That longer shroud reminded me of something... my 75 grand am had the same thing. Its got a pontiac 400 and its optioned on the "luxury" side, despite not being special engine or towing wise, 6.6l (6.5 litre as the rear lid says) was the base engine but i guess i never considered it maybe swapped....

I could walk up and measure it, but the wasps that live there are scary

Here's how the mod to the radiator shroud turned out. The edge that face the engine was run through a roller, so it's actually a nice rolled edge that folds back under about 3/8". The first photo was taken during a test fit. 2nd photo is of it installed, with engine running, in order to see how much of the fan is inside the shroud.

They all have to get shipped at some point. I bought my HD Hayden from summit...no issues.

So is that fan a reverse rotation fan? I’d love to upgrade to that fan for my suburban with a 6.2 in it. I don’t have heat issues but it would be good for the a/c in the summertime.
