hello everyone who reads, i have an 86 firebird with the 2.8L V6 engine, what kind of problems do they have? (if any)

meh, mostly just underpowered for the weight vehicle, but that was the designed intention.

so i should put something more powerful in it like a 305 or a 350?

Not really worth the work, wich is quite a bit. :2cents: This a FAQ thread that covers this to give you an idea of all that is involved with the swap.

why would it not be worth the effort? i can get a 350 small block for cheap that i can rebuild and even though im not a millionaire does not mean i cant do anything. i know there are different mounts to go in with the 350 and since its a late model muscle car i thikn it would be fun. you should know that little project that u fiddle around with all year.

Because it would be cheaper to just trade the car in and get one already with a V8. It's not just about swapping the blocks out, alot more is involved to the point that the costs outweigh the value of the vehicle.

personaly i think it would be worth it to switch out the v6 for a v8 if you want to but you will have to get a different transmision if it is a automatic car or at least a new belhousing, clutch, and flywheel if it is a manual. there would be other things that need to be changed but those are the biggest that i can think of off of the top of my head

ohh and the crank in the stock 2.8 v6 are known to be weak and prone to breaking that is what happened to the crankshaft in mine snaped clean in too

. you should know that little project that u fiddle around with all year.

:rofl:

What I do know is that little project gets fiddled with for a VERY long year (more like a few)
