I'm talking real life rwhp numbers, not internet ones. This is a ported stocker 355 with an off the shelf cam we are talking about, going through a big stalled slushbox on ported stockers. Average ported stockers flow what, 265-275cfm or so? I've seen results from random local shop ported heads barely break 260cfm with the "Stage III" port job.
Then, there is the fact that stalled autos eat a TON of power on the dyno. Not to mention he would be lucky to reach 430rwhp with a t56 and the mods listed. Hoping for that in an auto would be crazy.
Not bashing any builds - I bet it will make a VERY fun street car and will run like a raped ape on the 150 shot, but there is no chance of 430 to the wheels NA with that combo. My prediction would be 360rwhp NA and right around 500 on the nitrous. In his defense "ported heads" is the most vague description ever, and if they are very well ported ~290cfm heads then he may put down better numbers, but still not 430.
I wish him the best though - none of these threads ever really end up with dyno numbers posted, but I would love to be proved wrong .

i wasnt trying to undermind you at all haha i was just honestly wondering why he wouldnt see those numbers. ive heard people getting 400+ from lloyd elliotts le2 stuff which is why i was confused, but it does make sense

He didn't say who did his heads though, which is VERY important.

Either need to build up your suspension and rearend alot.. or just buy a new rear-end.. be sure to post a video if you don't do either of my 2 options.. I want to see what happens! The car should SCOOT, figuring you have the right parts.. which you won't ignoring the rear
