    2004R Questions

    There are 2 differant cases used for the 200R4. The BOP case has 7 bolt holes on the bellhousing mounting flange. This transmission will not bolt up to a small block Chevy. The case that you want is the dual use case that has 10 bolt holes in the bellhousing flange. Do not count the 2 guide...

    New member, got a few questions

    You can spend a lot of money now and more time driving or less money now and more money and time in the garage. If you buy a like new '78 for 15,000 you will be money ahead than buying a 2,500 and putting 15,000 in to it. Now that we've made that disclaimer I'll say that I have gone the...

    Which Water Pump

    The small block Chevrolet engine used one of 3 water pumps over the years. They are referred to as short, Corvette, and long. The short and long pumps used a 5/8th inch diameter pilot shaft at the fan attachment. The Corvette pump used a ¾ inch diameter pilot shaft to mate to the fan...

    1980 alternator ouput?

    You can also check with these folks http://www.alternatorparts.com/gm_alt_repair_upgrade_kits.htm They offer kits that you can install in your case to increase the output. I have to agree with the above response about going back to a standard pulley. Do NOT use a 1 wire alternator as they do...

    high compression

    It's just a matter of selecting the right camshaft to work with the compression ratio that you have. My static compression ratio is close to 12 to 1. The dynamic compression ratio is about 8 to 1 due to the 300/310 duration camshaft that I use. You can read more about dynamic compression...

    12 Sec Car

    My best times so far with my '79 that used to be an L48 and Turbo 350 is a 12.80 on real street tires. Looking back on it I would have to agree with the above suggestion to buy a crate engine. My current setup is a 406 small block that shows 480 HP on Desktop Dyno. We have to deal with a lot...

    Too much cam...too little vacumn....

    All of the "experts" will tell you that a stick shift car can handle a bit more camshaft than an automatic equiped car but I really think that what matters more is the fact that your '73 is at least 500 pounds lighter than my '79. If we were to line up at the drag strip you could launch at a...

    Too much cam...too little vacumn....

    The specs on that cam are 234/244 @.050 on a 112 lobe center. It is a hydraulic lifter cam. Seat to seat it has 89 degrees of valve overlap! You might want to download a program called Dynamic Compression ratio and run it with your numbers. I suspect that this cam will make VERY LITTLE...

    Too much cam...too little vacumn....

    The cam that you are using is only going to work with a large displacement engine with a lot of static compression. As an example the cam in my 12 to 1 static compression ratio 406 small block is a 300/310 on a 114 lobe center. I have 10 inches of vacuum at idle in gear. The reason that I can...

    Too much cam...too little vacumn....

    I have one in my '79. I no longer use it since I have converted to a Hydro-Boost unit. The vacuum can worked OK for most uses but if you were in heavy traffic, like leaving a cruise in or on a poker run it would run out of vacuum on the second, third or forth use of the brakes. You never knew...

    HELP Removing Power Booster Please

    Take out the vent tube going to the left side of the driver and the trim panel below the steering column. That will make it a lot easier to see. I used a 16 inch long extension and a socket with a U-joint. Depending on what year your car is you may have 2 nuts on one stud. The top nut holds...

    C3 driveshaft removal

    Slide the transmission yoke foreward all the way, remove the rear U-joint cap bolts and drop the driveshaft down at the front. It can then be slid out the front below the transmission.

    Yep, I've been there too. Just wait until you drive the finished product though. You are going to love it.

    solid mounts vs stock mounts

    I was always told that you had to use a solid transmission mount if you used solid engine mounts. I have ridden in a car equiped with solid engine mounts and could hardly tell an increase in vibration but I put it down as a real good engine balance job. Maybe the solid mounts arn't all that bad.

    Dumb Question

    The "stroker" is in referance to the crankshaft. In the case of a 383 it would mean that you have bored the cylinders out .030 and replaced the 3.48 inch stroke crankshaft with a 3.75 inch stroke shaft. The 3.75 inch crankshaft came stock in the 400 small block that ws used in 70's Chevrolet...

    Please dont ever do this!!!

    The stock Corvette fuel pump provides 6 psi and has a return to the fuel tank to lessen the chance of vapor lock. The same stock pump that works on a stock 350 is also used on the high performance big block engines.
