Alright! A good solid debate. Let's get to it.
Wayne you say your 2.7 runs pretty cool and not at all. A conundrum.
The racers run early aluminum case,but B. Anderson says it's not as strong as the 7R case.
The 2.7 pulls studs but the 3.0 breaks them.
The 2.7 is easier to install in a teener,the 3.0 is better but heavier.
External oil coolers are/are not needed.
Smaller(2.4 & below) are more reliable but not as much fun.
3.6 would be great but cost as much as a solid 73 911T(trust me)
Missed the 3.2. Let's lump it in with the 3.0 but include it's proclivity for eating valve guides.
If I've missed I'm sure someone will point it out.
OK,where to start. At the begining. Is the 2.7 AFG.
I contend that nearly all its problems are heat related and can be dealt with or in the case of the original post, have been if done properly.
Mr Anderson says that Porsche added oil coolers to its 911 when the hp rose above 160(as I recall). Sixes run hotter in a 914. Go figure.Forgive the spelling I am in a hurry.
Next.
