2.7 Six conversion questions, Oil cooler and motronic Options

[bigkensteele]

Topic 1: Has anyone ever tried mounting an oil cooler under a GT lid just above the fan, and if so does it keep the temp low enough for DE events?

Topic 2: Has anyone here ever adapted motronic from a 3.2 to work on a 2.7? If so, what is involved? Which distributor? What cam? Stock low compression CIS pistons or JEs?

Topic 3: What kind of power can I get if I keep the CIS but am willing to port the heads, change cams and go to JE pistons?

Please feel free to address any or all of the above? I have a '74 2.7 core that is currently torn apart and ready to send out for machining. It already has case-savers and nikasil jugs, so I am going to stay at 2.7. I have all of the CIS parts, so that is an option for induction, but I would rather do something else (other than carbs).

I will also be running stock 6 heat exchangers and a 911 muffler.

I just can't bear the thought of rebuilding this thing and only ending up with 150 hp, so any tips would be most appreciated.

I have a set of the Crane GE60 equivalents, but Bruce Anderson says that they are too much for a 2.7, so I am leaning toward a 964 grind. I am budgeting for 9.5:1 JE pistons rather than running the stock 8.5:1 CIS units. I did get lucky because my jugs are nikasil, so hopefully all they will need is a nice hone.

My hope is that if I bump up the compression to 9.5:1 with JEs and swap in 964 cams, I can get somewhere around 200hp with the Bitz MS kit and keep heat with the new Stoddard exchangers.

While I am in there, I will probably do the oil bypass mod if I can find a new pump. I may even try porting the heads with my Dremel. They are currently 32/32.

I can't find any local machine shop that I am comfortable with, so all of this is probably going to be sent to Ollies in AZ, unless someone can recommend an east coast shop.

Thanks,
Ken

I recomend Craig Garret (Cgarr on Pelican board). He just did an excellent job on a set of heads for me. Ported 32 out to 36. He also does case savers and the bypass mod but he does not do line boring.

At the very least, talk with him about your heads. He is very reasonable, does great work and is relatively quick and is very easy to deal with. At his prices, I would not screw around trying to do the ports yourself unless you are looking for the experience.
