Punching the block, hot tanking knocking in new cam bearings, resizing the rods and grinding or polishing the crank will set you back about$450 plus a valve job for an extra $180. A seal power kit from summit is another $380 and throw in a summit cam and lifter set for $110.
add oil and breakin lube you will be at around $1200.
People have their own opinions on 318's but I think the biggest mistake I ever made was swapping mine out for a not so stock 340 4 speed.
