I have a similar problem. At the moment I have a Holley 850DP on my 427 co stroked to 482. However, one of my winter project is to switch to 4 Weber 48 IDA. I have Edelbrock heads ported similar to Stage 2 and the C.R. is 11:1
The present cam is a mechanical roller, Crower 301R, with 258/264 @ .050, .663/.675 lift, and 108° lob separation and it is probably too much. But I would like to try it before I order a new cam.
I mailed both Keith Craft and Barry Rabotnick. Keith Craft recommended the same cam as above. Barry R. wrote that he to would like to try my present cam first.
I have been looking at Comp Cams 288R with 248/248 @ .050, .645/.645 lift, and 114° lob separation.
Priobe, what cam is it you want to buy? I cannot find it on Comp Cams site. Is it a custom grind?
Right now I have the transmission out of the car and I have removed the side pipes. So it would be quite easy to lift the motor and change the cam.
But I will probably first try the Webers with the cam I have. If it does not work I will go back to the Holley and buy a new cam and mount it next winter.
