Critique my mismatched Teen Build.

Just put together a similar combo, stocky eddy heads on a 318. Rering on replacement pistons 10 thou below deck. Round about 9:1 comp. With a lunati voodoo 213/220 @.050
Has stock 2.92 diff and stock converter. Makes loads of low down torque and converter flashes up nicely. Idles with 14 " of vac. Those diffs can take a good bit of abuse before they break an axle. Lots of those diffs running 9's. Makes good power probs 320 hp should run a 13. Will be changing to 3.5 gears soon but leaving stock converter.
