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. |

Thanks to all for the responses. I was looking for more seat of the pants and personal experience opinions/data than what I have found in the Anderson and Dempsey books, and you guys have provided that.
My vision is a bit more clear. Leaning toward the Bitz MegaSquirt kit with a custom air box, trying out the GE60 cams that I have with JE 9.5:1 pistons and having the heads ported a bit. This should put me close to my 200 hp goal without spending stupid money. I am still thinking that the external cooler is going somewhere in the back of the car and finding out at the first DE or AX if that is going to work. One more question - I am not sure that I want to weld an O2 sensor bung(s) into the new heat exchangers that I plan on buying. Would a bung or bungs in the muffler work? |
