Hey,
Has anyboby sat these two side by side and seen the difference between a stock "70" 56 cube rude block and the SST-60 block ?
I have a chance to purchase an sst block mail order for $500.00 but I dont know if it is worth it since I already have a stock block . What was the rpm range of an sst60 ?
I noticed it takes the same part # base gskt so I am assuming the exhaust isnt hogged out .
