what do to with a 400sbc

so some of you may know i have a complete 1973 400 sbc and it is completely apart now i want to rebuild it myself with the help of my dad and his vast experience and i need suggestions as to what i might want and what to look out for etc....

the crank needs to be turned and i need new pistons.
and im basically working off of a low budget

since i dont need to bore the block i will be getting a set of standard bore 400 pistons (8.5:1)

now my dad was suggesting a simple rv cam, 425 lift (how will this work out with 273's gear ratio)

i will be buying a set of hooker headers 1 5/8 etc.. (any of company i may want to look into)

for the intake i want a dual plane ( performer, air gap) *about the air gap is it compatible with a a/c p/s (my el camino has all the options)

and finally for the carb i have the stock q-jet that came off the car and it was rebuilt professionally and it works great but i could probably get my dads 600 holley vaccum secondary)

and the heads are 194, 150's so they flow plenty for my liking and we will be porting them and such

with all these mods i ran it through desktop dyno and i am getting a 330hp@5000 and 392ft lb's@4000 (with a motor like that in an 5th gen el camino somewhere between 3600-4000lbs, what kind of 1/4 am i looking at)

thanks for all the help
