2.8 vs. 2.9
I have a 1985 Bronco 2 and the guy who sold it to me said he put a newer engine in it. It doesn't say anywhere on it whether it is a 2.8 or 2.9. It is a 6 cylinder. Are there any quick references on the intake or etc. where I can tell what motor I have so I can change the head?
Thanks

Easiest way to tell is to pull the valve cover(s) and see if it has hydraulic lifters or solid lifters. More than likely if you're replacing a cracked head.... it's a 2.9... I'm guessing. Anyone know what casting numbers to look for on a 2.8 / 2.9 to tell the difference?

You all do realize that you can interchange the 2.8 and 2.9 intakes, right.... the previous owner might have saved himself some trouble and put the carb on a 2.9.... the only differences between the two are the timing components and the lifters, as best that I can recall

I thought the lower intake wouldn't swap but I never worked on a 2.8, can anyone else comment on the fit???

2.8 vs 2/9 vs 3.0
Someone told me the 3.0 Tauras engine is the same block as the 2.9 Ranger engine. And will bolt after changing intake, is the indeed the same engine?
Seems there are alot more of these avail out there.

I've heard guys on some of the other well known Ranger forums who had to give up trying to interchange 2.hate and 2.9L components. I don't think the accessory belts even spin the same direction and the ports don't line up on the intakes, among other issues.
Why you'd waste time with either engine...beyond any of us.

My main drawback, other than valvetrain components lacking, in beefing up a 2.9 is the fact that headers are too damned expensive (unless you're doing a 2wd rig). Other than that, there are several things that can be done to these engines -- which is why many people want the book by Sven Pruett "How to build and modify Ford 60 degree V-6 engines"

I'm half-tempted to physically look at the 2.8 and 2.9 camshafts to see what the specific lobe layout differences are, unless I can find the technical data somewhere. The main reason for this is that Competition Cams makes aftermarket parts for the 2.8, but -not- the 2.9... (my question is, does anyone make a hi-perf. cam for the 4.0??? .... )
