Tech1, when oh when will I get my engine running? I am coming to the end of my wife's Florida room project and hope to get the engine running this summer. My comment has to do with the Crane cam I have (Crane 10010, 194/204 @ 0.050" and 260/270 advertised duration with 0.398/0.420" lift, surely a mild cam BUT it is listed with a 104 degree lobe separation. Does the narrow lobe separation lead to a stock-like idle or some rump-rump? I can't wait until I can get this new room project out of the way to get the engine running, but with the 700R4 originally recommended by Tech1 it should run strong up to 4000 rpm and the OD should run OK at 2000. I just made a quick run to/from Charlottesville from Richmond on I-64 last night and the gearing in my Sunfire is almost exactly the same as my roadster with a 3.55 rear and 700R4 and running at 70 mph most of the way showed about 2500 rpm in the Sunfire so the cam in my 350 would be running at 2500 a lot of the time and that is where I would like plenty of PEP(!) to accelerate from 70 mph (occasionally). Man this building takes patience and lots of $ but I want to DRIVE the roadster! Good to hear from Tech1 again!
