does anybody think that dual 2.5inch system would be to big for a 347?

No...

I like 3" myself.

...but 2.5" will do. Just be sure to use mandrel bent tailpipes. Muffler shops can't make mandrel bent pipes, they need to be ordered. Just take the pipes with you, and the shop will install them when they make the exhaust.

Good Luck!

On my 347 I used full lenfth headers 17/8 primarys with 3 inch collectors and then ran 2.5 inch h pipe from there back

2 inch would be to small
2 inch is 3.14 in area
2.5 inch is 4.90 in area
So obviously is flows alot better
