I recently swapped out my stock 5 liter for a 350 long block (an L05). The has been running ok for the last 4000 miles on the stock EPROM, but I'm having a few little issues here and there. I'd like to swap out the chip before I rip into anything else.

Can someone recommend a good chip (manufacturer, burner, etc) for this set-up? I know little to nothing and my research within these boards thus far hasn't helped a whole-lot (too much info at once?!).

I can't get any cam specs (can you believe GM won't disclose this?! And I can't find it anywhere on the Net), but I'm unsure if this is needed to burn the chip. Here's the info on my setup -

350 TPI (brand new L05 block, originally used in caprices and the older impalas). Stock TPI intake.

All stock electronics from original 305.

T-5 manual tranny.

You guys rock!

http://www.fastchip.com/ is one source. They will get you in the ball park with your combinaion. I started with their chip and had a local chip guy fine tune it on a dyno for a few more ponies.

I think the cam in the L05 is something like 191/198 and .420 lift or so, but I am in no way sure of this.
