Engine rebuild advice
 

Hi there I'm a newbie and have a 66 122s with broken rings in two cylinders which will probably mean I need a rebore as there is some scoring to the bores. The engine has twin SU's and a four branch exhaust. Would there be any gain in HP by putting a D camshaft in while I have it apart or would I have to do a load of head work as well.
Thank for any advice
Mick

Hi ya ,

Yes a D cam would also work well with the twin SU’s so very worth while indeed
Will work nice 👍 go for it I would for sure

All the best
