After some soul searching and number crunching I've decided to keep the 292 in my '55 Merc. I got a good set of '57 B heads with the matching 4 barrel intake and exhaust manifolds to replace the restrictive '55 pieces. I could just swap those out and get a fairly good HP increase, but I suspect the cam that's in there now may be damaged by the PO setting the valves at 0 lash. I don't know how long he ran it like that before I got the car, but a vacuum gauge indicates a possible burnt valve or 2. So, I'm soliciting suggestions for a good grind for this rig. I'm looking to move the torque curve a tad higher in the RPM range, don't want anything too radical. The car weighs about 3600#, has a T-85 with OD and a 4.09 axle. I figure with that ratio I can afford to swap a little bottom end for more torque at normal highway speeds. Would also like suggestions for the advance curve.
