Edelbrock dual four combo and two 500 cfm carbs, SRT8 jeep manifolds for exhuast.
Thanks very much to all those that have contributed, and keep it coming.
One thing I heard was the motor should be pre oiled, can be done through a pipe plug by the oil filter mounting location . Anyone care to add to that ? (equipment, does the motor need to be turned over, etc)
Your cam in a stock bore, stroke 5.7 12.5:1 comp with DP intake manifold. Cam was all done at 7000 rpm.
Edit...Wrong dyno sheet. I'll find it in a bit.

Custom slugs with that..yes?
Or doesn't the 5.7 suffer from the same issues as the 6.1 on the intake side?

Yes to the piston question. Also remembered you have a stock 6.1 crate engine....forehead slap....

I hate that it's just sitting there too but I don't have any input
And totally agree with your comments re: boost vs. hp as well. Ours should have ran harder IMO and there were a million things to evaluate that never were. We needed more time with it.

Oh, and since this was supposed to be about posting things to avoid....avoid using O ring intake gaskets with a carbureted app. Even though the carb intake may have provisions for those nice O ring seals, they deteriorate really quick when exposed to gasoline.

This is a worry.  .........Can you recommend an optional part # for a replacement gasket?

MP15 gaskets...The pink ones. I think Summit carries them.

 I made my gaskets from MP 15 material. The MP 15 is the type of material Interface Solutions sells. The material is available from Superformance Gaskets/Greg/sponsor here on Moparts.com. IHTH

If a guy was gonna start from scratch with say a 6.1 block and eventually put it in an A body, would it be an expensive deal to acquire the necessary accessory brackets,sensors, trigger wheels etcetera to get it to pop? I have a Fast EZ efi on my BB now but it looks like the intake that has decent fuel distribution is $900 too. You can get a block for right around 1K and I would build a 426 anyway but a complete 6.1 is usually 5K plus. I would probably grab some Apache heads from the dealer as well. What would be the smartest approach to building this thing is you're starting with nothing?

I feel sure you'd outlay more than the = LA small block.
G3 bits appear to be a little on the high side for some stuff.

I did all the math and decided to just buy a new 6.4 replacement engine. Looks like prices went up a couple hundred bucks from when I bought in December and the harness isn't included anymore.
I received a complete automatic engine with exhaust manifolds for $5,703, no core charge. Great deal to me compared to piecing all the parts together. I only want to make 550 at the crank with a cam swap and headers, so it should be fine. Going to run the 2009 computer for the VVT and eliminate the MDS.

P5153757 works well for for 5.7L, and they're the pink colored material folks are referring to as well.

Why did the price of a set of 4 non mds lifters with yoke jump in price to $167? Even the non mds yoke alone is listed at $167 without the lifters!
What gives?
