radiator w/electric fans upgrade questions

[EVRLET]

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.

Stock alternator is 105a and cannot keep up with two fans and the normal load. He will need to upgrade in some fashion.

thanks EVRLET. i've been doing more research looking at the fine print of budget setups and opinions of people on several other forums. the overall result of that is that a budget setup wouldnt be worth the risk of not being good enough. quite a few people on other forums use and recommend spal fans. i havent checked them out just yet. i am trying to keep this semi simple with a kit that has everything, rather than piecing something together.

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.

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.
