Hey i just got a 1984 oldsmobile delta 88 with a 5.0 307 v8. I was wondering what are some cheap ways i can get more horsepower out of this car. I know its not a hot rod or anything but i want more power. Thanks alot.
First things first. Give it a tune up. New plugs, wires, oil, filters (including fuel). Some times advancing the spark timing can give you a few HP, but be carefull not to go too far and cause nocking. I would also suggest a set of headers and duel exhaust if you want to hop up the 307. Overall though you are right a 307 is not excactly a hot motor, it should not be too hard to drop a sbc in its place if you want to go that rout. Kind of a larger inital investment but parts would be cheaper in the long run.
My suggestion dude, and I know this an unsolicited tongue in cheek suggestion, but I'd pull the 307 engine and put a SBC in. They are cheap to hop up and a lot easier to find good deals on muscle parts used. Just kidding man!
a 350 olds or , shall I dare, a 455 will fit in there too? If my memory serves me corectly, all you'll need to do for the 455 is extend the belt lengths. I did a 307 to 350swap in a 81 olds wagon. Smooth swap.
a 350 or 403 olds would be an easy swap. you can find them in good running condition really cheap around here. don't know about the 350 but the 403 is pretty stout for a stock motor with low CR that can run on 87 octane all day long in 100 degree heat. i've never been impressed with the late 70s 350 olds.
