Mission Impossible 318

Just putting it in perspective, the stock teen is rated at 230hp @4400 peak. That equates to 274 ft lbs torque at that RPM.

If they use stock cam intake etc they won't get much more rpm out of it. I'll give them benefit of the doubt and say they turn 5400. Then they have to make 309 ft lbs at that RPM. That would be quite a dramatic increase with essentially zero real mods. I don't know how they'd get another 1000 rpm though. So if they still peak at 4400 then they have to be making 379 ft lbs at 4400 rpm. That ain't happening.
