Topside of Toyota. Again, compared to the Ford and the previous NA Toyota block posted by @ESP9935 it seems light duty oriented. I know appearances are not everything, but there's definitely a deliberate effort to reduce metal in this design. It may not be the issue at all, but it's worthy of...
Yes the absolute number claim here I can’t agree with, but there was definitely more margin in those days. A 1000 hp FI small block is going to have some problems keeping together with stock block and 4 bolts. 600-700 maybe yes I can agree with. But I agree with the essential sentiment. Bottom...
