My fan shroud has definitely seen better days. Engine bays with the shroud removed have a cleaner look, not to mention all the extra room to work in. My question: Is the fan shroud an absolute necessity or is it more of a safety item (safeguard hands and long hair ). Thanks.

The shroud is an absolute necessity in a Corvette, particularly a big block. It's a critical piece of the cooling system. If it needs replaced, do so.

Thanks for the prompt reply, Gun. It's a smallblock soon to be modified, including a higher capacity radiator. Oh, well, one more thing for the wish list.

Since we are talking about fan shrouds I have a question. My needs replaced so I was looking this weekend at Ecklers and Dr. Rebuilds. Dr. Rebuilds book states to get the numbers from the orginal equipment if you are replacing it on a BB block. I would think a BB fan shroud on a 69 would all be the same what am I missing?

Everything else being equal, more power equals more heat the engine must shed, so an efficient cooling system is a must. It's good you're already planning on an increased efficiency radiator. Also make sure all the seals around the radiator are installed properly...they're an integral part of the cooling system as well. The radiator can only cool by having the outside air go through it...if the seals aren't in place, much of the air won't pass through the radiator, but escape around it. A properly fit shroud, fan and fan clutch help to draw the air through the radiator efficiently in sufficent amounts to cool the engine within tolerances.

I need to replace my shroud on a small block...anybody got a good supply source? Also will be needing a new Core Support...some rust at the bottom - acutually a lot...74vette

different big blocks had different radiators...

dewitts.com seems to be a good place.. everyone around here seems happy with them.. plus they have upgrade radiators, shrouds, etc..

as for radiator support.. ask dewitts.. but if not try dr rebuild..

you can find links to their site on my website.. under miscellaneous..

if you really want more room.. go with electric.. dewitts has a dual spal kit.. i installed one on a 49 chevy truck that was overheating alot.. its awesome

different big blocks had different radiators...

Thanks Ben
I may need to talk to DeWitts again because I have already ordered a replacement Radiator from him.
