I'm currently in the process of building my 350x engine.
My mods will be as follows.
1.) 10.25 comp piston
2.) Megacycle 162-30 grind cam
3) port and polish by CT racing.
4) 5 angle valve job by CT racing.
5.) Hard faced rockers with stiffer valve springs and chromoly retainers.
6.)400ex carb
7.)uni filter with ported airbox lid.
8.) DG krome header with rebuilt supertrapp silencer.

My question is what kind of HP should expect from this build? My guess was around 40hp. Any input?

Stock motors push 27HP. So id expect 35-40HP from those mods at stock displacement.

you know… even if you ended up at 35 hp after your mods you'd still have a real butt hauler! and maybe you'll end up with more! good luck getting there man. much fun ahead for you!
