79 Chevy K10 4BT Conversion
I am in the middle of a 79 Chevy K20 SWB "restoration". I bought it running with a 400 sbc, th350, and np203. I wanted to install 6 cyl. cummins but was scared away by the weight and size. I know it has been done. I changed everything after reading this and other forums about the 4bt.
I rebuilt the 400 and even bought a 700r4 and np205. Every thing was in the chassis and even had the exhaust run. Once i made up my mind I yanked the motor and put it in another truck.
My current plans are to run a 4BT, SM465, np205, and a gearvendors over/underdrive
I plan for this to be a daily drive that will some bassboat and jeep towing.
I plan on running 3.73's and 33's to start and maybe go up to 35's to get the highway rpms closer to 1800 rpm (i gather this is the sweet spot). I have a few pics but do not have a motor yet.
Tranny Gear 0.78
rpm 2000
gear 3.73
tire size 34.5
mph 70.55561971
What do you guys think?
