Correct TBI adapter plate for GM Truck?
Hey guys, can someone tell me which adapter plate I would need to install a 4 barrell intake on my 350 TBI in my 1990 K5 Blazer?
I want to put a performer RPM or a Weiand Stealth on it, but noticed that there are many different TBI adapter plates, and it has to do with the mounting location of the TBI unit, either forward or backward.
Anyone done this before? Is it the same as on the f-bodys?
I tried a search, but couldn't find what I was loking for.

No changes were needed on the throttle cable/trans kickdown/ or the bracket for both with this center mount adapter?

Re: Correct TBI adapter plate for GM Truck?
I guess it all depends on your usage and dedication to tuning!! I live in B.C so the winters are not that cold! -10 or so this year. Yes there is some fuel dynamics that have to be dealt with with a cold intake, but you have to deal with them with a carb as well. It can be just slightly rich if its cold out for the first 5min or so and there is a little bit of playing around with cold and hot AE and Pe settings but once I got it close it was fine!! Runs way better than my carb ever did and better mileage to! It is less work with a heated manifold but I like the Air-gap!! If your not into being addicted to tuning then run a heated manifold! Also it would be easier with a IAT sensor that the cars have- Mines in a truck. All in all I like it though. Hope this helps a little?

Well, I live in Hawaii, so I guess cold fuel is not something I will ever have to worry about, unless I take the truck to Mauna Kea, which is still not even below 0.
