I am gathering parts for MY car (for a change) which I hope to start on next year. I will be building a 2.7 maybe (probably) with Je pistons. Weber carbs but not sure what cams to go with. E and 964 cams seem to be the most popular, but which is better? I would like real world opinions please. Is one better with stock pistons and one better for JE's (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) Thanks for the help (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif)

OOOops! Missed it in TimT's listing of recommended cams (sorry). we haven't forgotten the Solex cams, we just realise that they're hard to find new or serviceably used. if you're going with reman cams from WebCam (for instance) it's a nice profile - but like the S profile, it's got too much lift for a stock CIS (or 911T) piston. with aftermarket pistons it's a contender. My engine was originally a 2.4 T engine. When the swap was done to 2.7 liter pistons and cylinders, the cam was left stock. Later, during a top end rebuild, the cam was re-ground to Solex specs. Should be easy to do with any cam (I think?). lots of people like the early S cams in bigger engines. it had a reputation of being peaky with 2,0-liter displacement, which it was, but a 50% displacement increase adds in bottom-end the 2,0 engines never had. Exactly. Bruce Anderson recommends rebuilding a 911 engine with an "S" cam after you reach 3.0 liters of displacement. With the way my 2.7 engine feels, and the modifications Scotty B is doing to his 2.7, I think an "S" cam would be a great choice. |
