Re: mid 70 302?
The earlier is stronger but unless you plan on making over 550 to the tires i would use the roller block. The other block will require a retrofit cam or lifters to use a roller set up. This can get costly.

Re: mid 70 302?
Best solution on 302 roller based setups that will be making lots of power..........
After market block such as the Dart 8.2 Block................. I now have seen first hand what happens to the stock 5.0 roller blocks when used in high performance applications. They do not last if you make good power with them...... Note this is just MHO....YMMV.

Re: mid 70 302?
x2
To do it right you should really go Dart, R-302, or similar, but they take a big investment financially...trust me. The 289/302 engine from the factory was a "thin-walled casting" and included the 60's thru the 90's (except those made in Mexico). It kept the weight low. There are some minor differences, but they are all limited to aboout 550-600 at the wheels and even then, they're a time-bomb. For 400-450 rwhp, you'll only be wasting money on the retro-roller stuff...so keep the roller and put a 347 in it.
