We have been running an automatic in our hobby car, but I want to install a standard 3 speed. The engine is a late model ('86-95) 350 sbc. I cannot afford to buy and expensive racing cluth and press. plate. If i was to order a stock cluth/press plate what would i order it for? The tranny is and saginaw 3 speed. I will also have to get a new flywheel that will bolt up to a late model sbc.

As far as the flywheel, what you want is the light weight nodular flywheel, which is about 15 lbs less in weight than the stock one.
I paid $215 for it last year from gm parts dealer.

12.75" diameter, 3.58" bolt pattern, gm part number 14085720

If the starter has the bolt holes straight across from one another you'll need the 153 tooth flywheel. If the starter has bolt holes that are diagonal from one another you'll need the 168 tooth flywheel.

The above part number is for the 153 tooth flywheel that I used on my early '70's 010
sbc motor.

Don't let your starter limit you. Your local starter rebuilder can change the nose on your starter or any mini-starter will work.
The 15 lb. Nodular iron flywheel is available from Jim Pace Pontiac (They Mail order GM Performance parts at THE BEST prices) for about $152 in both flywheel patterns. Or you can find them used (I just bought a used one on E-bay on Friday for $62, couldn't pass up the deal, I'm putting together a StreetStock for my crewchief to have some fun in next year).
The Pressure Plate (10.5") you want is a stock replacement made by LUK. It's about $70 but only weighs 13 lb.(only 1.5 lbs. more than 10,000 RPM's $300 piece).
An alternative to the GM 153 tooth is a CAT billet 153 tooth I have seen them for as little as $80 new.
Good Luck
