Maybe this will help you. https://www.thirdgen.org/ecminterchange I'm sure this has been answered before also. Do little searching and you will find many conversions. By the way this is Jason

Re: ECM interchange
Just picked up 86 ecm. Has anyone ran one of the holley stealth rams yet? thats what im leaning towards. they tested it on a 3rd gen with a stock 350 prom, a mild comp flat tappet, and 3.42 gears and it ran high 12's. Thanks for the info, its greatly appreciated!

Re: ECM interchange
Here's a entire list of posts dealing with this https://www.thirdgen.org/forums/sear...archid=4303175 there is also probably more remember that search is or could be your best friend. If you think of a combination odds are some people have already tried it and posted it. By the way you have two 350's right? do they both have L98 heads and are you thinking of selling?

Re: ECM interchange
Will you be selling one of them. The 383 I was going to build had vortecs on it you can make 400 HP with vortec 350 and a little work.
