Please realize that this is just a SWAG, but I wouldn't be surprised if it made ~270bhp, or about 230whp. Pretty similar setup to mine, by the sounds of it.

11:1 compression

ported and polished

44 Mikunis

6-1 header with 2.5 mandrel exhaust

ZX electronic ignition

 

According to the (questionable) trap speed calculators mine makes 238whp, and it requires 95 octane to keep from pinging...

It's a car that we built in HS about 18 years ago. It's still in good shape with very low hours on it. A friend of mine bought it from another friend of mine. It is currently being restored and we were wondering about the output of the motor. I would have guessed about the same figures as you guessed.

 

Thanks for your SWAG!
