HELP - 302 in a Triumph TR6, clutch ques

I installed a 302 into a TR6 13yrs ago. I have used it as my daily driver until recently when I decided to change the C4 with a T5 (1990). I am sooooooo close to making it work. But I have run into problems with the clutch hydraulic system that I am trying to set up. It is not making the clutch fork travel for enough. I am trying to use an original 3/4" MC from the TR6 that only has 1" of travel. I am using a 7/8" slave but the combo only gives me 3/4" travel at the clutch fork....clearly not enough.

My question is, how much is enough travel at the clutch fork? If I know what I need I can properly size stuff, instead of guessing.

If anyone has experience a hydraulic setup...I will take any advice.

Thanks

Are the pictures I have taken during the trans swap....

I do appreciate the info on the different set ups that have worked for people. I think I am going to move forward on replacing the slave with a ¾” bore, instead of the 7/8”, that should give me additional .25” of travel. Hopefully that should get the clutch to disengage.

To answer some of your questions…. The 302 is very close to the same weight of the original straight 6, therefore the suspension seems to do a pretty good job. All we added was a rear sway bar to help the IRS. So far the original rear has held up to allot of abuse. I think the only thing that has saved it was that fact that it was automatic. The new T5 may make the rear be the next project. When we placed the engine, we move it way back, off the front wheel and as low as possible to help with the handling. The original TR6 had a shelf on the firewall behind the engine where the battery sat; we removed that and made the firewall straight. Fortunately, that was where the original heater box was inside the car, so I opted to install a small A/C unit instead. Being from FL, the A/C helped tremendously during rain storms. I have two 3 chamber flowmasters which produces a nice quite but deep rumble. The car is a blast to drive….hopefully I can get it back on the road soon.

I am still very interested in the different hydraulic set ups that have worked for people.

Thanks
