Re: 4.3 tbi to 3.4 on 2.8 manifold
On rereading my post I thought a little clarity might help. I have removed my 2.8l engine from my 86 jimmy. I have purchased a 3.4 from a 95 firebird. I have removed the manifold and multiport fuel injection equipment and accessory brackets from the 3.4 in anticipation of swapping in a bored out 2.8 intake manifold and the 2.8 accessories. On inspection of the 4.3 used TBI I have noticed the throttle hook up is a little different from the 2.8 TBI. They appear to be opposite to each other. I have read a few posts here and elsewhere suggesting a solution involving grinding down the cable but I can't picture the solution. Everything else seems to be falling into place, ie: 4x4 oil pan and timing cover to fit, water pump, intake manifold, exhaust manifolds, distributor, sensors. I would like to thank everyone here for contributing their time and knowledge for "the greater good". One thing I will remember is to retorque the intake manifold after bringing the engine up to operating temperature. If anybody can help me to understand how to work the TBI hookup I would appreciate it. Thanks, Jeff.
