I'm rebuilding a 350 TBI to replace my 305 in my Camaro. What are good CHEAP modifications for this engine? If I was to spend under 100 dollars on performance, what should I put my money into? I have the t5 so I'm kinda flirting with disaster as far as torque goes. So in other words, whats a modification that I could use to gain power, at the expense of torque?

And since I have the engine apart, is there a sub $100 cam that I could put in that would work with the computer, and still give me a little more power?

And please don't say Vortec - the best mod for your v6 car is to put a v8 in it, best mod for a 305 is a 350, best mod for a 350 is a vortec, best mod for a vortec is a lsx engine, ITS GOTTA END SOMEWHERE!

 

Nothing you can do will help much with the crappy stock manifolds, Y-pipe and exhaust.

If your 350 TBI is a roller compatible engine the best cheap factory cam would be a F or Y LT1 cam or a L98 cam. If it is a flat tappet setup look at the Mellings MTC1 or Federal Mogul CS1014R. Its an old grind that will perk up the engine and still ECM friendly.

 

Further to Fast355 recommendations and if you are stuck with flat tappet block there is an improved version of MTC-1 aka CS-1014R, summit SUM-1102

CS-1014R (SUM-1102)
Chevy 262-400 cid Hydraulic camshaft, 1500-4000 RPM Range,278 intake/288 exhaust Adv Dur, Duration @.050 204 intake/214 exhaust, Valve lift 420 intake/443 exhaust, Lobe C/L 112.

CS-1105R
Chevy 262-400 cid Hydraulic camshaft, 1800-4400 RPM Range, 283 intake/286 exhaust Adv Dur, Duration @.050 209 intake/216 exhaust, Valve Lift .435intake/.455 exhaust. Lobe C/L 112.

Both of these cams have been used in TBI applications with decent results while running stock calibration (ASDU, etc). Just be aware that tuning is required to gain additional performance that is otherwise left untapped due to OE calibration. You'll need to install new lifters HT817 and upgrade your valve train - springs VS739R, retainers VSR7000R, and Locks VK115R. Springs and guides - OEs are probably tired.

Yeah, its a 93 suburban engine, so I believe that means flat tappet. I've got a 305 in my Camaro currently, which is a roller cam. Is it possible to take the roller components out of the 305 and put it into the 350?

 

'93 burban engine may have block which has provisions for a roller camshaft. Casting numbers may provide a hint, but to be certain you'll have to pull intake and inspect inner valley. If it is a roller block it will have 3 cast bosses which may or may not been drilled for spider plate retention bolts. If the bosses are there get spider plate and use it as template to drill and tap 3x 5/16-18 holes. Do not recall the hole depth but it should be on the order of 0.250 no more (measure depth in your 305). I can check on of my blocks in stand later. You'll need drill bit size F (0.257) and bottoming tap to tap these holes to get enough threads. Up in front of the block there should be mounting provisions for camshaft retention plate. GM used two different plate designs - sizes. If you're on a very tight budget you can re-use 305 roller lifters with you new camshaft. Same goes for retention plate which keeps camshaft from moving longitudinally in the block. Post photos of your 93 350 when you tear down into it.

My uncles 94 C1500 350 was a factory roller cam engine.
