Hi I'm new to this forum, so im looking to beef up my chevy truck it's a 94 Chevy 350 tbi with 94k miles, i was going to ls swap it but its too much stuff to swap out, i want to keep it original, so i want to either mod the heads, but which would be a good set to go with? i also want to swap out my cam, which one would be best for that, its a DD but i want to make some power out of it, im already planning to swap out the gears to 3:73 gears, also going to rebuild the trans with a tci kit. i wanted to see what other ideas you all would have for this tbi 350 motor. I looked into the holley replacement tbi and also I'm adding an exhaust system I just have longtubes to the muffler I'm adding the pipes to the back, I have about a 3-4k budget I want to stick with the same motor, end goal would be at least 300-400 horsepower
