Yes, I was starting to suspect I need to measure lift. It has no marking on the dizzy end so could be aftermarket as I too thought standard cams were stamped.
It has numerous idiotic repairs and mod to the inlet/ vacuum system too which is why they most likely have the ignition timing maxed advance and cam timing max on the Vernier too. Feel like Ive bought a car from a 90s max power reader haha. ________________________________ From: quantumowners@googlegroups.com <quantumowners@googlegroups.com> on behalf of Jim Hearne <j...@quantums.info> Sent: 27 April 2023 08:11 To: quantumowners@googlegroups.com <quantumowners@googlegroups.com> Subject: Re: [Quantum Owners] Cvh Valve timing/ cam query I’m not aware of a reason to use a vernier pulley on a standard cam on a CVH but people do funny things. I think all the Piper and Kent cams i’ve had have had the model number stamped in the dizzy end. I think the Ford cams do have a Ford logo and a part number cast into the cam. To be sure if it’s a standard cam you will have to start measure the lift etc If in doubt either put a standard pulley on it for the moment. Jim From: Mick L Sent: Wednesday, April 26, 2023 9:45 PM To: quantumowners@googlegroups.com Subject: [Quantum Owners] Cvh Valve timing/ cam query Does anybody know if people have advanced the cam timing on cvh engines in relatively standard form? Our engine is a 1600 bored out to 1800 and has a Vernier pulley fitted which is advanced full it seems. I thought it must have a uprated camshaft fitted. Upon inspection of under the rocker it had green dot valve springs which I thought were standard strength? Furthermore to add to the the mystery upon removing the dizzy there was no markings visible at all. So is it a standard cam fitted with a Vernier pulley? Or do standard ford cams have markings in the dizzy end anyway? I always thought aftermarket cams were stamped too so I'm a bit lost.
