It'll work fine, and you can fine-tune it from there if you like.

I have been preaching this for years, and in fact did it myself.

I had changed the secondary rods & hanger when still 305. All I did for the 350 was rebuild the carb and reset everything to factory specs. It ran great.

(Although not as good as the current LS1...
