30" set back too much?

[3 Squids]

Thanks for the input. This isn't for my center console. I am converting an IB/OB closed transom cuddy boat to OB so really it's my only option. I could spend $1300-$1600 on a 24" bracket which is the minimum I'd be able to go for cowl clearance or I can get this 30" one for $450. On a budget with this boat so if I could make it work just by moving some stuff around it'd be great. I'm redoing the floor and taking the tank out and most likely redoing the stringers and bulkheads so moving the tank forward would be a possibility.

The boat originally had a small block 350 in it so will the weight difference between that and my 200 help at all. I'm sure the 200 has to be lighter.
