I was on your same boat I've got a daily driven v6 and a classic project. For me that setup works great! But are you not interested in a classic mustang project? Im rebuilding a 302 and a 5 speed from an 83 mercury to put in a 69 coupe. And im hardly in over 3 grand.. Although my girl has a built '99 that's bad ass! So I can understand going that route.
'06 V6 Pony Package "Roxanne" - Mostly stock, only window tint and louvers with Borla pro xs muffler - Daily Driver
'69 Grande Project "Lola" - Currently has original 250 inline 6 and converted auto - have '83 5.0 302 with Holley 600 with a T5- Gonna rebuild, swap and enjoy
