Hi guys. I thought I would put up the question up in here, since it seems that people in here are not so hung up on the usual "choppy idle is all that matters" junk.
I need advise regarding cam choice for a Buick 430. It is 10.25 cr, and it gets stiffer valvesprings and dualplane edelbrock aluminum intake ( for some reason, car is not mine )
The engine sits in a 1967 2-door wildcat and everything stays stock.
I want to put in a cam that takes advantage of the high cr, but does not have miserable idle.
Owner of the car suggests these two lunati cams.
Advertised Duration (Int/Exh): 262/268
Duration @ .050 (Int/Exh): 219/227
Gross Valve Lift (Int/Exh): .484/.505
LSA/ICL: 112/108
Valve Lash (Int/Exh): Hyd/Hyd
RPM Range: 1300-5500
or
Advertised Duration (Int/Exh): 268/276
Duration @ .050 (Int/Exh): 227/233
Gross Valve Lift (Int/Exh): .505/.521
LSA/ICL: 110/106
I am worried about idlem with the LSA on the latter... But I guess the high compression will compensate somewhat for this?
Feel free to suggest other cams.
