This is subjective. But look at 67 camaro LY6 carb conversion - E.T.'s inside
Very nice and fast setup!
I am going milder for my ly6 setup in my 68 nova.
770cfm VS carb (This is a little on the low side with I should have went with a 850 or 950 HP carb)
Get a Cam spec'd from Geoff @ EPS or Patrick G. and I am sure you will be happy.
This is an interesting article to give you the idea of difference in engine HP with cams and also difference between Carb and EFI.
What are your HP expectations? Using the stock ly6 cam went 12's in the 1/4 for 3pedals, your car is heavier so would be a bit slower.... But a car in the 13's is faster then you think. http://www.hotrod.com/techarticles/e...t/viewall.html
My cam is 222/234 @50 with .59X and .61X lift @ 111+4
I have the autokraft pan, it is very nice!
Headers, can't help you sorry
Cam, springs etc are best left to the pros
as said above contact Geoff @ EPS or Patrick G.
Good luck with your project!
