    Heater, radio removal ?

    I'm trying to remove the radio, heater controls and the trim that surround them. Since the trim is 40 something years old I'm sure it is quite brittle. So I do not want to be prying on it too much so I do not break it. So my question is, how is all of this held in place on the dash? I need...

    Another front end conversion

    I have a 73 dart swinger and would like to convert to a 71 or 72 nose. Aside from the hood, fenders, grill, head lights, what else is required from the 71/ 72 years, what else am I going to need?

    340 hp capabilities?

    Looking to build a beefy 436" out of a 340 block. Was just curious what hp or around what ball park hp do these blocks split apart? I have a 71 factory production block. Would love to get a R3 block instead but I'll take what I can get.

    Bloomer stroker cranks ?

    I want to know if Rod Bloomer is still making stroker cranks. And if so does anyone know what he has available? I know the easiest way to find out is to call him, but I figured I would shoot a general question to the masses. Thanks

    4.125" stroker crank?

    Does anyone know if bloomer performance is still making these cranks? Also has anyone run these cranks and what were your results? I've heard of mixed reviews that these shouldn't be run in production blocks, but would be better fit for the x block or the r3 block.

    340 block or 360 block

    I have my hands on a 69 340 block that is bored .030 over and a 76 360 block bored .030. I plan to stroke one of them to use in my 73 dart. What are the pro's vs con's of each? My gut says to use the 340 block. Is there anything the 340 block has to to have done that the 360 block doesnt?
