Keith Nock Posted April 25, 2021 Report Share Posted April 25, 2021 I fitted a jigsaw fast road cam and followers to my Gt6 over ten years ago and cant find the valve clearances for it can anyone help rest of the engine is pretty much standard along with original stromberg twin carb set up. does anyone know the clearances and which manufacturer would have made it. Thanks and regards Keith Link to comment Share on other sites More sharing options...
Mjit Posted April 26, 2021 Report Share Posted April 26, 2021 I've got a Jigsaw fast road cam in my Spitfire and the settings for that are 22 inlet/24 exhaust. Link to comment Share on other sites More sharing options...
Colin Lindsay Posted April 26, 2021 Report Share Posted April 26, 2021 Hi Keith; good to hear from you after all this time! Do you still have the same GT6? Link to comment Share on other sites More sharing options...

Do you still have the same GT6? +1 Good to hear from you Keith, sorry I can't help with the valve clearances. Kent Cams provide camshafts for some Triumph specialists, so may be worth contacting them to see if they ground cams for Jigsaw. Nigel Link to comment Share on other sites More sharing options...
Iain T Posted April 26, 2021 Report Share Posted April 26, 2021 Hi Keith, Jigsaw fitted this fast road cam for the PO in my Vitesse. It's an M27TR6PI from Bastuck, perhaps you can get the info from them or an Internet search. I've since replaced this cam so don't know the clearances and nothing in the Jigsaw file. Iain PS, I have this cam spare if you need another one! Link to comment Share on other sites More sharing options...
Iain T Posted April 26, 2021 Report Share Posted April 26, 2021 Just found the data sheet it says 10 thou for both inlet and exhaust. Seems a bit tight to me. Iain Link to comment Share on other sites More sharing options...
Mathew Posted April 26, 2021 Report Share Posted April 26, 2021 I must admit i don't know about fast cam's but as writing this the standard clearance would be normal? As iain has just beaten me to it! Link to comment Share on other sites More sharing options...
Iain T Posted April 26, 2021 Report Share Posted April 26, 2021 My higher lift Newman cam is 14 thou inlet and 16 thou exhaust. I think the Bastuck cam is the same or higher with more overlap. It really does depend on the profile. On this one occasion perhaps Jigsaw are right but most fast road cams have bigger clearances. I know this doesn't help!

Keith Nock Posted April 26, 2021 Author Report Share Posted April 26, 2021 Hi Folks yes it is the same GT6 I haven't used it very much in recent years Just insured and taxed it today with claasicline and will be going over to my storage garage tomorrow and take some photos of it for the agreed value insurance .It is still in the same condition when it won at stafford back in 2008 or possible fractionally better as I have had chance to finish some bits and have finally got the heater hoses to fit .Hope to put a few miles on it this year once I have gone through a few final checks Thanks for the guide to valve clearances will check my build records and see if I can find the set up info , It should be in their but I have so much paper work it is difficult to find one single sheet Regards Keith Link to comment Share on other sites More sharing options...
