L78 Nova Rad Help

[L78_Nova]

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.

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.

What is the correct Fan PN I should be looking for ?

[WILMASBOYL78]

The correct fan is the steel 5 blade unit...2 of the blades are offset...as mentioned it bolts directly to the water pump flange.

The only year for a clutch fan with BB was 1968...but, there was a short water pump that year.

I have a 4 core in our 70 BB TH400 L78 car...it's tight, but it works.

Your photos seem to show a wider space than I remember...but, I'll have to check to be sure.
