408 W2 combo - where to from here

I agree, the converter is definitely not doing the car any favours out of the hole, but if I get a bigger converter its probably going to create traction issues anyway because as someone mentioned it is a 11sec combo trapped in a 14 second chassis. I am really surprised it even got into an 11 with the current setup and gears as it is exactly how it came off the boat from California less the drum front brakes. Standard shocks, springs, torsion bars the lot.

I am shifting at well into the 6XXX rpm range in first and second, but according to the dyno it was peaking at 5500-5600rpm, it seems to still spin to 7000rpm especially in the lower gears and seems to hit harded in second when I take it out to say 6700 rather than shifting at 6000.

I do want to get the chassis setup for some drag racing but also want to make the power it should be making at the same time, just seems like the heads may be lacking enough flow for the 408 cubes as they are. If I put a decent converter in it without doing anything to the engine its going to have a very narrow power band.
