Well, since mine is a '55 it doesn't qualify as a "hot rod" but I am reassessing my plans for it because of gas prices and fuel quality. This isn't going to set well with some of you but I have dusted off plans I had for a 355 SBC awhile back. It is basically a homegrown version of the 350 Ramjet crate motor but with a Q-Jet carb. It will run on 87 Octane, and a nearly identical engine got 25 MPG in a full size pickup with a 700R4 and 2.73's cruising 70 MPH on the interstate and dynoed 256 RWHP. My Stude will weigh in about 3100 with a SBC and 200-4R and is a whole lot more aerodynamic than that Chevy PU. With 3.73 gears and 28" rear tires I can cruise about 1900 RPM at 60 MPH, that's with tire diameter corrected to about 26.3" to compensate for weight. With that kind of RWHP it should run easy high 13's and with some strip oriented tuning low to mid 13's and I think I can still equal the MPG's of that PU. If I wanted to give up some ET bragging rights I could switch to 3.42's or 3.08's and drop my cruise RPM a little more. I don't see prices coming down, I think they'll just keep climbing and I believe the day is not far off where 87 Octane is the "good" stuff........... I intend to drive this car a LOT so I'm willing to give up being "different" for some fuel friendly performance. Yeah I could probably get the same mileage out of the Stude 289 and on 87 Octane but 256 RWHP too and on my budget? Not even close.
