I have a 65 Convertible, with a tired 289 and a C4 trans. I plan to rebuild a keep the C4, but I want to install a new 302 Crate Motor. I'm looking a the 4 Long Blocks that Mustangs Plus has in the catalog. For the money, I'd love to have the 345HP Aluminum Head model for $3195. My question is, why are the lower HP motos the same price or only $200 less for the 285HP motor. I want to be able to dive the car daily if I want to. It's not going to be a trailer car, by any means. And I really like the idea of having the horses on tap. I don't want to loose the drivability either. Help! Any suggestions would be great.
