chevy 250

Okay I Finally came to the conclusion that I'm going to put a 66' chevy 250 in my 54, because I already have one. If I want to put the 250 in with a turbo 350 how far off will the trans mount be? and is a short-shaft water pump going to make up for the radiator clearance? what else can I expect to encounter? I am going to order the stovebolt engine mount kit. I know this thread has kinda been covered but help any help would be very cool, Thanx, Nick

i dont know about the length i believe the 250 is longer, but you will need to rework the mount to at least make the center part drop out or you will have to pull the motor to get the tranny out for service.

 

but the cross member pretty much stays in the same location as far as foreward and back?

 

i took a 216 out of my pick up and put a 250 in its place, the 250 was about 3" longer and i had to build my own cross member and an adapter for the trans.

 

budd, your 250 didn't bolt up to the t350 w/out the adapter?

 

If he pulled a 216, he mated the 250 to an early tranny. 216, 235, 261 all had an early bolt pattern. 194, 215, 230, 250, 292 all use modern T350 pattern.

 

Short answer, you will need to modify/make a trans crossmember and likely move the radiator forward some, no big deal.

When I put in the t5, I welded a piece of angle iron to the rear of the trns x-member, and used a single bolt s10 trans mount. it should work the same for a th350 if it is the middle length one. depending on the tail shaft, it could be in the way or just right. Can't say without more info. Fortunately, the trans member is removeable, so you can get it all in place, measure and cut as necessary.

 

the 250 will bolt up to a t350, i installed a 3 speed standard, the trany mount adapter ended up being a 1" piece of angle iron with 4 holes drilled in it, but as i said i had the build a new motor mount/ cross member, th erad i moved forward about 3 inches, being a pickup you have more freedom to move things around.

 

Thanx for the input guys, I'm gonna run it. I'll deal with the rad clearance with a shorter pump and move it up a bit, build or buy the stovebolt engine mount kit and fab up/move the trans x- member as needed. Thanx bros-nick

 

I have a 250 in my 53 with a 200 4 R and yes i had to make my own trans mount but I 'm running the stock rad in the stock location with no probs as far as clearance. And I get 23 MPG and ran a 16.77 at the HAMB DRAGS

 

i guess it also depends on how close you get thet valve cover to the firewall

 

I got the same combinatuon in my 53/54 chevy made my own motor mounts and trans. cross member with square stock and round pipe very inexpensive to make I'll try to get some pics. and post them,it's not all that hard first time for me making this mounts.

 

yea man you should definately post some pics!
