I have a 78 Blazer with a sb400/700r4/np203, 14boltff/dana44 currently. This week I'm getting a 4bt that is rebuilt and a nv4500 also rebuilt. 1) I have the original 203 in the '78. Can this be used with a doubler AND be put on an nv4500? Oh, it came on a kcase th350 originally in the truck. 27 spline count. 2a) the nv4500 will have a hydralic clutch setup in the bellhousing, what would be a good doner for the clutch pedal and master/slave cyl? 2b) On the brakes, what would be a good doner on the hydralic brake booster? Just any year in that era diesel 3/4 ton? 2c) Do I need to grab both 2a and 2b from the same truck? 3) the truck has a 2" lift and I'm going 4". Due to the weight of the 4bt, do I need 6" lift in the front and 4 in the back? I like the front either completely even with the back or up to 1 " higher. never lower. This is an "I experienced that" kinda question. 4) flywheel source for the 4bt to nv4500? 5) Motor mounts for 4bt? I weld good, just lack of time unless I have to. Need to order/junkyard the stuff above to get it in... 6) Dana 60 will be coming after the above changes - but that is a no-brainer. Thanks for the info, If you think of anything else, please feel free... Oh, and I have no problem making something fit. I'd just like to start out with the best/closest options.
