Thanks Guys! I bought the car like this. I was pretty surprised when this came to light the other day. Although I'm NOT surprised that someone could overlook something like this when ditching the old 2 barrel setup for the performance upgrade of a 4 barrel and manifold. It's been like...

While searching for a new Holley carb and researching the transmission kick down, it has come to my attention that the one on my car has never been correct. Can someone tell me if I've figured this correctly? My car was originally a 2 barrel car. Holley says when switching to a 4 barrel you...

Should have included or been more clear: It was always my understanding that the vacuum modulator has to do with the shifting of the transmission. It was led to believe that would not be relevant when shifting from Park into Revers or Drive. Never moving. Sitting stationary. I didn't really...

I drive the car often. It shifts just fine. The whole issue still is, and always has been, shifting into gear and getting a loud clunk that jerks the whole car. I am just trying to figure out if the culprit is the rear end or the transmission. It seems as if the overwhelming opinion, when I...

So I put the car up on my lift, put it in neutral as suggested, and rotated the driveshaft. Watch the 2 videos. Doesn't seem like alot of rotation/play to me, but it has more of a "clunk" than the 2nd video. The 2nd video (aluminum driveshaft) is my 67. It has way more rotation/slop but a...

When I disconnected the driveshaft, I supported it up with mule tape so it would spin freely. I understand that this is not a great test of anything, but it did show me that the noise wasn't coming strictly from the transmission itself being put into gear. As I said it my original post, my 67...

so "72 Conv"... You say you had a shot differential that would produce such a pronounced loud clunk that can make a car jolt? That's what I want to know... No Detroit locker. Just an open 9 inch with 3.25's. I have a lift. I've been under the car with my hands on the rear end while my son...

Hello Everyone, I posted this same problem about a year ago but dads health caused me to step away from the car. I'm going to start over here... When I shift into gear, especially Reverse, the car has a loud clunk and a violent jerk. It feels like it wants to break something. What I've...

Just watched good video on fast idle adjustment by a Holley rep. Thought I'd share. can't wait to go apply this...

Thanks. I'll keep this in mind as I get back into this issue I'm trying to solve. I need to research the "fast idle" settings on the carb, something I am unfamiliar with. This could explain my RPM difference between the engine being cold or warmed up.. Thanks much

Wow...that's a very nice offer! However I am up in the east bay area. I went to Porsche Rennsport 7 at Laguna Seca so I've kinda gotten away from the Mach for a bit... I am about to research the "fast idle" settings. I'm not sure how this is supposed to work on this carb. Unfamiliar with ever...

Just signed in and saw last replies. Thnx all. I've had my '67 for 42 yrs. Many other stangs and Fords in our family over the years. Never heard a transmission engage like this one. When I got my 72, I later found out it had sat outside for over 10 years. I did a fluid change on the tranny...

All my literature shows 351C at 6BTDC. Why did you say 14-16 ? Thanks

Regarding the harsh clunk when shifting, at idle, into Reverse.. (and into Drive, but not as bad as reverse) Fluid level is good kick down is adjusted properly Vacuum modulator tests good U joints are new there is some slop in the differential, but my other Stang has more slop, and it doesn't...

Camshaft unknown. Mild, from sale info. To answer earlier posts, (mrgmhale), carb is 4160 series Holley. 7154 stamped. No electric choke. Hard to find info on 7154 number. ANYWAY, As I said yesterday on my 3:19 p.m. post, I believe I have a a transmission problem. I just realized I could post...

Precision Transmission...cracked me up! Seriously read that from a post from 7173mustangs from about 2013. Precision, assuming you are a transmission"guy", I have a question. Here's where I'm at..did 5 minutes ago. Warmed the car up. Lowered the idle to 600rpm. When I shift into Reverse, the...

OK Thank you everybody... so far! It's always hard on the initial post to include all the info. To much writing... Initial timing is at 6BTDC new u joints, ect. blah blah As a few said, I will look into fast idle issue. Not something I ever had to deal with. Idle is way not right! I've had a...

Hi everyone, This question is about idle speed...and tranny clunk. I rebuilt the Holley 4 barrel 8 years ago. It has always acted like this, so not a new issue. There is a major difference, 300-400 rpm, between idle in park and idle in gear. When the engine is cool, idling at 600, putting it...

Thank you much for all your comments...much appreciated! time to pull the carb and evaluate from the inside

My door panels were made by Dashes Direct. You mentioned plastic panels and door cards, so I wasn't sure if you have sports interior or not. The panels fit correct and the door cranks aren't too tight to the panel. Lot's of work though. Fitment of both door handles, stapling on weather strip...
