This week I needed to remove the pilot bushing from my crank. I've always used the old method of filling the back of the crank as well as the pilot bushing with grease, then tapping in an old transmission input shaft. This forces the bushing out of the crank using hydraulics, the grease does the work for y...

Can anyone tell me what I'll need to fit a rad in my 65 when the 327 goes in. I've been thinking of all I'll need, but I'm kind of confused as to the spacer/shroud configuration. Below is 2 pictures of a 65. One (327) has the short spacer/rad/shroud, the other (283) has the wide spacer/rad/no shroud. How s...

I'm trying to pull the 327 Damper, but it will not budge one iota. It's deflecting the arms of the puller. Do I need to heat the damper to crank flange?

Guys, I took a head off my 327 today to see how much of a ring ridge I had. Turns out there is just a hint of it, in some spots I can't feel any. The engine had less than 50 thousand miles on it. So I'm not going with an overbore. My cheap 327 budget plan was to cut the ridge, and just simply replace the piston with n...

Dumb question. How is the oil cap removed from the valve cover? This one won't come out no how. There must be something simple I'm missing. I had to funnel oil in through the valve cover breather hole. Also, how was the valve cover breather fed? Did it have a tube running over to the air filter housing from...

Another project for our long winter. I bought this core about two years ago, to possibly add an overdrive to the 67. I love the BB, but with the 3.55 gear, she's not a happy highway cruiser. Turns 2700 at 60. I'd like to go further afield at some point, maybe check out some different shows. A overdrive is a m...

I have a broken bolt head for my flywheel inspection plate. The inspection plate sits up nicely and tight except the one corner (top drivers) but so far has not caused any issues however I know its broke and it bugs me. The bolt is broke off flush with the surface and I have thought about drilling it and g...

I'm interested in doing a heavy duty overdrive. Will a 4L80E fit in the Tunnel of a 65-70 B Body? It's a very big transmission, and the tunnel seems pretty small.

I just changed the thermostat & gasket on my 67 Parisienne and it leaks from the thermostat housing when engine runs. I just tightened it to what I think is the safest I should. Any opinions for solutions?

Before I put the car away in storage last year I started having a weird problem with the headlights on the car. I would turn on the headlight switch and the headlights would not come on. However, if I pull the headlight switch to the "on" position and then push the floor mounted high beam headlight swit...

The carburetor on my 65 Acadian Beaumont SD with a 230 6c has a hesitation and the last mechanic to look at it said it was hard to replace or repair. Any suggestions would be appreciated.

Need to replace drivers side engine mount. Engine is a small block. Does the power steering bracket go against the block? Or does it go on the engine mount? I would think on the engine mount As it is now power steering bracket touches the block first... and to me it looks wrong

I am just researching electric fan possibilities on a big block. My 396 runs nice and cool (185) on the highway but slowing down in traffic, the temp gauge will climb up to 200.

Wondering if someone could help me out, someone that has a yoke laying around, or is in the process of doing a diff.
