Don't go with a 377. I can see how it's appealing as a high reving odd ball motor but a C2 like yours needs to shake the earth when it fires. If you can do a 496... do it.

106 is the center line, 110 is the separation. It's simular to what I'm running in the Cobra which is Cranes version of the E303. It also has a 106/110 but with only 220 @.050 and a .480 lift. With the Cobra the bottom end feels like a N/A car but when you get to 3000 and start making boost it just pulls hard.
To make it survive on 91 octane I have the initial timing set to 6 (not sure what total is because the tuner set it) and when I run race fuel I bump it to 14 and have another tune for it.
I figure that I will have the same results in the Chevelle. I should have around the same bottom end that I do now which is more then enough since I can break the tires loose at 60 on the freeway in third gear. It'll just be stronger from 3000 up with the blower.
