More power out of an 89 Custom Cruiser?

[RIMike]

I`m posting this for a guy I work with. He has a 1989 Oldsmobile Custom Cruiser Wagon with a 307 4bbl in it. He is looking for ways to get a little more power out of it for cheap. Also he wants to keep it emissions legal.

engine drop.....or well the obvious:

Do a COMPLETE TUNEUP FIRST.

That would include:

Delco Plugs
Delco Wires
Delco o2 sensor
air filter
fuel filter
PCV valve

Then for power:
Less Restricted intake system
2.5" Magnaflow HIGH FLOW cat (to keep it legal)
2.5" Magnaflow/Flowmaster muffler
Different Carb setup

This is a VERY HEAVY CAR. much heavier than the H bodies (3800'd cars)

you might ask for actual engine modifications over at http://www.oldsconnection.com since I know little about that engine.

Do what I said and it should be getting up a little faster.

Thanks for the info. The exhaust on these Olds has that wierd Y pipe where one manifold crosses over to the other before it gets to the cat. I would imagine there is a lot of power to be had be changing that set up.

no actually there would not be. I would do a FULL tuneup with O2,filters,plugs,wires,etc get a magnaflow cat on ebay for $50 or so and see how it is then.
