70 2wd blazer going back together
I took it down for a motor swap..the 90 454 motor with TBI heads jusr sucked gas..4mpg..and it had to go..
I bought a 1990 454SS truck with a blown 350 in it for cheap..so i put the gas hog 454 in it,with a th400 and sold it.. Now its in with the 70 LS5 454 out of a chevelle..and a 5speed out of a 90 chevy truck..so it will be driven on the highway for those long trips.. |

Re: 70 2wd blazer going back together
got some more done today..driveshaft is in..I had one here the right length..45.5 inches..
I also used the 90 trans crossmember and had to drop the trans mount down 1/2 inch (due to being lowered to the ground) ![]() also had to cut out floor pan for large bolt on hump...but it was easy.. wont be long now..a few more hours and it will be alive again. I got the big block 67-71 mounts at knoxville pullapart for $8.00 lol it had a 460 ford motor shoved under the hood of a 71 truck..I found a driveshaft and moved that motor and got them out..best part i ever found there Nothing like a big block...then a LS5 with stock gm domed pistons. (std bore) .and a few mods to get 450 hp out of it.. ![]() |

Re: 70 2wd blazer going back together
Did you move the motor forward or to the big block mounts put it in the right place?

Re: 70 2wd blazer going back together
motor is set to the rear..big block mounts go in the rear lower holes..just as it would be in a truck.
I will be getting more pics soon...the NV3500 1990 5speed was a little big heights wise,has to go to large floor hump.. now i can run a fan shroud thats its in stock location. |

Re: 70 2wd blazer going back together
Did you drill holes into the cross member for the front lower mounting position or did you only use the rear holes?

I used small block 67-72 mounts with 2 small block crank bolt washers and they worked just fine. you can get the 67-71 big block rubber mounts but they are pricey. More pics over the weekend as i am about to fire it up and drive it out. clutch line and clutch master cyl. need to be made..and exhaust fixed..then its ready. |
