Default L78 Nova Rad Help

Installing a 68 Camaro BB 4 core rad into my 70 Nova. Bolts in OK but just want to check if it is supposed to be set back from the cradle this much ?? 3/8" gap from tank edges to cradle and only 1-3/4" between pump pulley and rad.

I can Squeek in a flex fan using a 1/2" spacer (required to clear the alternator and lower pulley) but it is TOIGHT LIKE A TOIGER ??
Am I missing something ?
Pics to follow..,

Thanks for any input Gary

The rad was original from an ss396 68 Camaro but may have been recored. It was missing the tabs for the lower shroud hooks. I fabbed some up to mount the shroud.

The gap between the radiator and core support looks a little wide, I'll take a pic of mine and post tomorrow night,originally a 396 nova had no spacer between fan and water pump pulley

I believe originally it would use a clutch fan ?? correct ??
I don't think a clutch fan would fit in the 1-3/4" gap.

Are the original Nova rads only 3-core?

Thanks for your help.
Gary

Big block Novas used a 3 core radiator. No clutch fan and no spacer. Stock fan was a 5 blade type, bolted directly to pump pulley. Even with a 3 core, it's close to the fan... A 4 core will work. Some guys do have 4 cores on there BB Novas.

3939001 is the PN!! The Parts Place Inc. carries a nice repop of this fan. Give them a call at 630-365-1800. Try a 1-800 first. Original fans if you can find one, go for big money. The repop fans will run you about $239.00.
