Shift in 1st and takes off like a rocket! Now if I let off the clutch just a little say half way goes fine like its supposed to. Should there be or should I install a stop for the clutch pedal? I need to drive this thing!! :D :D

Bill,

Glad to see you've made it this far ( now the fun really begins !!! ) don't rush things. If you looked things over real good prior to the reassembly ( did you have the trans seperated from the motor, and did you inspect the fly wheel and clutch for burn and wear ? ) how was the pressure plate ? If everything was new I'd say leave it. But what is the question. I had the go cart scare me with 3.55 rear gears in it. It too was unholy !! I was not expecting anything like that, and my 70 Vette couldn't do that on its best day as I remember ( probably why I sold it ) If you are truly worried about future problems, replace them now. Mine were fine so I left them in. Remember as everyone says, The stock Ford parts are designed to work on a 3200 lb Stang, this is a 2000lb rollerskate, parts will last a bit longer, especially the driveline. Ask yourself how often do you plan on replacing the rear set of tires ? now about the clutch ? see where I'm going....If you're gonna smoke the rears every chance you get, replace the clutch, safe bet. Let me know what you decide to do,
We are ready to mount the body, 3402 is all buffed out !!!! WOW is it awsome, will post soon,
congrats Bill, talk to you soon.

Best wishes,
Eric Fraser

Thanks for the reply guys. Here is the deal. The clutch assy is new, original flywheel. She shifts into reverse fine. But in 1st gear it bucks when I let the clutch out then takes off quick, about lost it to the sidewalk. I may try starting off in 2nd gear and see what happens, just that 1st gear scared the bejesus otta me. Is this normal because of the lighter frsme? Thanks-Bill

Bill,

Did you purchase an adjustable clutch quadrant/ cable set up ? if so, try an adjustment first, it may need to engage sooner.. sounds to me like it dosent want to " bite " or engage 1st untill the cluch is all the way out, no feather action. Hope that is all it is. Also, just for giggles, check your trans fluid type and level, easy mistake, easy fix.

Latter
Eric.

Bill,
Are you sure it's the clutch and not the way FFR has you modify the gas pedal? The reason I ask this is because you used the word "buck". The gas pedal is super sensitive and it takes a little while to learn how to come out in first gear smoothly. I still mess up every now and then.

Just a thought.

Bill - I think from your description it sounds like you have what I call (I stole the phrase from I don't know whom) the herky-jerkys. Mine was from a very sensitive gas pedal/cable/cam combo. We installed Russ Thompson's gas pedal setup and it really made the beast much more driveable. Also (I know this sounds weird) the herky-jerkys seems more apt to happen when you use too little gas pedal and let up too quickly on the clutch. Try higher RPM and slower clutch release in 1st (also Russ's pedal assembly).

It's probably too late, but don't follow FFR's instructions and cut the mustang gas pedal. There is no need to do this. Simply trim about 1/2" off the bottom of the plastic pedal pad and it will not hit anything and you will still have the same throttle response as the Mustang. Cutting the pedal was required before the dropped footbox.

I dont think I cut my gas pedal at all.

Personally, I like the clutch pedal to be even with the brake pedal (at rest). I cut and bent my clutch pedal to align it with the brake pedal.

The Forte Clutch quadrant is an EXCELLENT addition to help you get your clutch adjustment under control.

One more thing..... a WEAK excelerator spring can cause you to be jerky taking off.

I drove a friends FFR with an extremely light accelerator spring. I damn near drove it up a light pole in the first 50 ft.

Well after leaking a bit of fluid from the tranny while driving it is shifting okay, got it up to second! Short street. I used ATF fluid and assuming this is correct right?
