my Low dollar 318 hop-up project

I got a magazine article where they dyno a dead stock 2bbl 318. But had to use headers cause of the dyno before they did there cam and intake upgrade and it made 186 hp. And made 282 hp @ 5000 with XE262H and 4bbl.
Probably puts the 318 100 hp under factory 340 hp numbers.
