What year?What is the correct ac Delco spark plug part number for a 350 TBI??
Asking because I just pulled out an AC Delco R43TS plugs, and every cross reference I find says that those aren't for my truck...
Are L31s computer controlled camshafts?
E-fan vs. auxiliary push fan ? There’s lots of love here for the dual electric fan modification. And lots of how to videos on the web explaining the swap. What I have not yet found (probably for my lack of research) is a solid explanation of why dual electric fans are a better solution than just adding an auxiliary push fan to supplement the stock clutch fan. Can you point me in the right direction to prove why primary e-fans are a better choice than a supplemental push fan? Appreciate your guidance.
There are some camshafts that you can run with the stock tune if that's what you're asking, but to really open up and get the maximum amount of power you'd need a tuned PCM. With a tuned computer you're open to a whole world of upgrades too.
I think what dictates a computer controlled cam is the amount of vacuum it pulls at idle? It could be TBIs that I'm thinking of.
I'm not entirely sure off the top of my head. I'm sure someone with better engine expertise and knowledge can step in.

I know the push fan in my truck only kicks on over 200 degrees, but with running a larger fan it keeps the coolant temps lower when the truck is running. I don't know about anyone else, but I think the push fan only works over a certain temp point. Unless you wired it to constant power with the key.
E-fans are pretty much the same principle as the push fan, just a whole lot more efficient at cooling and don't take near as much power as a clutch driven fan.
Personally I prefer my clutch fan/aux push fan;
