I don't mind changing things out and going more custom or hot rod but only if there is no permanent damage. My ultimate desire has been to do a swap to a more fuel efficient motor with some good power but only if I could do it and still allow the car to be returned to stock. Keep it simple and enjoy it for what it is, you will enjoy that the most.Ĭlick to expand.The above information here is good to because it leads me in the direction to get answers to some questions I still had. I won't discuss your comment on not being a motor guy yet asking which complete motor swap is the best for fuel the end of the swap you will be a motor guy making it work! A stock style rebuild will involve the least amount of "motor guy" knowledge of all your options, provide the best resale value from an originality point of view and give you the best driveability without becoming a fuel injection/catalytic converter/lamda sensor expert. Start with a good stock rebuild (including the carb!) and go from there, everything else is a lot more expensive and will take far longer to achieve better results than fixing what you have.not to mention being relatively minor gains over stock economy. That Quad carb is easily the best fuel economy carb ever produced and doesn't hurt in the HP department either, find yourself someone good with tuning them and you can have your cake and eat it too. A buddy of mine had a 67 Firebird in HS with a 350 blue block and a four speed and he regularly seen 22-28mpg with it.easily the best fuel economy of all the muscle cars in my school.went pretty good too. Unless your willing to cut the car up and swap in the entire drivetrain from a donor late model it isn't going to happen without a ton of cash and heartache, stick with what you have and dial it in. 4-6spd transmissions with lockup converters and high ratio rear axle ratios are required.and a drag coefficient better than a brick doesn't hurt either.Īctually I'm willing to bet you can get better mileage with a well tuned Quadrajet than with a stoichometric measurement based fuel injection system, you can run a Quad much leaner than your fuel injection will let you. If you were thinking that putting a newer fuel injected engine into your old car hoping to get 30+mpg is going to happen.forget it, there is much more than the engine involved with getting good fuel economy. As for "wearing" the motor out.you can rebuild it more than once.how many miles a year where you planning on putting on it? Rebuild what you have and use a stock Rochester Quadrajet carb, it will get as good a mileage as anything else you stick in there. Oh, and since it is fuel injected, I would expect in the neighborhood of 30 - 35 MPG. You will be able to drop the Pontiac engine right back in in order to sell the car. They also have mount adapters.Īt the end of the day, what you want to hear is the following: Street and Performance will sell you a modified pan on an exchange basis. It sounds like you will be draping a battery cable from the left front of the engine bay to the right rear. You could put the battery in the trunk since this is going to be a hot rod. You could go to a Camaro restoration company, buy a 1st gen Camaro tray, and probably bolt it in with little or no mods. Not insurmountable, just something to consider. I felt that the fact that a numbers matching, 1st gen Firebird convertible was a highly desirable car IN ORIGINAL CONDITION was something you should consider.Īssuming you weren't interested in considering that (seems you aren't) I pointed out that the battery is on the wrong side for the Chevy. You asked if there were things you needed to consider. They have an ever growing aftermarket supply. I just don't want to "tune" carbs, remember, I am not a motor guy.Ĭlick to expand. If there is anything else I need to tell you to help you with your advice just ask.Īlso, are there any considerations I need to consider? Any other motors that would work? I prefer fuel injection but will consider any reliable setup. Lastly, I will have disc brakes all the way around. My setup will have new wiring harness' anyway and I would like to get a Classic Air setup for AC. So anyway, I am not a muscle head or motor guy so I need some advice. If I keep it the way it is I can either rebuild it later when I don't drive the car as much or sell the car and keep the original motor with the car. I figure it would be a shame to rebuild the original motor and then drive it a bunch and eventually wear it out. So I am leaning toward keeping my numbers matching Pontiac 350 on a stand and putting a fuel injected engine in the Firebird.
69 FIREBIRD DRIVER
I really want a quick but fuel efficient (as much as I can get anyway) daily driver car. Right now I am not in to car shows but I want a show quality car. Okay, so I have a numbers matching 1969 Firebird Convertible that I am restoring.
