I used to have a SHM motor but a rod bearing or something went out so I just wanted to get rid of that motor since it never really ran right to begin with. The new motor will have 415 hp to the crank which was a lot better than the 251 rwhp that I had with the SHM motor. The new one is built for boost so I think I might just have HP Performance twin turbo it while it's there anyways. But what I wanted to know is what the 1/4 mile times would be around with the 415hp, thanks.
