I have a holley 450 mech sec. and a holley 600 (which I got and was told it was a 465 but nope and didnt get my money back )and take the jets and bowls from the 450 and put it in the 600 and make it work just untill my carb gets back from sterling?

 

Take it apart and see if they fit? I wouldnt know, is it a 450 or 465? I know RB sells the 465? I would think if it lines up it will work? What is wrong with the 450? I would use that.

 

the 450 just wont tune right it bogs and carrys on tried everything just going to let her sit till sterlings done
