Inliners International Forums General Discussion Hi Performance Help needed to change 4 piles into 1

In an effort to organize stuff I'm planning a new project. It will hopefully turn 4 piles of my "collection" into one good truck. Pile#1:complete '89 GMC 2500 305 donor pick-up,Pile #2:a good running stock 292,Pile#3 complete turbo set up from an '80 Pontiac 301,Pile#4 a '68 Chevy C 30 flatbed. The good truck will be the '68! The '89 will donate it's TBI,ECM,harness,700R4,fuel tank,fuel pump,tranny mount and cross member,EFI sensors. I plan to use a Megasquirt to regulate the EFI. I hope efi-dyi can tell me how to plug it into my harness. All three engines being nearly the same size305,301,292 it should be dooable,right? What cam would be best? What head work will help? I'll be hauling and pulling loads,it's a truck. I'm not new to 6's or this board but I've been on the information dirt road for seven years. Oh,right it's draw through. Why,because I have it.
