no class Posted June 30, 2017 Share Posted June 30, 2017 Is there a"B" stamped on the end face ? Quote Link to comment
Gixer1460 Posted July 1, 2017 Share Posted July 1, 2017 These casing marks aren't specific to models - usually only accurate measurement will reveal which is which. Looks like some bad wear on those journals so they could be scrap? Quote Link to comment
MeanBean49 Posted July 1, 2017 Share Posted July 1, 2017 As above, only way to find out properly is to measure the lobes and compare against standard specs Quote Link to comment
markfoggy Posted July 1, 2017 Share Posted July 1, 2017 Yeah sorry to point out, but SRad cams have nearly the same markings, but Wheels are on the ends natch. I worked my way through a cam mountain at Phase One a few years ago looking for hot cams, selection included K1/2/3/4 as well as the search for hot grinds. Was an epic, involving measuring and determining lift points. Quote Link to comment
canamant Posted July 25, 2017 Share Posted July 25, 2017 Making a camgraph is the only way to tell what you ahve got. I've got quite a few sets of cams and they are all different. Even a "soft" slabby cam is pretty good though. Quote Link to comment
Oilyspanner Posted July 25, 2017 Share Posted July 25, 2017 As above - + nothing really different between K and L cams - power difference was more restrictive silencers on the L, put a full system on either and they'll make the same power. Slabby cams are within a gnats todger too ! 1 Quote Link to comment
fatblokeonbandit Posted July 26, 2017 Share Posted July 26, 2017 (edited) The good ones have a B stamped on the very edge on the right Edited July 26, 2017 by fatblokeonbandit Quote Link to comment

Captain Chaos Posted July 26, 2017 Share Posted July 26, 2017 first they didn't work here but now they do Quote Link to comment
fatblokeonbandit Posted July 26, 2017 Share Posted July 26, 2017 i deleted them then re attatched them, Quote Link to comment
canamant Posted July 27, 2017 Share Posted July 27, 2017 I presume FBOB the numbers are the lobe height from the base circle. My experience is that the lift of standard 750 slabby cams is more than enough to get maximum flow through the valve and the duration is enough to get the engine running well well past its redline I'd be interested to see the camgraphs/plots for all of those cams jus to see what the differences really are. 2 Quote Link to comment
griff1400 Posted August 18, 2017 Author Share Posted August 18, 2017 Thanks everyone, i will have another look at them.. Quote Link to comment
