4AGE block differences: smallport redtop Vs silvertop

[Mr Revhead]

you are probably talking about the early gze ones.... remember there was more than one type.... the ones shared with the silvertop are skinny compared to the earlt one, but they are still quite strong. the blacktops are skinner still and no good for high stress

Hmm, got me curious now I'll pull apart the wrecked 20v in my garage on the weekend.
