So what would you folks recommend me to go for, MPFI or TBI setup for my truck?

I don't believe the blackbox is easily adapted to TBI. I would opt for mpfi.
Yes, you are right, blackbox is a pain in the ass..., i mean, off course it is possible to program, the programmer i go to, is using EEPROM to tune my chip. However, even for him, he needs to make change and try the car, then again and again... (((, truly i want to swap to 411 with roadrunner, but don’t know if i will be able to tune it myself and make changes to settings, how difficult it is and what knowledge i must have. With EEPROM i am sure i am not capable of doing it!!! ((
Found this manifold: http://www.michiganmotorz.com/mercru...nt-p-4576.html, if i don’t get the used one, from the service that found me two different manifolds, will probably start saving for the one from the lint, nowadays with the FX rate, plus shipping costs (and i guess it weights a lot), the prices in $ really bite...
That manifold has the 4 bolt drive by wire throttle body. Might be a concern there as the Vortec and LS cable are three bolt.

Yes, you are correct! Thank you!, I didn't notice it, all thaw it comes whith it's own throttle body, but don't know if it will work. Thank you for pointing this out for me, I have to be more attentive!Originally Posted by brian617
The L31 uses the 3 bolt t-body. If you want to retain your stock cruise control along with the stock you need to run a t-body spacer to clear the passenger side fuel rail, or slightly bend out the tab on the L31 throttlebody. The Ramjet intake can be had as well, but the Marine Intake is the most complete, easiest conversion there is. This is all covered in the Marine Intake Bible. point #5. http://www.pacificp.com/forum/viewtopic.php?t=317 Why are are you wanting the MArine Intake, it does a dd a bit of power, but not worth doing the swap for that alone? The only reason I did it was to be one of the first to do it. peace Hog
