1973 340 Cam advice

Oh, I'll assume the Edelbrock Performer intake and 600cfm carb on the 318 in the Charger just now would be useless on a 340?
You can use the distributor, intake, etc... no problem because there the same for any small block engine. Of course the rate of which the distributor will advance will change for the application.
The 2bbl. will swap on. The Edelbrock Performer is equal to the stock 4bbl. intake. The Weiands are better. The 600 carb is fine.
