I'm new to this, I'm not sure if this is a rediculous question or if I posted in correct thread, I recently purchased a 99 z28, the motor only have 9,300 miles on it, it was pulled from a wrecked vette. It has lunati gold springs, lunati chromoly push rods, comp cam 224/230 .581 .592 114lsa, ls6 intake, cnc machined tb, areomotive fuel rails, aeromotive 340 pump, and boost referenced regulator, 1 7/8 stainless headers, ory with cut out, lid, HP Tuners Pro, promotions built t6 with cfdf clutch, billet still fly wheel, there's a lot more that I'm forgettimg' my question is what kind of rwhp should this set up make and what are there any small things I can do to gain HP? Thanks in advance.

 

The hp will depend on the dyno, but maybe around 390 rwhp or so. Little things you could do to boost the power a bit are a ported TB, ram air mod, underdrive pulley, and probably a couple more i'm forgetting. Also running the right fluids, having the correct compression, etc...will all add up here and there

 

The tb is ported, it seems to be tuned very well, I'd like to get a little more bottom end, from 4k up is nasty.. I don't even think the motor is broke in yet , the stock cam looked brand new no score marks or wear whatsoever,the exhaust runners didn't even have soot. What is the ram air mod?? Mobile 1 synthetic only in it, it also has a beefed up 10bolt with 3.42s

 

Here is the ram air mod which is free to do basically, or you could by a ram air kit like a SSRA or Chris1313 and gain a little more
