Hey everyone I am a newbie on here but I am in the process of a 455 build up on a 1966 cutlass with a 1968 455. Anyways I am trying to get ahold of a intake for this motor that a edelbrock 750 would fit on to, so a edelbrock mani would be great. also I am in conflict about what cam should be with this considering a generally a stock bottom end rebuild and stock c heads? Headers, 750 cfm,about 3600 lbs, 3.08 gears. I have been looking at mondello jm-20-22 which is .226 .230 dur at .050 with a .496 and .512 lift ...... Does this sound good for ultimate street or will I suffer from low end blues?

 

 

Welcome to the site! I like the performer for all around driveability and power. It also has the dual bolt pattern so you can use either a spreadbore or squarebore carb on it. Sorry, I don't know enough about cams to comment, but I know there's some members here who do. Hopefully you'll get some help from them soon. John

 

With 3.08 gears I'd step the cam down a little bit. Something in the 218-224 duration range would be more suitable in my opinion.

 

Thank You for the input
