Brief history: 302 short block purchased and taken to machine shop. They bored it .060 over and said everything looks good ( this was in 2010). I ran the engine with probably about 200 miles on it and then it sat for years. Currently I have rebuilt the top end using the edelbrock estreet heads performer cam and intake. My concern is the integrity of the cylinder walls. I just drive the car to cruise-ins and Sunday drives. My question is am I safe with this block or should I quit throwing money into this block and look for another one.

Thanks.

If you don't experience any heating problems i'd just keep running it... There are thousands of 302 out there bored .060 ... .060 is still a standard offered piston for that reason... i have even seen some bored .090 and still running... kink of luck of the draw... as i have heard of going into the water jackets at .090 om some too ...

Ok awesome. I live in Arizona and when it had the stock radiator and iron heads it would run between 190-210. So I went with a 3 core and aluminum heads, hoping that will help. Thanks again for the reply.
