building 400 sbc

I have a stock 76 400 sbc in good running condition,i want to pu it in my 69 Acadian,it has a t350 trans with 308 gears, i want to put 3973370 64cc heads on it with a adelbrock intake & 650 edelbrock carb,these heads are the same as 186 heads.i won,t rev the motor over 4500, it,s a driver not a race car,the heads are stock with 194 150 valves. what compression will the motor be,it had 76cc heads.what is a good cam for this motor,im looking for decent milage for a driver. the original 307 2bbl gets about 17 mpg hwy. if i could get the same with more power that would be a bonus,it has duel exhaust also.all info appreciated,Im not touching the short block other than new oil pump ,double roller chain & gear & lifters. cam?
