The problem with going to bare metal with strippers or blaster is that every dent or ding is now exposed and you or the body man will spend hours $$$$$ applying bondo or filler to flatten every little exposed ding. You should sand off some of the paint to see if there are any rust areas but if...

Have a vibration issue with my 71 tang. The 40 year old trans mount had collapsed the rubber so that the metal part of the trans mount was resting on the metal cross brace. Every vibration in the drive train went right thru the body and shook the whole car. A new trans mount eliminated most of...

Older Fuel pumps can be a bear to attach and remove when the pump arm has pressure from the eccentric. The trick is to place the eccentric in a position where there is no pressure on the pump arm before installing or removing. 302,351C and 3451W: place the #6 cylinder at TDC (cylinder second...

I disagree with using solid lifters or weak springs to check rocker arm to valve tip relationship. Hydraulic cams run with the lifters under a 'preload' from the PR. That is the stock geometry set up. Solid lifters change that preload set up and are only good for testing mechanical cams. Weak...

I beleive it is best to use an iron gear with FT cam and steel with a roller cam. Bronze is a softer material which is often used with roller cams but needs to be replaced often since the hard cam gear wears out the bronze dist gear but prevents destruction of the cam gear. Easier to replace a...

The stock single point dizzy distributor was a hassle for me cuz it wasn't easily adjustable. Had to send to someone with a distributor machine to get it recurved. I went with a dual point Mallory vacuum advance dist which is totally adjustable DIY at home in the garage. Simple, inexpensive, no...

So, ask the shop about the last 3 points and keep you "foot out of it" for a little while longer. I do not understand the reasoning for easy driving a new motor for 1500+ miles. This used to be a common beleif. I have become more skeptical after watching TV auto repair shows where they take a...

Sounds like you are sucking oil into the cylinders. plugs will tell which cylinders are sucking oil. Could be a bad intake manifold gasket seal so that the intake port sucks oil from under the intake past the gasket and into the cylinder. Also check the valve seals to see if they are in position...

1971 mach-1 351C rebuilt C6 When I put the C6 into gear there is a very loud metallic clunk/bang noise and jerk in the drivetrain which is very irritating and does not sound or feel normal.The drivetrain engages with a very loud clunk. What could be the problem.

I have a Ford #91 TC from a C6 which is a 12 in. and the number 91 is stamped on the body of the TC. What are the specs for this TC such as original engine size match and the stall speed. My Factor shop manual only lists info for TC number from 57-62

Had the same problem when I rebuilt my 71 351C. Donut gaskets looked like a great idea but did not fit the pipes. I don't think the 351C needs a gasket on the exhaust manifolds. Just for the fun of it I tried to make the gasket work. I had to split the gasket in half like slicing bread with a...

1971 factory shop manual - best 20 bucks you can spend

Internal balance allows you to replace the flywheel and balancer(neutral balance) anytime without the need to rebalance the engine. Also precludes the need to deliver the flywheel and balancer to the engine builder when the engine is being assembled.

had a similar problem with my 71 column. I used nylon ties(or rope) attached to the under side of the dash to create a cradle under the column to hold up the column so my hands were free to work and the column would not fall on the floor. also have to detach the column at the firewall to allow...

Lowered the front springs 1 in and installed new rear axle and rear springs and noticed a vibration above 45 mph which increased with car speed. Vibration was from the rear and went through the back of my seat. Bought an magnetic angle finder from harbor freight and with full weight on the...

I have a C6 tranny in a 71 mach-1 and would like to change the shift point rpm. Specifically to raise the rpm shift point between gears. How do I do that. ?

I did this on my 71 and discovered the geometry of the fans are different. The fan clutch was positioned closer to the motor. Apparently, to move as much air as possible it is best to have the fan closer to the rad. I ordered a spacer from summitt racing . They have a huge selection of different...

Over the years I have had service shops sabatoge my car. The plan is that you will come back to the shop with a new problem and they can charge you again to fix the new problem they created . Here is a few of the tricks . I am sure there are others. 1. unscrew a spark plug to the last thread ...
