the 6 cyl is much longer than a V8, so the fan was close to the rad, didn't need or have a shroud, not to mention that you could prolly take the fan off a 235 and still not have it overheat, they're real cold blooded
the reason that shroud is advertised as "for V8 only" is the vast majority of trucks were originally 235's [rad forward, no shroud] and most folks want to install a V8, but a shroud was NOT originally installed for a V8, moving the rad for the same close space was what made it work - so the shroud
is specifically for a V8 (installed in a 6 cyl truck), but if the fan is 3/4" with a good rad, good water pump, correct fan, and clean block, a good running 283 won't overheat
RAT - I don't remember the details, but there wasn't a spacer long enough to get the fan within an inch ... the mounting is the difference, the 283 had mounts from the front of the block to the front crossmember, if your 350 has side mounts, it was put 'where ever', compared to that, and looks slightly forward of where the factory V8 was, Andy's is back closer to the firewall ... don't have any pics after the shroud, but when I started detailing it looked
like this, note space firewall to valve cover compared to
yours, and compared to the
283 in the stock positionI see how you cut the shroud for the alternator, I didn't have to do that - I think you might be OK without the shroud except at extended idle in 100 degree weather
wilbur - I'm not sure if the aftermarket fan might make a difference in airflow, but you can definitely get a longer spacer to move it closer, and no matter what, I doubt you'll even get a shroud in there, let alone do any good with it, you'd have to cut it back to about where the white patch is in that pic - I'd be inclined to refund it before you cut on it, and figure out why the truck isn't cooling well enough .... turning it off as soon as you stop in those lineups can work too ... yes, most of the vendors offer pusher electric fans, but that'd have to be 'the' fan, otherwise it'd interfere with air flow for the engine fan
