Sounds like a Plan, AND A DAM GOOD ONE

Richies runs a 3.7 (or is it 3.75) upper + 4lb lower and makes great power
Mine came with a 3.0 upper and I had a (well lets just say i run a "larger" lower pulley)

Over the weekend I plan to pull A LOT of Boost from it, as said I highly recommemd you do the same. DON'T WORRY YOU'LL STILL HAVE MASSIVE POWER

 

Why don't you wait until you are ready to install to order the SC ??

If it is like most things, the price will only improve with time and any newer changes or happenings will be in place when you buy.

Just a thought...

 

If I dont buy now then I will prob blow that 3900 on other mods.

 

blow that 3900 on upgrading the short block and valve springs, then crank up your stock blower.

Then next year, upgrade the rest.

I dont' understand why people change blowers, pumps, maf, and run a stock block with stock heads, valve train. There are a lucky few, but if you aren't prepared to fix it when it breaks, then start from the ground up.

If i had 4k to spend, i'd do at least the lower end first, then do the rest. I upgraded my pumps just because i was gonna pull them to make sure my clamps weren't falling off.

I tried to upgrade the Maf........that's a whole other story.

Said F'it.

Spend the money on a lower end first. Then you can sell your stock short block and make a few bucks if it has such low miles on it.

Good luck at what ever you do.

 

thanks tall, Still dont know what to do.

 

Anybody remember when a 2# pulley was pushing your luck?

 

i dont go back that far,,,heck im just a pup still

but i do think we are capable of running a stock bottom truck into the 10's now

 

Right, and that was when no one knew anything about these lightnings and the 5.4 mod moters were fairly new to the aftermarket performance world.

We've made strides in tuning and technology.

We know what these stock blocks can and can't handle.

Why put on a KB 2.6 is if you can't reap the benefiets of it.



Upgrade your motor first.

Would you build a second story on a sigle story house on a foundation that was crumbling?

 

Hide and watch.

There are guys finding out just what the stock block can take, instead of just theorizing and preaching about it. The new SCT MAFs have only been out for a year, and the Whipple less than that. Tunability is better now. Detonation is, and was, the enemy. I'm running a safer tune now than I ever have, and making more power by a long sight. The engine can take more than we previously thought. The transmission, however, did not make it.

 

Hahaha...I remember that! People had 1lb pulleys. Then 2lb'rs hit the street. And then a 4lb pulley was for "race trucks" only! The tuning and support for these trucks really has come a long way considering their limited numbers. I remember the LS1 guys saying how weak our motors were. Now 500hp on a stock block is VERY common. How many LS1's could do that, espesially pushing a 5000lb brick!

 

I am going through with the order next week, and going to push my luck. Thanks for the input guys.

 

Amen to that man. I wanted a lightning for a long time. I passed out on it becuase of people saying that it can barely handle a pulley upgrade. I had a 99 sherrod. Love it, that got totalled. I got my 01 lightning this may and havnt looked back. Im hopeing the 3.3L whipple makes its way out soon. Ill add that to my truck this summer and tune it to see what it can take. If the engine fails, then It will be time for a buildup.

People are going to soon realize that even built motors won't be able to handle a 2.6 KB or for that matter the boat supercharger 3.3 Whipple. Not that the block will blow up, but the amount of boost going in won't net any gains and probably will make less horsepower than a 2.3 KB or 2.3 Whipple would. That means major head work and cams matched to support the race chargers.

 

Interesting, that may be the problem with the 2.6 2 much

 

bigger lift on the cams is all you really need,,,,too much lift was always a problem with the little kb

the bigger kb and the whipple 2.3 can support bigger cams
