    torsion bar and ps box upgrade

    you talking about poly bushings for the springs? http://www.summitracing.com/parts/rat-324k/overview/year/1975/make/plymouth/model/duster does this look right? i cat find any information about bearing sizes. only thing it says is that its for a 29 spline pinion. i know my axels are 27 spline...

    torsion bar and ps box upgrade

    okay i would have to use a different coupler for sure then. i actually had togrind the steering shaft end in order for me to drive the car to various places for me to work on it. that way it wouldnt wear completely through the headers. (im not sure on the brand). id say next friday i will likely...

    torsion bar and ps box upgrade

    i was looking at the box you offer and it looks great. i have a question regarding the coupler though. it looks the same as the stock coupler (dimensionally). and that is where my major problem is, my couple will just barely hit my header. so i need a coupler that is smaller in diameter than the...

    pulling heads

    im not saying it was prefessionally rebuilt, but it seems to have been done well. although they put a 727 flexplate in with the 904 transmission. i just dont like how i know nothing about the internals of the engine. there really is no reason for me to pull the heads other than to gain...

    pulling heads

    well i did not mention that the engine only has about 200 miles on it. i got the car with it bolted in to the engine mounts (no wiring hooked up at all). was told it was broke in at the shop it was rebuilt in out in idaho. so i would assume my compression numbers should be excellent, but thats...

    Mufflers Without a Drone

    i put borla xr1s on my duster, quiet at idle and light acceleration, and nice deep and loud on a heavy foot, no drone. they sound very tight, no hollow tin sound with them at all. i was actually hoping theyd be louder, but am satisfied. they are quite pricey i may say though.

    need 8 1/4 advice

    the strength of the rear end isnt my concern. i read plenty about them, and am fully convinced that it will hold up no problem with the 360 i am running. i just really would like to throw some steeper gears in the car to give life to the bottom end. so my question is, do i swap gears in the 8...
