At 9 psi on a low compression 418 your turbos will be moving more air then with the 376 to get to that same 9psi so I personally feel you would make more power. Are you doing heads also? That would make a big difference too.

Hi Cyber...(another great guy on here) thanks for chiming in. Yeah man i agree...its so iffy, but my engine guy is just gloomy. I know the turbo are gonna have to press more air, and I dont mind. i figure we can increase timing overall too. Since I have less chance of detonation, and I am running forged all the way. Well the head has dual vs, manley push rods, i also got new lifters and I did a trunion comps upgrade to the stock rockers. I did not have no polish or port work done. i figure that the nnoey is better spent else where at this point. Maybe down the line I might get some black label or arf heads. the cam is a turbo spec cam. I think with the extra cubes I will have a lil less lope and a bit more torque lower in the the rpm range.
