I was thinking free with some google ads at the worst, and cheap ass, as in c4+ carb+ home made engine mounts +r180 with provisions to swap the r200 later.
I wil be building a efi system based off mega squirt later. Right now i am talking the shortest way to a running car.
I picked up a working c4 for 50 dollars
I picked up a carb manifold for 60
I got the motor(89 351w out of a bronco) for a old f350 cab
carb is a holley 4160 from said f350
distributor from summit for 150
Sure its not perfect, but it will run and I am into the whole car for less than 1k, and I will be over the major hurdle of getting it in and running. Once there I can do coil overs, a manual valve bodied aod(4 speed) trans, a r200, a engine rebuild and a cv swap. Too many people seem to give up before that because they never get it running.
