Ok, so about three months ago my stock 5.2 liter V8 dodge
engine blew. I got a jasper engine under the hood now, but it just seems like the total performance aspect of the truck has gone down. At the track it's only hitting around 110 when before i could max out at 120, and in the 1/4 mile it barely spins the tires when i floor it from a dead stop. Everything about the truck is stock besides the engine. Any reason this is happening? any way to fix it?
