I have a newer 350 (forged in the 90') but I'm the first one to be using it. It's sitting at about 25k miles and I would love to change the cam in it to try to wake it up a little bit. I have a 65 4-door Impala hard top with the 2 speed powerglide that has 100k miles on it, just turned the other day. But the transmission is still strong and shifts hard so not worried about that. I have a Edelbrock intake and carb, carb is about 670 if I remember. Both went in new with the new engine about 4 years ago. It has Walker glasspaks on it, true duels with headers. So I would think a new cam could really shake things up under the hood. I'm not looking to try to come close to smoking my tires or anything like that. Just looking for something a little meaner then the stock cam. Also if anyone has any tricks other then putting in oxygen to the mix or something like it for getting flames to shoot a little farther let me know... I'm only at a foot and a half right now and would love to extend it just a bit. But my real question is about the Cam and what people thing I should try out. Really not looking to spend much more then $300 if I can help it, but want new. Thanks guys
