Kev- whats the PCV valve look like and where it is hooked up to, that thing has got to be leaking somewhere. Don't give up on that 302 they are good motor and will be plenty for a S-trim or turbo, look at Tims car low 10's and it stays together and he has the stock computer still also, impressed me. I was looking at going 408 or 396 for my next motor but after talking to a lot of guys with power adders they all like the small cube motors, you don't need all those ci when you have a power adder. What about re-adjusting the valves and rockers, have you done that to see if that helps?
