If I mount a bolt-in style 24" radiator (p-side inlet, d-side outlet) in my '67, which fan shroud would I need? Lots of options and I'm not sure which one would work.

 

i checked here and 8146-5 seems to be the one?

i'm not sure since it's the wrong year, but its for 24" rad with LH outlet

The 24" smallblock radiator in a 67 will require 68-70 brackets, and 68-69 smallblock radiator and shroud. This has both inlet and outlet on the RH side. If you use the RH inlet, LH outlet, you will need to change to the 1970 water pump, 1970 radiator, and 1970 shroud. And 1970 timing pointer, because the the lower hose will hide the earlier style pointer. You'll have to mark the harmonic balancer, because the the original mark will be on the wrong side.

 

I'm looking at converting to a 24" aluminum radiator with a LH outlet and 2x1" cores (not one of the gimmick small-core 2 or 3 row units). It seems to me that the 24" radiator with the RH outlet wouldn't make really efficient use of all of the cooling tubes, plus I can't seem to find a good 24" aluminum radiator with RH outlet in the same $200 price range I'm looking at. I could just pick up a bolt-in 20" aluminum unit, but for the same price I don't see why I shouldn't upgrade to the wider unit. So that puts me back at the 24" bolt-in unit with RH inlet and LH outlet.

Brackets aren't an issue. I've got a friend who can help fab me up a set. I'm trying to stay away from the clamp-in brackets because a) it's a more expensive route, and b) a few people I've talked to who've done these conversions have had issues with them fitting aftermarket aluminum radiators.

I have a '70 style water pump on the way, but I'm concerned after comparing a factory replacement '67 WP to the '70 style at work yesterday. The '70 unit seems to be a bit taller and doesn't have a mounting boss for my lower alternator bracket. P/S and A/C are non-existent and therefore not a concern. But if I can't just bolt on my WP pulley and go, this project may start to get rather expensive. If I need to, I can link a couple hoses together with some tube and make my current RH inlet WP work, but I'd rather use the '70 WP if it won't be a huge hassle.

My concern with the '70 shroud is that it mounts at the top and bottom of the radiator. I assume it mounts to the clamps, which I'm not using, rather than bolting directly to the radiator. There doesn't seem to be enough material on the sides to mount it to the radiator side mounting flanges.

I have an aftermarket Powerforce balancer with three sets of timing marks, so I should be fine there. I'd just have to pick up a '70 timing pointer.

 

What about a big block style shroud?

 

i'd probably still go for this one:

Aha! Exactly what I needed. I couldn't seem to find that on the sites I was looking at. Thanks Kalli

 

Hope it fits :-)
