fan hitting shroud

[62ss409]

I had a shop transplant my 283 for a 350. When I picked up the truck they said they had trouble with the fan hitting the shroud and had to "adjust it". When I drove it home the fan hits the shroud on R turns. I checked the clearances and there is about an inch on the L (drivers) side, and an eighth on the R side. I will be taking it back to the shop on Tues. morning. The mounts look good but has anyone had a similar experience?
Thanks in advance,
Brett

Can the radiator be shifted side to side to even up the clearance?

It is up against the battery tray on the R side.

same issue here. fan hits shroud on right turns. maybe installing a battery hold down or modifying the battery tray will help. i look forward for some more insight on this too. i have a 350 in mine

I had a fan to shroud issue once before. It was with a small block with a long water pump. I just changed to a short water pump like these trucks came with originally. No more fan to shroud issue.

Are the motor mounts the original style? Is the trans in the original location?

Everything from the 283 went on the 350, including the powerglide and motor mounts. Are the mounts L and R? I measured and the block is sitting more towards the R inner fender than the L inner fender by 3/4". I know the answer is going to be simple when we finally correct it.

Make sure your rad support mounts are in good shape. My passenger side was collapsed and had to jack it up and re-weld it into the correct place. My shroud was not hitting, but my whole front was out of shape because of that.

Just a thought.

The motor mounts themselves are the same for L or R. The motor mount brackets between the frame and crossmember are L & R specific. When you say the engine is more towards the right by 3/4", is that the difference in the measurement on the left versus the right? Or is the left versus right measurement different by 1-1/2"? If this issue did not exist before the engine change, I would start looking at what was replaced or changed, one thing at a time.

unless someone had put a 292 perch in there at one time and used some hole stretchers

The truck was 100% factory with the 283. The mechanic phoned and asked if he could put a smaller blade on; I said "It's been fine for 47 years""Solve the problem; not the symptom" I told him to change the motor mounts first; the 283 was leaking and burning oil and maybe the rubber in the mounts had deteriorated. These mounts must have had problems from day one for GM to issue a hold down cable for the engine.(yes, that is still in place). We'll see what happens when the new mounts are installed.
