Stock appearing power

Want to keep the engine looking stock other than headers ,can i make 400 h.p. At the tire ..

It’s pointless to go for the factory look. The exhaust note of a sbf with 400whp is entirely different than 200whp, it’s not like you’ll be fooling anyone.

If you are looking to fool folks at a local grudge race, first pass you won't be fooling anyone anymore. Then you have spent tons to fool some people one time. What's the point!!
