Your engine stock,should have had approx 10.5:1 compression.Your aluminum LT1 heads have 54cc chambers & flow around 212 cfm as is with 1.94" & 1.5" valves.Some porting & cleanup.Maybe up the valve sizes to 2.02 & 1.6. They would probably easily support your HP goals.If the pistons turn out to be the shorter version,your CR will be slightly lower.The overbore will also give you a slight increase in CR.The stock injectors are rated @ 23 to 24 lb/hr.I can see you making 400 HP relatively easy & still maintaining good drivability.Getting a good PCM tune would also benefit you a lot.
