I have a '89 4wd Suburban and I just bought a SB400 block and I got the crank and pistons to make it a 406 but I think I wann keep it a 400. This is my first 4wd project and I'm not sure how to build it up; motor, tranny, transfer case, etc... The factory motor is 350, tranny is R700, and the transfer case is NP205. Any help would be much appreciated.
First off you have a 208 not a 205 2nd the 700 never last long behind any power or offroading 3rd did you buy this 400 used and is this the parts that come with the motor the pistons are the last thing you need to buy and are you going to keep the EFI
