Nope.
The 235 is all cast iron. The 300 is also all cast iron except hypereutectic pistons. The 300 has a roller cam and .5 increased compression over the 235 (9.0 vs 8.5). The 390 is running the same cam as the 300 but upgraded Al heads and another .5 increase in compression over the 300 (9.5 vs 9.0). The 390 is also all cast (also hypereutectic pistons) but is blueprinted (vs the 235 and 300 NOT blueprinted).
235 - all cast
300 - Difference from the 235 - roller cam, hypereutectic pistons, increased compression by .5
390 - Difference from the 235 - roller cam (SAA), hypereutectic pistons, Al heads, blueprinted, increased compression by 1.0
Based on that, I assume the 235 and 300 will be essentially the same weight (all cast iron) and the 390 will be lighter by the difference in weight between cast and Al heads, so what 50-60#s?
