Default 427 owners

hi, i posted this in another forum and couldnt get a response so i thought i would try here and see if i had better luck, i have a couple questions for you 427ish CI owners who DD theres if there are any, i have an oppurtunity to buy a 425 off of a local guy and i was debating whether or not to get it cause i would like to DD it if possible or is that just not going to happen? be honest,lol, what kind of gas mileage are u guys getting?(hoping for the best,lol) how big of a cam are u running or what could u get away withfor a cam? and there was another question i wanted to ask but i cant think of it right now. and remember im trying to make this my DD so im not trying to make a **** ton of power just alot with the best streetability possible, but if thats not really possible i guess i could just make it my weekend car and drive something else during the week. thanks

On the highway gas milage is outstanding. In town it is not outstanding lol. With a 244/250 cam, driveability is perfect. Better than the h/c cars I've ridden in. Not a daily driver, but it could be.

thats the thing i dont know anything about the motor, some guy had it built and had my mechanic put it in and do all the work and drove it for like 20 miles and totaled the car as in demolished it, but the whole drive train was fine, the only thing i know for sure is its a completely forged LQ9 motor that was bored to like a 425, i think it has a trex cam but not sure, and it has a LS2 intake which would come off, it comes with the wiring harness, pcm, and LT's, and all belt driven accesories, for $3800, but i dont know if im going to even get it now cause i found something else and i want something thats going to get better gas mileage then that and i want something i can daily drive so if anybody is interested in this motor let me know and i can get more specs on the motor cause my mechanic wants to get rid of it asap cause the guy hasnt paid for the labor done so my mechanic is parting out his car,lol
