Tools similar to this one have long been used by professionals worldwide. The tool mentioned is an extremely high quality tool and functions as advertised. It's up to the individual to decide which tool to use. I'm proud to have one in my box and it feels good to use.
Hey Guys, I'm going to add more info to our website soon as there is a bit of confusion and misunderstanding on how these function. First, I designed these primarily to hold the cam pulleys in order to loosen and tighten the cam pulleys. In order for these to fit, the relationship of each cam pulleys to the other is specific and critical. Based on belt slack or tension, it may be required to rotate one cam very slightly with relation to the other to get the tool engaged. For a "lock and swap" of belts, please note the engine does not need to be at TDC. Orient the cam pulleys per the image below, install the tool to lock the cams, lock the crank, remove and replace belts. Note, because of cam timing, you may only be able to lock one bank at a time. The other option is to flip the main body and not engage the pins and just use the tool as a pure clamp. This will not resist torque on the bolts this way though. Using vise grips (while they may work) is less than ideal. For one, they may put teeth marks on your pulleys (if you care about that), second, they will pull the pulleys inward applying a load I prefer not to do and third, they won't resist the torque for tightening the pulley bolts. My project car had the bolts so tight that nothing would get them off without holding the pulleys from rotating. Feel free to contact me if you have other questions. Thank you To the folks that purchased these - I thank you for your support. When I start putting my motor back together, we will create a nice video on these.

Hi Mike, I don't know. Someone else emailed me an hour ago asking the same. I told him I would give a $50 discount to be a beta tester but he won't be doing a major for 3 years. So, what the hell, I'll give a free set to the first 348 owner that is ready to try them now and test. Email me for details.
Dave I will give you the correct answer so you will send me a set of those for free. The picture below shows that the 348 pulleys have fences on the opposing faces. They interfere with the locks, so no cannot do. Image Unavailable, Please Login
Two pieces of flat stock with a hole in each piece and a bolt and nut works ,and fits just about any dual cam head Sent from my iPhone using Tapatalk
Wish i could help , but i sold my ferrari , bought myself a frog face 911 twin turbo . No timing belt engine out 's required . Lol . I do want to take the time to say , i may have been hard on dave in the past , i changed my opinion when i looked at his very nice sticky work and the pictures of his meticulous engineering shop . The sticky work really does look first rate !
Thank for the reply anyway. I'd love to take you up on the offer but gonna have to wait until the fall to do belts. I'll ping you then if someone else hasn't already done the leg work. I'd be happy to work with you to develop a product that would work for the 348.
I would suggest that 348/Mondial T owner's check the WSM for their cars and see what the pitch is on the cam sprockets. The 355 is 11* 15', or 11 1/4 degrees. If the 348 sprockets are different than the 355 (they are a different part number) then they most likely the cam locks won't fit the 348. 308 and 328 engines are 12degrees so highly doubtful they would not fix those engines.
To add to what John has said, the other variable is cam-to-cam spacing. The 355 is 82mm. I've been told (have not confirmed) that the 360 has the same geometry and these should work on that model. I'll post in the 360 section...
Just a correction... 308 and 328 engines are 12degrees so highly doubtful they would fit those engines. I.E. WILL NOT FIT 3x8s.
