318 2bbl manifold swap with OE cam - worth it?

Man, trying to get the whole linkage deal sorted out for this swap is making my head spin a little. Turns out the cost is not so 'minimal'. I know I know, never is. Always double your estimate and you will be in the ballpark. But I digress...

Looks like you need to get a 'correct' throttle bracket. I see AR Engr. makes an adjustable one which gets sold through the usual outlets. Link here. The nice thing about is that it's got a provision to use the Lokar cable kickdown. That solves two issues.

My question is this - do I need a new throttle cable as well. i.e. a longer one?

If all this happens, I'll likely be using a universal Holley 600 #80457 since they don't make the Mopar specific 80454 anymore. Also, do I need to get the Mopar throttle lever thing for this carb, part #20-7?

Thanks.
