picked up my V8 yesterday,did a compression test this morning,while it was cold....number 6 was 95 and number 8 was 45 psi,the rest were bout 150 psi,im gonna do rings but i was thinking wether to do bearings aswell,can you get the pistons and rings in from under neath the block or am i going to have to rip the heads off to get em in.also am i going to have to get oversize pistons and rings or can i just get standard rings and give the block a light sand and still use the same pistons?can i also just get standard bearings as i dont want it costing me s**t having to get crank reground and all that jazz...info please..just want to get it in my Xd so i can have a driveable V8

Mate unfortunately to do rings the motors going to have to come out....
You will find its probably got a couple of burnt valves if its low on compression, and you might aswell put a 351 crank in there while your at it.

you cant do rings from the bottom, on any engine...
heads must come off and you can check the valves once the heads are off. Chances are the heads will need servicing and hardened valve seats installed.
