Piper Group A Rally Cam

[rsta1466 4]

Hello

 

i've recently got one of these cams and i have only just thought, do the pistons require machining to get this cam to fit?

 

i've done a search but couldnt find any information on this

 

Many Thanks

GpA/2 spec? If so no, but the head will need relieving.

My head was fine, no material at all removed, stick it in and see how it fits.

 

I had one in on standard valves for a while, but do check that the peak lift is not too much, iirc its marginal, sandy knows i believe, my cam was in sean mckeowns engine for a while that sandy revised.

Sure you're talking about the same cam Mei?

[welshpug 1,661]

Yup, says gp a piper / pts on the box!

 

Mine is gravel if it makes any difference?

Ahh, I just don't recall Sean having one. No idea, never heard of them called a 'gravel' cam! 300+deg & 4.8mm of lift??
