307Cutlass87

Whats up guys, i have just recently inherited an 87 cutlass supreme that has 15000 original miles!! garage kept, i have done a fair amount of research on it but don't know a lot other that it has a sb 307 that puts out about 150hp, im wanting to start on a project car for fun i have a little money saved, i have read that this motor isn't a very popular motor for racing but i don't want to do a 455 swap, what all should i start off with to get this thing in the 200's, im wanting to have it running mid 14's if possible have around 2500 to spend for now, thanks,

this cars a step up from my turbo civic rice rocket,, anyone agree!!

Welcome to the site. I don't know if an 87 307 can run 14s. Someon on our site should be able to help you.

Put in a 350 Olds motor. Don't go too crazy building it, then diguise it to look like the old 307.

Yeah the 307 isn't really a beefy powerplant and if it's an 87 like you said, I'm thinking, unless there is a "9" in the VIN you're probably running about 140 HP and maybe putting down 100. The car will run 18's at best, maybe a peak at 17's on a chilly day.

Yes a 350 SBO is the way to go. Paint it black and put on an edlebrock upgrade kit. You're 200r4 tranny will bolt up to it just fine.

The Edelbrock kit is on Jegs and comes with the Manifold,Carb,Cam,Rods,and Lifters to get you up to 400 HP and 397 Ft Lbs with ease with 1 3/4 inch header dumps. However this kit is non-emissions complant. This will not work on a 307 either

The kit is $730 That's what I should have done to my Delta

well ALLOT of people are going to tell you swap to a 350 or 455.But hey you want to know what you can do with 307.hm i would start with the basic.. carberrator disabuter exhaust..go an check around an see what you can get for it.Don't think you will find allot but ill be going down the same path.Be 1 of the few who has a 307 with more the 180hp lol

what will it cost to do a 350 swap and where can i find one (junkyards, jegs, summit, etc..), i didn't want to get into a swap but if thats my only choice i guess ill go with it, im looking for a quick street car nothing race only,

The 307 HO is known as the "9" motor and the other 307's are known as the "Y" motor.

The VIN will have either a 9 or a Y for the motor, the "9" motor had a better cam, great for the 1980's, but it's not the 1980's anymore.

A running SBO can be found, but it will take a while to find one. Took me 3 months to find mine. Sometimes you'll find a guy on here selling one. Craigslist.org is a good place to look as well

Jeg's has the kit.

There are places the sell SBO and BBO crate motors, you'll have to "Google" it. They aren't cheap

Why would you change anything when it only has 15,000 miles! I know its your car but if you do plan on an engine swap, do not butcher anything and keep the stock engine. Luckily an Olds 350 will swap right in with no modifications. Try not to change anything on the car that you cant undo. These cars are getting hard to find with such low miles and in good condition.

i agree im not doing anything i cant undo if i swap it out, i might just sell it and get a early 70's 442 to hurst/olds but this is my grandpas old car...i inherited

Why sell your car to get a toy exactly like everyone elses? I know there are plenty of G bodies out there, but I think you should keep it, especially, since it was your grandfather's car.

Why sell one?
Just have TWO, like I do!!!
