Need some info PLEASE
 

I NEED TO GET THE PROPER FAN SHROUD I AM FIGHTING OVER HEATING ISSUES
SO I WANT TO START HERE FIRST
MY JIMMY HAD A BIG BLOCK IN IT ( IF MEMORY SERVES A BIG BLOCK IS LONGER THAN A SMALL BLOCK)
IT NOW HAS A 350 IN IT AND MY FAN HAD TO BE SPACED OUT APPROX 8 INCHES JUST TO GET IT IN THE SHROUD
MY NEW SHROUD MEASURES APPROX 4 1/2" DEEP
CAN SOMEBODY MEASURE THEIR SHROUD FOR A SMALL BLOCK AND LET ME KNOW
I WENT TO THE JUNKYARD YESTERDAY AND EVIDENTLY THAT PART IS IN HIGH DEMAND COULDNT FIND A SINGLE ONE
SO I AM WILLING TO ORDER A NEW ONE JUST WANT A DEEPER ONE
THANKS MUCH :gmc2:

Here's a couple pic's of my 70' Blazer fan shroud. 350 HD 4 core rad.

Dude that so perfect thank you !!!!!!
So you suppose that would be the depth
if i ordered a stock 350 4x4 shroud
because what you have would be exactly what i need

Re: Need some info PLEASE
 

That looks like the correct 4x4 fan shroud. If your jimmy is a 4x4, it never came stock with a big block.
If you order that shroud, you should be OK.

Yeah i know it wasnt a factory big block it was some sled 427 tall deck out of a school bus
thanx guys
i love this site

Re: Need some info PLEASE
 

4X4s have the longer shroud. Big block 2wd possibly the same?.

Re: Need some info PLEASE
 

someone is selling a fan in the trk section

Re: Need some info PLEASE
 

Big blocks are different than 4x4.

Re: Need some info PLEASE
 

got new shroud today
fan doesnt center to well in it
does anybody know what factory fan diameter is?
mine has a crappy flex fan
thanx

Re: Need some info PLEASE
 

Get Rid of that lousy flex fan! You need the correct GM heavy duty clutch fan unit. Not cheap, but if your radiator is in good shape, your overheating issues will be gone.
