  1. Does anyone have a picture of where to place the posi and jacking stickers on the decklid? Or, does anyone know which page in the assembly manual? Rich

    A few more ?'s

    The VIN will be stamped on a vertical machined surface, above the oil filter, right where the block mates to the transmission. It should be visible from under the car. The number you see is the build number which shows it to be Tonowanda built, (as were ALL big blocks then), on September 11. The CRN code is for an LS5, 360hp 454, used in a Monte Carlo.
  3. That little "hamster" has some big teeth. Chevrolet spec is 125-140 psi. Mine puts out 140 psi. It just takes takes time to get there. There is a schreader valve on the pump, so you fill it with shop air, and then let it do the rest. You can just fill it with shop air and it will work, as long as it holds air.

    70 ss 390 hp?

    The reason Chevrolet gave for the difference is the exhaust. The bigger the engine, the better it will respond to exhaust upgrades. The corvette engine, with the better exhaust, made power further up the rpm range. Look at the engine specs in the factory manual. The 360 hp engine is rated at 4400 rpm, and the 390 is rated at 4800 rpm. This explains the 30 hp difference, as much as the exhaust. An interesting note on horsepower ratings. They were basically arbitrary, and were "dialed" in to fit the application. In 66, the first 427 hi perf vettes were rated at 450 hp. GM Corporat
  5. GM does still has all of the information, (invoices, build sheets, etc.),and Pontiac will sell you their information. Chevrolet so far has refused to release the information due to the huge volume involved. But, they do have it, so there is still hope.
  6. If you are running a healthy small block, a 3.73 gear should be no big thing. I say put the gear in and let it eat. If you don't drive it that much, why the overdrive? I run 3.73 & 4.10 in 2 of my cars, and drive them anywhere. The extra RPM doesn't hurt. Remember, these cars are usually not driven much, so shouldn't wear out for years and years. Put the money into going faster. Big block!
  7. Stick trans and 454 use a cast iron starter nose. The 350 & 400 turbo cars use the aluminium "cross bolt" nose, and the powerglide cars, which use the smaller flywheel, have the "long and short" aluminium nose, same as Cadillac. The cast iron nose uses a slightly shorter bolt than the cross bolt nose.

    Color question

    The balancer is orange, the pulleys are 60% black,(slightly glossier than semi-gloss). The booster is cad plated, which is kind of a dull silver. The master is natural, bare metal. You can blast it and clear with semi-gloss, or paint with cast iron grey.
  9. I was speaking hypothetically. My blocks are fine.
  10. They make 2 different 400 yokes. One uses the larger buick, olds, pontiac, and SS454 u joint, and the other uses the standard chevy u joint. Most chevys, except for 454s and some other death ray engines, and later full size wagons and such, use the smaller, standard joint. The drive shaft will be shorter. You can shorten the shaft easily. Scribe a line lengthwise on the end you are cutting so the end goes back in the tube in the same spot. Either end will do, as long as no weights are disturbed. Then cut through the weld with a hacksaw or a whizwheel,About 1/16"-1/8". Knock out end. Cut the

  12. Go to the junkyard! Just about all of the full sized GM cars except chevy ran 400 turbos If I remember, the switch and bracket and wire connector are all the same. Two bolts hold it in. To set once installed, push square sliding part that sticks out of the back, forward into the switch. This may take some effort. Then floor pedal. Switch is set. One wire comes from Key On power to the switch, the other goes to the trans. There may be 2 terminals on the trans. One is for downshift, the other, timing delay. When the car is off, the downsift terminal will have some continuity to ground, and the
  13. Just a note about stamping engines; Chevrolet used a broaching process to deck their blocks. This process is very different from the resurfacing machines used in most machine shops, which are usually rotary cutters, like a van norman. These machines leave a very different finish on the deck surface, which will be seen by those who know what to look for. I have had engine pads inspected for this by potential buyers. If somebody decked my block, I'd want to know about it. Years from now, it could cause problems.
