I'm running the cilfford hot water heated intake with the tbi adapter on it. The 261 had a theromstat bypass hose so i came off of those ports with stainless tubing to the intake. There is a web sight that has a winALDL program that you can down load for free. With this, a lap top and a cable. That you can build or buy. You can hook up to the ALDL port. This lets you look at what going on with the control system and has a data loger so you can store and look at the data. I,m going to do this but haven't got to it yet. I'm hopeing that I don't need to reprogram. The 4.3 is 265 ci. and my 261 .040 over is about 265. The fuel and timeing tables should be close. I used the dist. out of the 4.3 .
