Hi guys,

My factory manual doesn't have the specs for the cam timing for the 2.7L engine, just the 2.5L. Something like intake open 1 deg after tdc, intake close 49 deg after bdc, etc. Anybody have those numbers? Or a pointer on where I can find them?

Somebody said they are the same as the 2.5 but I thought they were a bit different.

Cris I have these specs for your 2.7,
Intake Opens 1 degree. after TDC
Intake Closes 49 degrees after BDC
Exhaust Opens 47 degrees before BDC
Exhaust Closes 1 degree after TDC

Thanks Bill!

Are these the same as 2.5L?

TP

Tim, not according to my book. The 2.5L is as follows:

Intake Opens 1 degree. after TDC
Intake Closes 49 degrees after BDC
Exhaust Opens 43 degrees before BDC
Exhaust Closes 3 degree before TDC

Bill, BTW are you sure all the 2.7 values are after TDC?

Cris, the specs that I listed are for M44/05 to M44/12 engines. Some of these are 2.5(1985 and up) and also the 2.7. The specs that you listed are for M44/01 to M22/04 engines which includes 2.5's up to 1984.

Thanks for clearing that up Bill.

Those would be the specs for the 09 cam versus the 05 camshaft from the earlier cars. Greg F

So to clarify.....late 944 85.5 and higher 8V 2.5L and 2.7L 8V have the same cam?

Intake Opens 1 degree after TDC
Intake Closes 49 degrees after BDC
Exhaust Opens 47 degrees before BDC
Exhaust Closes 1 degree before TDC

This produces a 2 degree overlap

True?
