StephenBowen Posted November 4, 2018 Share Posted November 4, 2018 Hi Everyone. I have just bought a MK3 Spitfire project and am looking for a donor engine. The one I have is in bits with one piston missing. Any help or pointer would be really appreciated. Steve. Quote Link to comment Share on other sites More sharing options...
s99sdp Posted November 4, 2018 Share Posted November 4, 2018 I think I may have 2 here somewhere, you looking for a complete engine? Quote Link to comment Share on other sites More sharing options...
Marc HF Posted November 5, 2018 Share Posted November 5, 2018 Where are you. I have a complete engine here surplus to my needs. It turns but beyond that I would be reluctant to say much more, but it is ready to move on. I am in Essex if that is any use to you Marc Quote Link to comment Share on other sites More sharing options...
s99sdp Posted November 5, 2018 Share Posted November 5, 2018 Quoted from Marc HF- Where are you. I have a complete engine here surplus to my needs. It turns but beyond that I would be reluctant to say much more, but it is ready to move on. I am in Essex if that is any use to you Marc I'm in Northants, somewhere around here we have 2 engines. We've got 3 Mk3's in the family and we picked up the engines with donor car's along the rebuild process. I need to speak with my father and find out the condition of each of them but I think If you'r looking to strip them down then there shouldnt be any issues. Let me know what you're looking to do and I'll find out where they are and what he wants for them. Quote Link to comment Share on other sites More sharing options...
Matt306 Posted November 5, 2018 Share Posted November 5, 2018 Has anyone a Mk3 Cam for a Spit MkIV Quote Link to comment Share on other sites More sharing options...
RobPearce Posted November 6, 2018 Share Posted November 6, 2018 I have a Mk3 cam I'm not currently using but it's the Mk3 type that will need sleeve bearings in a Mk4 engine. Quote Link to comment Share on other sites More sharing options...
Matt306 Posted November 6, 2018 Share Posted November 6, 2018 sure I can pop some bearings in. i guess its a case of putting the mk3 shell bearings in Quote Link to comment Share on other sites More sharing options...
RobPearce Posted November 6, 2018 Share Posted November 6, 2018 I believe so. It's not a DIY job, though, I don't think. And it may prove more costly than a re-profiled later type cam, as sold by Canleys (and probably others). But you may feel a genuine Triumph camshaft is a better option.

Matt306 Posted November 6, 2018 Share Posted November 6, 2018 oh... let me research my manual Quote Link to comment Share on other sites More sharing options...
sparky_spit Posted November 7, 2018 Share Posted November 7, 2018 I think that the Mk4 camshaft has the same profile as the Mk3 one (25-65-25-65) up until FH25000 (in 1972) when it was de-tuned to a 18-58-18-58 one from the Toledo. So, depending upon what engine you already have, it may be a Mk3 profile cam already. Also, I think that if you do fit camshaft bearing shells into a "large cam" block, you can carefully knock them in using your old camshaft as a drift, but you'd need to have them line bored afterwards. Apologies if you know all this already... Quote Link to comment Share on other sites More sharing options...
Matt306 Posted November 7, 2018 Share Posted November 7, 2018 Its a 74 Spit, I am thinking i may just go for a Canleys one. Quote Link to comment Share on other sites More sharing options...
