427 FE What do you think?????

I like the ones with the secondary metering blocks---those metering plates are a pain to stock---I want to use jets--there is a kit that you can get to convert your carb

Yes, a lot of people feel that way. Although I have to say my 4160 runs perfectly and the 750CFM gives excellent throttle response. Priobe, when I wrote "adjusting anything on the secondary side is a real cinch" that was "carb humor." You can't adjust anything on the secondary side of a 4160, except when the vacuum actually opens them. All in all, it's a very simple carb, but it's been a stalwart performer for decades.

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.
