I have stock 92 350 TPI and one or more valve seals on my engine have decided to start leaking. I have come into a set of stock heads that I will be using to replace the ones currently on the engine. I figure that since I have the heads off, I could upgrade the cam while I am at it. The car is stock with the follwing done:

Ported Plenum, portmatched plenum, runners, and lower intake, AFPR, airfoil, low resistance wires (TPIS), timing @ 8*, Edlebrock headers (1 5/8), Flowmaster cat back exhaust.

If anyone can recommed a good cam that will work well with this set up and be under $200 I would appreciate it. It would be great if I could get 20hp to 30hp out of a cam change.

Thanks,
Eric

 

if you keep the factory hydrolic roller you won't find a cam under 200 that i know of. you could change to a regular hydrolic and lifters and change push rods.

The ZZ4 cam is under $200 from GM, but you'll need new valve springs to handle the lift, which makes it over $200 total. Most roller cams start at $225, but they're worth it. See the cam article in the tech section here for suggestions. Pick one in the 206-212 intake duration range, and under .480" lift if you're keeping the stock valve springs.

Thanks for the response guys. The $200 price was a number that I wasnt sure about but was just hoping to stay under. I can go over that but I am trying to avoid the Ligenfelter and TPIS price tags that I know comes with those cams.

 

The LT4 HOT Cam cost me $184 with shipping from www.gmpartsdirect.com. Our cars have almost the same mods done, and it seems to be a good fit for my car.
