I thought the only diff between the blacktop and silver top was the different wieght in internals?

how are the heads different? i thought that the only difference is the throttle bodies. silvertop throttle bodies are only a few mm smaller? they are both vvt... according to wiki.

well i have a silvertop anyway.

blktop combustion chamber on left, silvertop on right....


thank you bill

A blacktop engine may be an interference engine unlike all other A series engines, this will be tested soon

did this ever get tested?
