how do you upgrade a firebirds engine from a v6 to any v8
I have a v6 Pontiac Firebird 1996 and i need to know what I would have to do so that I can be able to put an engine bigger than the current from a v8 4.8L up to a 6.2L

The 1996 model brings with it some additional options as well as some newly standardized equipment. The 3.8-liter V6 engine which was optional in the 1995 models, is standard in the 1996 base model, and the Formula had its 5.7-liter V8 enhanced to 285 horsepower (305 in the Trans Am).
As always, the Firebird's big engine is what distinguishes it from other sports cars--especially those in its price range where it remains unmatched in value. Alloy wheels with painted surfaces add a sleeker look to the pony car. A variety of packages were available to sport up the look of the car, as well as to add some nice features, such as more engine power, traction control, and remote keyless entry.
Minuses of the Firebird include a failure to adhere to slippery roads (especially in Winter) and a lack of passenger and cargo room.

Two hoses coming out of the side of the idler pulley. Looking for replacement parts, plastic clamps broke, hose is worn and leaking.
I have a '96 Firebird with the L36 3800 Series II. When i bought it I thought it was a little hard to start but chalked it up to the fact that it had been sitting for nearly a year. Seemed to drive fine and ran well. Shortly after turning 100 miles of my ownership, things started to get wierd. It started with an odd rattle from the engine. I took it to a few shops for the old "what does it sound like to you" test and got answers from a torque converter to camshaft problem to bad accessory pulley bearing. I started to pay better attention to the gauges and sounds while driving it. I has the rattle at idle and at around 2000 rpms in P or N. While driving, it appears at around 4000 rpms right before it shifts gears. Oil pressure is varied from 60 psi while driving to 30 at idle. SES came on and scan showed two O2 sensor code. This morning I replaced the two O2 sensors and drove it abit. I took a right hand turn and the car started loosing power. SES started to flash and oil pressure dropped to 0. I pulled over at a service station, checked the oil (which was full) then limped it to a friends shop (1 block away) at 15 psi of oil pressure. I kept the idle abit higher to keep some oil pressure going. I was told the oil pump probably failed and my have been the noise I heard all along. It still has 0 psi when not on the gas but a small amount of pressure if you keep the r's up abit. Just wondering if anyone has run into an oil pump failure and if so what symtoms did they observe. I hate to order all the parts, have the shop rip down the front of the motor and replace all this stuff if it was not the main problem. Also, would anything with the oil pump cause a hard starting problem?
My '96 V6 firebird has been having trouble with misfiring. i plugged a OBD sensor in it and at first it said cylinder 1 was misfiring, it worked well and did not seem like there was a problem. It ran great and on all cylinders until i washed my car, and now it says that cylinder 2 is misfiring, but it only misfires on idle and when there is a load on the engine. i don't want to take it to a mechanic shop until i know whats going on and if i can fix it myself. What should i do to find out? or how can i fix it?
