I got my motor back
Well here is the situation,, I got my motor back and all looks good. I need to find the cam I want and so forth and then start assembly. I appreciate your input and so forth as I was really concerned about my cam selection. I have a shot at getting a XM264HR from Salee Cheverolet on ebay and I think I may just go with it. Its not going to rumble but ought to be strong none the less. I have dished pistons speed pro H815P installed on the rods. I have yet to figure out what kind of rough compression ratio they will get me.. I believe they are stock replacements so that should still yiel 9 to 1 with 64cc chamber. I will check back when I get this info and get a cam.. I am going to stay on the mild side of the cam situation and try and get as much torque as I can.

Short duration hyd roller cams make less torque/pwr than short flat tappet cams. It a characteristic of the lobe ramps. If hyd roller use >270* full duration.
If <270* and u want torque try a single pattern cam like Comps 270 Magnum or Isky's Mega cams with 108 LSA - a bunch cheaper too.
But nail ur c.r. first as that will determine how much overlap to use with ur cam choise.
Plenty of recent posts on quench and u should read those too as good quench will allow 9.2-9.5 c.r. on 93 oct gas with iron heads (again depending on cam overlap) - or 10.2-10.5c.r. using aluminum heads BTW. And higher compresson will produce more pwr also for the same combination of parts.
But hey if want to brag a roller then do it and enjoy/be happy.
