my first engine rebuild (318) advises

that cam looks good too.
thats little smaller than smallest voodoo cam.

i have seen a500 transmissions i a bodies with stock trans hump just some carefull hammer hits on right spots. crossmember needs to be remade as do transmission mount.
Thats not big deal, i have MIG and gas welder and lots of steel to modify those.
My duster has already 8 1/4 rear from dodge aspen, i welded new spring perches and shortened drive shaft with old russian made turning lathe :)
And it still holds, didnt even need any weigths :)
