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..

Nice.

mmmmmm, big block

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):lol:

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..:metal:

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?

Re: 70 2wd blazer going back together
 

i did not drill holes..the rear 2 top holes and the rear lower 2 holes..the 67-71 big block mounts bolt right up..

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.

I wish i could have it done now..but I have plenty of other cars and trucks to work on ...I have to pay bills...1st...:waah:
