I've got the 306 in my 3rd gen. I bought a 92 suburban lifted on 35" tires and wanted to give it more kick. It's got a 60,000 mile gm crate motor in it. The TBI has 310 cast on it. It also has only 3 vaccume ports on the front, versus the camaro's 4.
What is the difference? What lb/hr injectors did those models come with?

Thanks!

 

Oh come on.......





Seriously............

 

The suburban and f-body should have the same size TBI but with different injectors. You won't gain anything by swapping units. It would be easier to just change the injectors and do the chip work to make them work proper.

 

I am going to swap on the camaro's tbi, with the burban's injectors, since I've already "ultimated" the one on the 'maro...

I read someone's post where they called the ultimate tbi mods the "unlimited" tbi mods.....Sounds cooler

 

The thirdgen TBI unit is different from the one on my FSC.

The ONLY diference I have been able to determine is that extra vac port. I misplaced teh vac diagrams, but I'm sure it only for something relatively unmeaningful (like the little flapper in the stock air cleaner or something along those lines?)

Other than that the units are exactly the same, don't worry about capability problems for modification.
