i have been toying with the idea of swaping in a 4bt into my blazer for awhile now. id like to keep the 700r4 but put in a stronger one. what do i need to complete the swap? what do i do for motor mounts? will i have to do a body lift? is there any shops in CA that can do the swap for me (don't have alot of free time)? will my 1/2 ton axles hold up?

all of your questions can EASILY be found by searching. the only thing that wont be is for a shop in california to do it. if you were close to me, i would charge about 4000 in labor. you provide ALL parts.

Also might want to ask around as to how your local DMV is handling "diesel conversions" for post 1975 CA vehicles. Policy seems to vary with differnt parts of the state.

How is your 700r4 holding up? Are you happy with it?

My newest one is sitting on the garage floor, still getting parts together for the build. Previous was in a dually diesel 4x4 and worked very well for about 30k then it got hit and parted out.

Definitely have to use a 700R4 set up for diesel, the governor plus about 5 major assemblies should get the post-86 upgrades if needed. Torque converter should be for low rpm/high torque as well. Also, the HD "K" case is almost twice as thick as other versions.

74 blazer 4b

I'm putting a 4b in a 74 blazer frame (69 truck cab) . Mine has the Dana 44 up front & the 12 bolt out back . I bought a 4" lift since I really don't like body lifts. I made my own motor mounts & everything is working out very well so far. I'll try & post some pics one of these days.

There are mounts that are bolt and some that will need to be made to fit .The 1/2 axles will work fine as long as you don't go above 35'' and keep it on the street,the gears could have 3:08 ,3:42 or 3:73 most were 3:08 that would be great for fuel milage.

Take some time and do you research ,find out what you have and what you want and then see how much Money you have !
