what to do with my 273

I have a 273 in my 67 fastback and it's a great little motor.
I had the heads cleaned-up and put a solid .509 purple shaft cam 292 duration and new springs, the cam is a little big for this stock motor but, it really sounds nice.
it has low first gear 904 trans and 2500 converter ,391 suregrip 8 3/4 , headers,
flowmasters
I give the stock 5.0 Mustangs a run
if you just want somthing to cruise and have fun with and sounds good
