I have a 68 Imperial, and I have the following mods made:
The 906 heads get the 2.18 and 1.81 valves, and a mild porting.
The cam is the 0.477 intake lift from Mopar Performance.
Compression increased a bit, by may be 0.4.
Stock (low rise) exhaust manifolds remain. I am not interested in over 5000 rpm. Dual exhaust with 2.25" pipes and turbo mufflers.
I hope to get about 15-20% over the stock HP rating (which is about 330-350 net ...). So, may be ... 400 hp at the flywheel?
Comments?
