In the old days, slapping on Weber carburetors (yes I am that old), got big gains. The 370 is finely tuned and therefore not ready to throw out big gains as NA. SC or Turbo may get bigger gains but I personally am a little leery of punching an 11:1 compression ration engine. Need reliability. Daily Driver.

Like you through the years I've pissed enough money away on hotrodding that you could buy a garage full of new Z's and still have a bunch of mod money left over. Big blocks, small blocks, turbo's, twin turbo's, big nitrous systems, stroker motors, etc.
Money is a realitive thing and if your counting dollars per hp, it's probably not a hobby you should have. Just met someone while at the dream cruise in MI that did a twin turbo Z06. On 5 psi boost it made 651 rwhp. Completely redone from the O ringed forged bottem end to ported heads. Cost him in total $85K and the car was gone for a full year.
Trying to detox from big hp cars and N/A these cars really are a lot of fun. However, the hp bug is hard to shake and I just don't see much more in N/A gains. Eyeing forced induction and also leery of the 11 to 1 compression. The first trick is thicker head gaskets to lower the compression. After that it's a built forged bottom end.
What's the phrase......How fast do you want to go? Answer: How much money do you have.
