AndyR1 Posted July 22, 2014 Share Posted July 22, 2014 Hi,The camshaft on my GE engine herald 13/60 is worn so im going to replace it with a spitfire mk3 profile one. I have been told that the spitfire profile large journal cam that canleys sell will not fit a GE 13/60 so is it possible to fit cam bearings into the block so I can run a standard mk3 spitfire cam?Cheers Andy Quote Link to comment Share on other sites More sharing options...
Dogsbody47uk Posted July 22, 2014 Share Posted July 22, 2014 Suggest you ask Canleys. They Know a lot! Cheers, Dave. Quote Link to comment Share on other sites More sharing options...
Dazman1360 Posted July 22, 2014 Share Posted July 22, 2014 Think you would need block to be line bored to fit bearings/camshaft, might be an expensive option.I replaced mine (also GE small crank) with one from Jigsaw Racing, talk to Mark he can recommend one for you.

Nick Jones Posted July 22, 2014 Share Posted July 22, 2014 It's easy on the 4 pot.The vast majority of them run without cam bearings with large journal camshafts. The only exceptions to this (AFAIK) are the Mk3 Spitfire and 1300TC FWD. These have bearing shells and small journal camshafts. However the block itself is bored exactly the same size as all the others.This means that if you want to run the Mk3 profile you can either:Fit the bearing shells (they just tap in to the standard block - no machining) and use a Mk3, small journal cam.Buy a cam with the Mk3 profile ground onto a big journal cam. Canley do them I think (certainly used to - I bought one once).Nick Quote Link to comment Share on other sites More sharing options...
