Newby questions:

What's the most reliable power you can get out of a stock 302 shortblock? (I know that's subjective - making one full pass without the engine going kaput is reliable enough for some people).

What vehicles used the 302 roller block?

Thanks!

Since no one knows the answer to this question, could you at least point me to a forum that can answer the question?

A stock 302 block, properly machined and inspected for cracks and core shift, should be absolutely safe to 400 horsepower. Using a main stud girdle, you should be safe to 450 horsepower.

Many people have used the stock block for higher horsepower applications, sometimes much higher. But there is a real risk of main web failure above these levels. When they do fail, it is catastropic; usually the entire engine is lost.

Stock blocks are available new for around $325. Ford Racing Performance Products offers a 302 Sportsman block for about $875 that will handle 200-300 more horsepower. They also have a full racing block for about $1650 that will handle 1000+ horsepower.

The single biggest factor in block longevity is avoiding detonation.
