On a stock BP block, i have seen upwards of 300hp. On built blocks 300-400+ rwhp. But at 275-300hp... you're running with cars with 150+ more hp no problem.

I saw one of my friends 1.6 Miata take a C5 Vette pretty easily... and he was only at 236 rwhp. A Miata can handle the higher power, but can the driver?

The reason i think you dont see many Miatas runnign with the bigger cars is mostly because of the miata image. Any of you who are OG Moreland Ave peeps will know the name Humphrey (sp?)........
