I know nothing about it except it is very slow.... VERY slow. I just picked up the car and have been using it as a daily driver. I have been thinking motor swap is the way to go. But for now can much be done with the old 307?
http://performanceolds307.tripod.com/ I read all of that website when I was thinking about getting an '82 Park Avenue. Not a whole lot you can do, but I did a google and they have a 300hp turnkey engine http://www.proformanceunlimited.com/specs/oldsmobile/307_400HP.htm check it out
Recurve the distributor, open element air cleaner assembly, and, if it doesn't already have them, add duals. :TU: Depending on what kind of gear you've got out back, you might want to find a 3.42 or 3.73 gear set. Have you got the 4spd auto? Post pics, if you've got any! :TU:
biggest problem is heads and intake i heard 350 heads and intake will fit 307 motors do some research cam and crane 1.6 rockers
I had a 307 Olds a few years back..a good runner.. but a dog. I would not waste the time or $$ on it. I believe the design (bore/stroke/heads) is not really geared for performance anyway!! What about a 350??..more cubes for one :TU: Later,Tony.
Drop in the Olds 403, a much better engine. Or, a SBB, or BBB The Gutless Cutlass 307 motor is useless except for gas mileage and longevity.
The 442 got the better 307. The garden variety 307 was the engine code Y. The 442 307 was the code 9 I believe. The 442 also got the 200R4 with 3.42's out back which helped alot. I had an 86 Regal with the Y motor, a 200C, and 2.41's, and it was the most gutless car I've ever had. The engine literally stopped pulling at 3500 RPM. I thought the Trans Ams got the 403o No:
the 307 in My 84 Le Sabre does well in the mileage department and it will do even better when I do the decomputerizing, soon as I get the parts lined up for the swap
Don't put any money in the 307 just drive it while you build something else. Recurve the distributor maybe some things that can carry over like exhaust for a good sound and some gears or a whole rear. Lets see you already have a GN motor and an LS1 motor, very cool. Both of those should run hard and get good mileage. I would do a big block as they are entirely different in how they lay the power down and are a lot of fun as a change up from whats already in the stable. I would do a Buick 455 with TA heads and maybe a stroker crank or a big Cadillac with Potter's CNC heads and MTS drop in forged rods & pistons for a cheap easy drop together 10-1 517ci that kicks butt and makes people scratch their head.
Don't think you can even recurve those distributors, they used that CCC system that ran the distibutor advance/ timing. POS
if you replace the dist and carb from a non computer Olds engine, it bypasses the computer altogether. I have done it before with great results. will do it on my '84 Le Sabre 307 when I find another carb and dist.
I found a site that might help answer any questions. Go to http://www.442.com Just go to faq and click. This is were i found out some answers that i had about the 1968 350 olds that i am in th prosess of building for my 86/82 Regal.
take the info from the 442.com faq with a grain of salt, some of it is incorrect but no one has bothered to fix it. the 307 in my 83 is still nutless with 3.73s out back, ditching the emission crap, installing the non ccc carb and dizzy, and some exhaust keep it from being beaten by a n/a 3.8 but still cant perform. my 87 caprice wagon with a 307 and a broken stator is awful, it literally CANNOT back up a hill.
307 heads are all wrong for any sort of performance. 350 heads wont fit...its a stand alone motor made for the smog generation. From what i've heard, bore/stroke is also all wrong for any sort of performance build. Motor was built for low end torque (not much) all in at 2800 rpm. Heads wont flow crap, chamber design sucks, rods are weak and cam is flat. Don't waste a penny on that motor, find a 350 rocket and drop it in.
