![]() ![]() Oh does your shroud match the LMC drawing. Since I was looking for them up here.There not as much around here as they where, most are broken or changed some how. ![]() Please post up the year, make, and model of the vehicle you got it from as well as any other information that would matter as in trim level, with or without AC if it makes a difference, engine. Keep your engine running cool by replacing a. Some find electric engine cooling fans from later model vehicles. I think there is three SBC 73-80 shrouds. Reproduction of the original fan shroud designed for use with various 1981-91 Chevrolet and GMC truck models. Then I end up year ago putting Mercedes E Class electric PMW fan my rad a spare 454 shroud cut down and mounted fit nice.(looks like factory) Now getting back to shroud there is one shroud that if I remember right the top plate is molded in to the shroud hard to come bye. After getting the SB 81-87 upper rad supports it looks factory again and works. I look for a long time they were all was missing one part broken. So the top of the rad would have 1"to 1-1/2" gap between the rad & support (inclose) to finish off the top. The only thing I did not have the top plate to work the 77 shroud. heavy cooling the SB upper rad support higher shroud like the big Block. Im running a 350, not an LS but my mechanical fan works fine in Texas heat -but its because of the shroud - I would not recommend running the mechanical fan without a shroud. So I made up upper alloy rad support ran then for 2yr till one day I seen the big block that come with the old set up SB. I am not against a electric fan set up but if a mechanical works, why not. The upper brackets are lower in all most all times Reg cooling 81-87 mostly Rads come short but wider. You need small block and shroud to match you rad fan that your truck had.** or the RAD and fan top plate shroud you pick to fit.( has to work as a unit.) That why back in the early 2002 I keep the 77 454 shroud fan for the 84 rad support, but the 77 top plate would not be correct for the 84 support I got parts truck 6Cyl. I'm pretty sure there is two top plates they do not have, for sure that semi common but they do not have. Part it's the most common cooling set up. Now I know for sure that LMC does not sell all the top plate for the shroud. The one in the pic you said you have is mostly common for Big Block Extra cooling. "For the 73-80 rad support small block Reg cooling" I'm guessing. You need the Top plate mount that has bolting holes about 2" lower on the shroud side. So then this top plate not right for the shroud rad combo. Or when you bolt the top it does not hit the fan top or the sides correct. When you in stall the lower section in the correct location at the bottom in the clips not touching the fan bottom,or sides. ![]()
