403 engines are found in GM cars made from 77 to 79. These can still be found in the yards. E-Bay would be my last resort. Try Hemmings Moter news magizine. 350 or 400 intakes will fit.

Small block or big block, matching numbers?

Don: You can still find these in the yards. Where are you located. Mike

Post some pictures, maybe someone will know what you have. Mike

Radials handle better and have better traction. Radials also wear better. If they were an option in 68 and you can verify it you will not lose show points. I thought radials came out in the early 70's. But I was in Juiner High school at that time. Bias ply tires are easy to spin for burnouts and make a wonderfully loud sqealing sound. Mike

If you machine the crank the heat treating is lost, as it only treats the surface out of neccesity. If the entire depth was treated the steel would become brittle. At 500 horse take no chances. Good luck, Mike

I will tell yo what is rare, if you can find one at all. Back in the old days we had what was known as a Full service Gas station. You pulled in, did not get out of the car, thsy pumped the fuel washed your windshield and checked the oil. All this was done at 29 cents a gallon. I bought fuel today. 10 dollars got me 3 gallons and a clerk that had never heard of full servic. Mike

OK MJ. You do not state what mobel of Dynamic 88 this is.The Celebrity Sedan weighed 4111 lbs and they made 38742 the Holiday coupe weighed 4079 lbs and they made20768. Holiday sedan 4148lbs and they made30784. You did not state convetable but let me add that in, at 4158 lbs and production of 5540. This information is from Setting the pace written by two long time former employees of Olds motor Works. The records do not discrimenate beween four door models and two door models.However it can be presumed that Celebrity sedans were post cars and Holiday sedans were built with no post at the doors.A Holiday Coupe is a car with two doors and no post. Figure it from here, good luck, Mike

The above message should have been addressed to Conni.Mike

Julian. Before taking any drastic measures, check your personal messages for how to flush out sludge from an engine. Mike

dwell angle is 30 degrees, manul trany is 2 degrees BTDC AT 850 rpm. NO SETTING SHOWN FOR AUTOMATIC. ONLY VISTA CRUISER SHOWN AUTO WITH A/C AT 14 degrres BTDC AT 850 RPM. CHECK YEAR ONE , BUY THE CORRECT ENGINE DECAL AND IT WILL SHOW THE PROPER INFO FOR YOUR CAR. Mike

I have done this with no problems, be sure to tourqe the bolts correctly and check them again after running the engine and letting it cool off. There are no garentees you will not have a future poroblem. You do not state why you upgraded your altinator. Did you add some electrical options? A larger alt will do nothing for you if you did not need to change for electrical reasons. The battery will only draw what it needs and more available current will not be needed for a car that is not burning more electric power. Sort of like putting high test gas in a low compression engine it cost more but has no bennifit to power. Good luck, Mike.

Pick up a Hammings Motor News for junk yards that advertise vintage parts. 84 parts should be easy to find all over the country. Mike

Smitty: New bumpers can be bought aftermarket at Year One, or Original Parts Group just to name two. Check Hemmings Motor News magizine for other sources. Mike
