I dont know where it is,but theres a build somewhere about a 490 horse 318 that ran on pump gas an i dont think it was stroked either.
But dont quote me on the stroked thing yet.
Il try find it...
The comments made above by Guitar, SGBarracuda and Ramcharger still hold true even if they did get 490 hp running on pump gas. But it's sure not going to be nearly as street friendly as a 360 or stroker. Bigger cubes may not mean more top end hp (build dependant) but it sure does mean more torque and a smoother idle with the same cam. I bet that 490 hp 318 didn't have squat for torque under 4000 rpm. Strip only engine IMO. The only exception to the rule is if it was supercharged or turbo'd or running a nice shot of nitrous.
