3.8L (229 CID)The 229 cid (3,751 cc) engine was first introduced for the 1980 model year and was produced until 1984. This engine replaced the 250 cid in full-size Chevrolets and Camaros as the new base V6. Additionally, the intermediate Chevrolet Malibu and Monte Carlo also used the 229 cid as a replacement for both the 200 cid V6, and the 231 cid Buick V6. Both the Buick V6 and the 229 cid Chevrolet V6 are 90-degree V6 engines, and both are often referred to as the 3.8L V6. These engines should not be confused as being the same, and are completely unique engine designs.
The 229 cid has a 3.736-inch bore and a 3.48-inch stroke, identical to the Chevrolet 305 cid V8 engine. The 229 cid used the same 2.45-inch main bearing and 2.10-inch rod bearing diameters as the 200 cid V6 engine. Also like the 200 cid V6, the 229 cid used the same crankshaft with the 18-degree offset throws and the same 5.7-inch connecting rods with 0.050-inch narrowed ends. It came equipped with 1.84-inch intake valves and 1.50-inch exhaust valves. The 229 cid V6 was only equipped with a 2-barrel carburetor. For 1980 the 229 cid used a mechanical Dualjet. From 1981 to 1984 the electronic Dualjet was used along with the GM's CCC (Computer Command Control) system. The 229 cid was rated between 110 and 115 hp (86 kW).

most likely a weak fuel pump or a clogged filter. Check fuel pressure with a gauge or as its bogging down spray brake cleaner in the Throttle Body. If this allows it to increase RPM then its the pump or filter.

This is a snap on cover that covers your old one without it's removal,just paint it to match.Now you can get these from a lot of different places and I'm NOT recommending any business or company,just saying this is an easy way to get a nice looking dash without replacing it.

Sounds like a problem with your choke. It may just need to be cleaned (linkages and all). If the choke doesn't close after reaching operating temperature, the engine will rev high. This indicates a choke stuck in the open position. Also, you may need to look for a vacuum leak if cleaning it doesn't fix it. On a 1981 GM product, I'd expect the vacuum hoses to be stiff and cracking.

go to your local part's house and get a Haynes manual. it should have what you need.

nice choice of rod, but the v 6, junk , need to run untill 454,350, 396 arrive? cool, ok. only need dist vac to accelerater vac port pass side of carb,manifold vac port to brake boost lose rest.cap off.<check timing> racing trick, vac guage max vac back off 2 lbs of vac perfect timing for race. set wreckers up that way for clean burn and better milage.
