I would like to know what cylinder heads you guys are using. Feel free to elaborate as you wish!

I would like a definite answer as to whether all ATF+4 transmission fluids are synthetic or not. While shopping for a quart today I noticed some bottles read full synthetic and some do not indicate. A worker at a chain auto parts store told me all were synthetic but I would like a second or...

I have a set of retainers and locks and I'm having trouble identifying whether I have a 7 or 10 degree products. Is there a way to measure without expensive machinist tools?

I would love to read input from you Moparites regarding what would be the ultimate choice for a street/strip camshaft for the most horsepower/torque with factory unmolested iron heads and still retain a very reasonable level of streetablity with a 440. I currently have installed a 284/484 Mopar...

I have just recently removed my 727 transmission for a rebuild and the factory style cooling lines are beat up badly. I want to replace them while the trans is out. I currently have an aftermarket trans cooler with the undesireable hose barb ends. I want to upgrade this entire transmission...

I am about to begin removal of the 727 torqueflite in my 69 roadrunner and I want to get some idea's on getting the car high enough to get this big transmission out. I don't have a lift and the last time I had the trans out I cut some 2 foot lengths of railroad cross ties and double stacked...

Help, I am experiencing a problem with my big block 727 trans. I cannot get first gear to engage at all. I have disconnected the shifter cable, ( Hurst Quarter Stick), and manually moved the shift arm all the way forward and I'm still only able to get 2nd gear. 2nd to 3rd gears are ok...
