bellhousing question

[rpoudrier]

If I run a universal gm bellhousing in my 79 by what kind of floor modifications will need to b done for the clutch linkage to work?

The geometry will be wrong. There are several bellhousings you can use while retaining the correct geometry, and I have documented them:

My car has had a regular style bellhousing for almost 20 years I've never had any issues other than I had to dent my floor for the clutch fork.

How big of a dent did u need to put in? Couple hits with a good size hammer do the trick

A couple hits with a hammer did mine.

Has anyone done the hydraulic set up from the f-body. I was told the plastic master cylinder does not build enough pressure to work with a performance clutch assembly. Any one who can verify this?

John Bzdel's done it. I have his clutch pedal, a McLeod F-body master (#139001, I think) & bolt-on release bearing for my M21. The problem with the stock F-body master isn't so much about pressure. It has a restrictor in the hydraulic line that makes fast shifting hard. The car's not on the road, but there's been enough conversions done the same way that I'm confident in it.

does the hydraulic set up use the same clutch pedal as the mechanical set up?

No, the hydraulic pedal is a custom piece offered by few suppliers; I know of 2. John Bzdel and another company that has one that looks very similar.
