Estimated power of 3.4L?
 

I have the opportunity to acquire this motor

What kind of power numbers should this combo put out?

"3.4L engine: 930 case/crank/rods, ported and polished factory heads (twin-plug), Crane racing springs, large stainless valves, bored factory NiCom coated cylinders, Webcam high torque racing cams similar to G-80 grind, Ross 11:1 pistons, Electromotive twin-plug crankfire ignition, Weber 46 IDA3C carbs, GHL Motorsports s.s headers 1-3/4" O.D. with GHL s.s 2 in 2 out racing muffler, balanced and blueprinted"

That's all I know for now......any good guesses? 300hp?

What is this engine worth (33K on motor, ZERO miles on re-seal)? $12000?

Do a search under RDane. He built a 3.4 CIS motor. I believe it put out about 260 hp. If you factor in Webers, hot cam, hi-comp pistons, etc., sure - I bet close to 300 hp is possible.

I would think $12K is a good deal considering the work that would go into building a motor like that.

Very nice, BTW. :)

You would think that, until you learned who built the motor. See the crossposted thread in the 911 forum.

IMHO, the bored and plated cylinders and Ross pistons are a cheap alternative to the Mahle Sport pieces. I wouldn't expect the same longevity from this build as using the factory stuff.

Run.........Forest, run !!

I have just finished tuning a 3.2 with Autronic, triple throttle bodies, twin plug heads, 11:1 compression, this engine showed 280hp at the flywheel. The power curve was very jaggered though, indicating a lack of traction,which would have reduced the indicated power. In reality it is probably closer to 300hp! Considering this a 3.4 with bigger cams, should be closer to 330-340hp!!
