I've got less than 500 miles on my little 340 stroker and I decided to put nitrous on it. One thing led to another so I'm changing out my rpm air gap intake. Factory heads, the good ones, with mild porting. 1.5 rockers. Cam, I'll post the specs on it later as I don't have them in front of me. Holley 750 dp vacuum secondaries. The intake is port matched to the heads. Dyno sheet said I was making 498 hp and 530 tq. Good set up, I just wanted more power. I'll put pricing and pics on tomorrow.
