I looked around and found the stock 元1 cam specs, which are: He's planning on getting the PCM reprogrammed. Something that will yield a noticable hp improvement without compromising drivability, it will still be his daily driver and will retain the stock tbi.
He wants it to have a healthy sounding idle, just a little lope opposed to the smooth stock idle. Nothing too crazy, I'll probably just unshroud the valves and do a little smoothing. He wants to do a little head porting and a cam upgrade while it's apart. We've got all of the accessories, brackets, and wiring out of the way, tomorrow the heads are coming off and going to the machine shop to get checked and surfaced if needed. I've got a friends '97 Silverado in my driveway with a blown head gasket, it's got the 元1 Vortec engine.
