EDIT: His catalog shows a C2 Direct Fit that he says will work and fit for both BB and SB cars..............so chances are the dimensions for BB and SB width are the same. But verify.

They aren't even close to the same. BB radiators are very wide.

The small block uses a 19" wide aluminum radiator, with no tanks. 427's (except L-88's) used a copper radiator with attached tanks, that was about 24" wide, though the core itself was about 19".
L-88's used a 21" wide aluminum radiator, without tanks. This was the same radiator as the second design 65 396 radiator.

The BB uses a 22.5" core and the tanks add about 4.5" depending on where you measure.

They did this because the correct way to talk radiators is never the overall size but instead the fin area of the core. The reason this is done is because when you recore a radiator the only thing you care about is the core size. The only exception (IMO) to this rule is the old plate aluminum radiators because they were all core and no tanks.

[QUOTE=Tom DeWitt;1597442618]The GM part book uses the term 19" and 21" for the 3155316 and 3007436 however the actual overall is 22.5" and 24.5" respectively.

Thank you Tom.

They are two completely different animals.
