I agree, Joe and Roger were very helpful when I was making my cam selection, and continue to be in my search for a new cam after I get the new heads on the truck.

I'm not looking to start a flame war over what cam is better, but my "baby" cam stacks up pretty well against some of the bigger, more popular cams used here and my torque curve is flatter than Debra Messing's bustline. Yet for some reason, they get no respect.

 

Now that's some funny chit right there!

 

yea, I think the ultra tq/rockers are going to do it for me. I CANT sacrifice any bottom end, and the biggest converter I go with is going to be the TB. time for me to give them a call to get my truck there within the next few months..

 

400 ft-lbs from 2700 to 4700...not too shabby....and my tune needs lots of work too. I'm sure it's great below 2700 as well, but that's the RPM I started the pull at...

 

I visited Vincis shop last week. Met Roger and Joe. Roger seems to think my Magnacharger should be running at 12.6 to 12.8 AFR. What do you guys think of that? And yes, I told him I was pushing 8#'s of boost. Roger still thinks 12.8 with 20* would be a good combo for my truck.

 

He's right that 12.6 to 12.8 AFR will make big hp numbers,but it doesn't leave any margin for safety.The leanest mixture needed to produce maximum power and highest timing before the thereshold of knock will produce the best performance,but that does not account for running in summer heat and traffic.12 to 1 AFR is probably safe.

 

When I was topping out at 12.5:1 my 5.3 popped #7. The 6L I just replaced was runnning at 11.6-11.8 and is still broke 4 piston rings. So I dont know whats going on. I just got EFI live and will be looking at my tune, as soon as I figure out how to pull it out Running 12.6-12.8 in FL in the summer without meth seems like youre begging for trouble. Roger said they do it on vetts all the time.

 

I thought 11.5 was the best for FI?

 

Not sure if you ahve done this yet are not as this is a little older post...but don't get the TB stall.Its a waste of money.It cost 324$ from teh dealer for a TB stall and you can get a Yank 2600 for 375$
I ahd the TB stall for one day and got rid of it.Its so freakin loose it will drive you crazy.It stalled to about 2400 and flashed to 2600 but just tryin to drive it would roll about 2400 with very little pedal just annoying as hell.
I got a Yank 2600 same stall speed and love it.With normal pedal it never gets above 2k and isnt at all as loose and sloopy feeling as theTB stall.IMO don't waste your time with a TB stall.
