454 vortech power and torque numbers and AFR

[John Cunningham]

No, I was saying I needed to send payment to get it, all I have from him is the spreadsheet for now; we've been going back and forth on getting the tune worked out and I just don't have the money to order it right now.


He does give away the pinout for free; but like L31MaxExpress said he asks people to not redistribute it.

Ok I got you.......if you do email with him........I would like to but the pcm and pin map

I have a weird thought too. Why not a PSI 8.8? It is based on an 8.1 that has had the heads and intake manifold changed for maximum low-end torque. On Propane they make 565 tq @ 1500 rpm and 270 hp at 2,600. On gasoline they can make about 10-15% more power and torque. It has a fully fprged rotating assembly that is rated to take 1,000 ft/lbs.

Those are the numbers I am looking for

With regards to the 0411 conversion, does going coil near plug change the pin out drastically or can it be done later without much fuss? I'm preparing to swap my 454 over to 0411 but I'm not sure if I should go coil near plug right away or not. I just spent money on a new dizzy and wires. Wondering if it is worth going cnp for my mild mods.

my guy has the hp tuner software...he does not have efi live ..not now anyway. I called blackbear and also my tuner said if my truck was a 98 we would be in luck or a late 97 and my truck was build 12/96

Your right....the tuner I used said he can tune a 98 or even late 97 with HPT...my truck was build 12/96 labeled a 97 model

He can be reached on LS1truck I think; it's a free account on there and he got back to me within a couple days

I think the most likely place to find one would be in a school bus.

School Bus, Medium duty truck, Generator or Industrial applications. They are starting to show up used now.

I meant to reply but got side tracked. Adding coil per cylinder to an 0411 swapped setup is not hard at all!

Thanks for the encouragement, now I'm just debating to do it all at once or wait until I need another tune up.
I guess I'll see what my local Dyno tune guy has to say.
