Are you staying 3.8, or going 4.2. Bottom ends run about $3k done properly. Crank, rods, pistons, bearings, studs, etc. If he is porting your heads, is he installing larger valves? A cam is about $350.00, push rods $100.00, rockers run about $450.00, and springs $150.00. This is without touching the upper/lower intakes or machining your heads to accommodate the springs, new oil pump $100.00, timing set $100.00, etc. This is not including machine shop work, or balancing the whole rotating assembly. you cannot build a performance motor to stock specs. Clearances need to be different or your motor will not oil properly. That's why motors are so expensive to build.
Just some food for thought.....
