Re: radiator w/electric fans upgrade questions
The fan assy. is from an '08 Chrysler Sebring with either a 2.7 or 3.5 V6. Cost me all of $35. You can get a new fan assy from Rockauto (TYC# 621570 or Four Seasons #76103). If you're handy with fabrication, it's easy to mount the fan assy to the radiator after you cut the mounting ears from the sides of the housing. I don't know what the amp draw is, but my 130 amp alternator doesn't seem to have a problem. The volt meter doesn't show much, if any voltage drop when the fans turn on, and they are very quiet, unlike the aftermarket fans. Also I don't have any heat related issues with the engine, even on the hottest days so far (temps have been in the 90's to 100+, unusually warm here in New England). I've also used a fan assy from a Ford Windstar for my last LS swap into a Squarebody. That worked well also, but the housing is larger, depthwise, than the Chrysler unit

Re: radiator w/electric fans upgrade questions
I have to disagree about higher amp alternator. I have a 150A and no issues. Dual 16” spal fans, 34” core aluminum radiator, pcm controlled dual speed. Fans push 2024 cfm each.
I will say from experience that these ebay and Amazon fan kits are subpar. Look at the cfm spec. Also the motors rarely last past 1-2 years. Don’t skimp on the wiring. Cheap is not the goal here for your cooling system or you’ll regret it.

considering that i may do a V8 swap in the future i still feel like i should at min upgrade to a larger rad now, so i wont have to later. so after research and great advise from you guys im leaning towards 2 options; up my budget to something like this cold case setup https://www.summitracing.com/parts/r...1500/year/1993 or a more budget friendly, less complicated upgrade would be a fair priced 34" aluminum rad and an og fan shroud, and stick with my clutch fan.

Re: radiator w/electric fans upgrade questions
for anyone following this, this is what I decided on was an all aluminum 2 row V8 rad I found on ebay for $135, and a V8 fan shroud to go with it. The only "issue" is that the fan is now like 6" away from the shroud. So naturally sitting at idle on a hot day the temp did get up to around 210 after about 15 min. Cruising around town at even 30-35 mph it's fine, and above 50 mph it runs even cooler that it did with the old rad. Last weekend the wife and I made an estimated 800 mile round trip to IN for the Hoosier GM truck rally with no overheating issues. Even though it is mostly fine the way it is I do plan on installing an extension on the fan shroud and a short spacer on the fan so that there aren't issues during the rare occasion of sitting in traffic.
