Are you happy with your ZZ430

I have a zz4 and thinking about upgrading to a zz430.
I already have the lt4 hot cam and 1.6 rockers all I need is the fast burns.
The final combo will look like this 1971 vette,ZZ430,Auto gear Muncy m22w and 355s
how does this look?

So,any of you all that have a zz430 are you satisfied with it?
What headers are you using with your zz430?
How is the low end power?

Will 1 5/8 headers work on a zz430

I don't have a ZZ430 from GM but what seems to be a clone. It has the fast burn heads but I am not sure about the cam. My impression--disappointed. If you want a powerful street engine I would go with a 383. The fast burn heads require a special header due the D-shaped exhaust ports. Several companies make these including sanderson, edelbrock, and hooker. Maybe mine just needs a better tune but overall I was expecting more!!!
