I'm in the middle of dropping a 383 in my '74 right now 
You won't be sorry and I'd guess your torque will be in the low 400's.
While my '74 is smog exempt even in California, I would have gone this route anyway over the big block

If you don't mind, how much did your build cost?

Be aware that alloy heads and intake scream "modified" to any smog technician.
If you can get heads and intake with and "EO" number (Exemption Order I think? Edelbrock used to have these?) they should count a smog legal in most cases an should work. Also, be careful of too much compression, as this can affect other measurements (NOx I think?) during the test.
Good luck,
Tom

If the "alloy" intake has EGR and a choke plate it'll go through pretty easy - especially considering many carbed cars had them anyhow. (numerous L-82s, 80-81 Corvettes, and who knows what F-body LG4s and otherwise). I know the Edelbrock 3701 is listed as 50-state legal, though I can't say I've seen an EO for it. The ZZ4 (10185063) intake looks very similar to the factory aluminum intake and has all the emissions hookups.
If you're running A/C, pretty much none of the alloy heads are visible on a late 70's car anyhow. As said, though, paint will solve that.

If the parts have an EO# associated with them, the manufacturer can <usually> supply docs with the parts stating this. Then you should be good to go, without paint.
However, as pointed out above, most enthusiasts know more about what is "smog correct" than the guy testing, so you may STILL have an issue with such allowed/exempted parts.
