Hi there,

Thanks,
John

Dear Johnnymack_mk1.

First camshaft is a streetable camshaft which requires no very special work on the head and pistons. let's say for 90-100 BHP.

Second camshaft is only for racing, will power up from 5000 Rpm till 9000~9500 rpm. (below 5000 Rpm no power!) Needs a lot of work to the head and pistons, inlet valve is open at TDC already 5,2 mm instead of 1,9 mm.
On 1,4 liter 135~145 BHP with good fuel system, weber 45 or Throttle bodies with fuel injection.

Fuel use is huge, 1 liter on 5 or 6 km.

Hope you have something on this answer.

Best regards,
Michael Nooij

I have book 69!
