If anyone is doing an engine swap on a fwb with the 307 in it headers will fit. I got a pair of flowtech and they are snug but fit perfectly. I dropped the new motor in over the weekend now I have to start hooking everything back up. I have come to terms with the fact I am going to have a check engine light on. But I just need to find out what vacuum lines I really need for heat and other accessories.

Its really easy to pull the top dash pad and disconnect the wire going to the bulb, just tape it so you wont have a rattle.

Or even easier is the Homer Simpson method, just stick a piece of electrical tape over it.

Are you using the 307's computer controlled carburettor and the computer controlled distributor?

If you have done a way with the e-carb and installed a vacuum advance distributor (you should have), then you can disconnect the computer (because it probably won't work with the 307). The only thing you would have to do is rewire the relay for the A/C Compressor Clutch; the computer supplies it ground, so you would have to ground the relay.

Get an antiquated vacuum advance distributor. The computer will not have enough information to advance or retard the spark, and you will never be able get it to run correctly.

just wondering (I may have missed it) what motor are you putting in?

If you're changing the carberator do what sven914 said and get a regular distributor for it. What's there now works with the carburator. The computer controls the timing based on what it assumes the carb is doing and it will mess things up even more when senors aren't picking up what they are supposed to.

I too am having trouble keeping track of who is swapping what engine it what. If I'm not mistaken, jcolliga swapped a 368 for a 307, but he could also be to one who is building a 350 (from a 307) or even the one who is having problems installing a 305.

I have a machined olds 350 and already took out the Oldsmobile 307. Any suggestions on a distributor?

The carb and distributor from the 307 ;)

^Do that and your 350 will suddenly feel like a 307

For a distributor, you could go with something like this one (http://www.kmjent.com/cart/product.php?productid=588). You can look for other brands; there are a few companies that make aftermarket performance distributors for Olds engines.

I wouldn't suggest the carb and dizzy from the 307. I did that and my new Olds 350 felt the exact same, even with a better cam. Couldn't even do a decent burn out, just like the 307. If I did it again, I'd put an edel 1406/7 on it with a vacuum advance dizzy. You will have to leave most of the sensors for the computer unplugged but you will have power.

Ya I plan on leaving most of them unplugged. I am even considering running a few gauges from water temp oil pressure and one other I can't think of Right now. If I am able to run a manual oil pressure line off the block that would be.nice. I liked that dizzy You recommended Sven have you had any luck with that one in the past? Also where does the vaccum line go to from the dizzy?

You can use the temp and oil pressure sensor from the 307, just not the O2, TPS or IAC.

I got the flowtech headers for the Oldsmobile 350. You can get them plated how ever you want I forget the part number I will check tonight when I get home in my stack of receipts
