hey guys. I have a SBC 421 with 14:1 compression, I've ran a 250 h.p shot thru it a couple time without any problems. Like most guys I'd like to go a little faster, so I'm considering running a dual stage single plate which would give me a 150 shot out of the hole and then an additional 200 shot going down the track, for a total of 350 .
I know its a hard question to answer but given he fact that 400 Chevy small blocks dont have a lot of room between cylinders etc. I'm wondering if Im pushing the envelope too much, I hate to break it. Im at 10.40 with 259 shot and would like to get close to the 9's. I should also mention that The cam really isnt ground for big NOS applications. I'm very inexperianced with NOS at this point. Thanks for any comments
