Apparently not enough... :roll: How much boost does that turbo generate when the butterflies are opened?

The 3800 Series II swap into a G-body has been done many times, especially with the L67 SC motor. There used to be a very detailed website by someone who had done the SC swap into a G-body Cutlass, but that site went away with AOL Hometown, unfortunately. The GN crowd has used the Series II...

The fundamental problem is that a real emissions test that verifies compliance only through a tailpipe test takes a couple of weeks and costs several thousand dollars. The sniffer test that emissions test shops run is a spot check. It only tests emissions at idle and at about 1700 RPM under...

Well... Trans adapter Different exhaust Different starter and wiring (it's on the other side) Different accessory brackets Different wiring and hoses to the accessories (they are in different places) Different motor mounts Different engine-side mount brackets (Chebby uses the rubber mount on...

Sorry, but I call BS. The difference is about 30-40 lbs. You do NOT need to change suspension and brakes. In fact, put an aluminum intake on the 455 and the weight is about the same as for an SBO. Use aluminum heads and it's lighter. I have personally weighed a bare 455 block and a bare...

Re: Anti-Freeze leaking from ABOVE my Trans. 86 Cutlass 30 The first thing to check is the heater control valve located at the rear passenger side of the intake. This is the most likely source of the leak.

There is no reason to use a one-wire alternator, especially if the car already has a three-wire SI-series alternator. You'll loose the GEN light function and depending on the quality of the one-wire alternator, it may not charge at idle. If you want a high output alternator, get a three wire...

I lied. Here's another post. Would you be happy with materials properties references from MIL-HDBK-5, Rev J? Typical mild steel (4130 or 4340), such as would be used on the wheel and the hub, has a CTE (coefficient of thermal expansion) that varies between 6.5 microinches/inch at 0 deg to 7.5...

One more time and I'm done. With steel wheels and steel lugs, there is ZERO relative growth between the stud and the wheel. That's physics. With aluminum wheels and steel studs, there is 0.001" growth in the thickness of the wheel relative to the stud. That's well documented engineering. If...

Sorry, but your logic is wrong. Let's consider your race car with steel studs and steel wheels. Your're suggesting that the looseness of the lugs is the result of thermal expansion? How is that possible when both the studs and the wheels are steel, so the expansion rate is exactly the same...

Actually, an LS1 swap is completely legal in CA, so long as the motor is from a car and you transplant every single bit of emissions equipment from the original installation. The basic rule is that you can always swap a newer, cleaner engine into an older car. You just can't swap engines from...

Wow. I guess you never use aluminum wheels then, either. Check out MIL-HDBK-5. You'll find out that aerospace grade aluminum spacers/adapters (7075, for example) have a HIGHER compressive, tensile, and yield strength than the mild steel hubs that they are bolted to. As for hub-centric...

First of all, do not buy "cheap" wheel spacers. They are cheap because they are crap. On the other hand, do not condemn all wheel spacers either. There are well-made machined spacers that have the correct hub-centric features to ensure that the wheel is correctly and safely centered. These...

Summit and Jegs both sell a simple bolt-in bracket to use the 200-4R crossmember in a pre-84 G-body.

I think the stock 305 ECU should run a relatively stock TBI 307 with no problems. Use the CCC HEI distributor from the 307. The ignition module has the same terminals as the Chevy TBI module, you'll just have to change the connector. Be sure you get an ECU without VATS or else one that has...

I suspect you are right. First, the two wires connected to the pump use factory Packard 56 terminals, but they have been removed from the OEM plastic connector body. That makes me think that the previous owner installed this pump when the factory pump stopped working and simply removed the...

So long as he knows he's spending $25K to get a $15K car... Not that I'VE ever done anything like that. Oh no. :wink:

I hate to say it, but if the car is really rusty, it's not going to be cost effective to repair it. I have this problem with my 79 ElCo. The sheet metal panels will cost more than I can buy a nice one for.

To answer the original question, no there is no way to tell what kind of car that motor came out of. The block casting number is the same one used on every single 350 built between 1968 and 1976. The #5 heads were used on every single 350 built for the 1968-69 model years. The only way to get...

This may sound a little harsh, but if you want to help your friend, teach him how to use Google. There are many, many Oldsmobile-specific sites and vendors on line.
