I was wondering what kind of goodies I can get for the engine to get a little more power without breaking the bank. I am thinking of getting an electric fan. It's a 350 tbi with around 45k on engine and transmission. What else could help?

an electric fan will not give you a power increase, I do not know what you have done to you burb already but exhaust, carb, intake, If your trying to spend alittle more alum. heads are the way to go

or say screw it and buy a nitrous kit

Electric fan should yield ~10 HP
Vortec heads would gain around 40 HP
Edelbrock Performer intake w/ TBI adapter might gain you 10 or so HP
New bumpstick like a Performer Plus could get you 20-30 HP
Headers might net 10 HP
Hotter coil could do maybe 5 HP and crisper throttle response
Tune up the whole distributor, engine, maybe run a little lighter oil, maybe squeeze a fresh 100 HP out of your engine, you'd think it was a brand new one (practically would be too lol except rings/bearings).

What C4 is calling a bumpstick is slang for what is commonly referred to as a camshaft.

like the old saying goes speed cost money how fast can you go... lol c4 has got it pretty much down dont forget though you dont get far with modifying a tbi untill the cpu is holding you back so you will eventualy hafta get it tuned, i dont know about emissions in nd but id say a holley 4bbl would wake it up aswell you dont really need a 4500 dominator or anything a 4160 650 cfm would work great still get ok gas milage and be very krisp....... but thats just me im a fan of the carb (tune for fi~$500.... flathead screwdriver~$2)

hello im new to this site. but anyways i have a 77 k20 wit ha 350/350 and i upgraded to a dual cold air intake carb hat or a carb plenum. built mine for under 200 with 2 k and n filters, the more cold air the better she will run, and switch to the e-3 spark plugs, electric fans will free up some hp also like you were thinking.

How do you like those e3 plugs?

For anyone with TBI, the CFM-tech super sucker TB spacer, and a jet adjustable fuel regulator have a noticeable gain for under $150. Also, from the factory, TBI fuel pressures differed as much as 3 psi from the 13 psi that is advertised....just a regulator would be a good start, as well as nice clean fuel injectors, and an all AC Delco tune up.
