Well guys I have decided since ive got my hands on a 73 Caprice with a 400 im going to put it in my K10. Its only got 70,000 miles on the motor, so ill freshen it up with some goodies etc. Im going to use the tranny in my C10. Anyway, how much is going to be required to make this swap work. My tranny is junk so im going to get a new one anyway, TH400 problably. As far as everything else what will i need? Coil, Motor Mounts. Do I need to switch out fuel lines? Can I stay with my dual Saddle Tanks...Im kind of thinking about ditching one of them or both and using a fuel cell in the front of my box. Is there anything else Im missing? Im leaning towards tearing out all my wireing and setting it up like a racecar. I would like to keep the stock headlight switch and the things related to that if possible. As far as the motor goes. I would like to get it bored .30 over to clean up the cylinder walls. Its got a 2 barrel so I was thinking edelbrock intake and carb. Some kind of heads running to a flowmaster or glass pack. MSD coil probably. After the motor and tranny swap is done, Im going to install the 4 inch lift i got from stomper, and a DIY4X shackleflip and 35s I think, maybe 36s If you guys can think of anything im forgeting or helpful tips from those of you that have gone diesel to gas Id appreciate it. And no im not selling the turbo stuff off my GMC im going to keep it for my C10 which is going to get upgraded suspension and rear axle and going to be a tow rig.
