AMS 2.3 Stroker sounds like a desiel...
I finally finished my swap and got everything all bolted up. My bottom end is a AMS 2.3 stroker, head, IM and TB is all stock. I'm also running 1200cc injectors with a 3582r.
Upon startup it sounded like a desiel! This thing sounds soooo bad. At first I though I had a bad bottom end, but I checked the oil, and there is no sign of a spun bearing. everything feels great as far as driving, but it just sounds so bad...
I did some research and I guess these ceramic coated pistons take a while to heat up and have some degree of piston slap... How do you guys feel about this?

I'm at work and will not be home until later tonight, but I looked up "Piston Slap" on youtube, and a lot of the inline 4 cylinders that have piston slap on there sound just like my car. is this normal? I spent so much money on this build, I hope I dont need a new bottom end.

Well you could have pistons slap if they ptw clearances are huge, and the ceramic coating isnt allowing the piston to warm up and expand like they are suppose to. Why dont you call up ams since they know the specs on your motor they should be able to help you out.
Did you buy the motor from another member or ams?

Make sure it is in time. I've heard noises similar to this and it was the valves lightly tapping the pistons. Eventually one gives up and breaks the valve head off and smashes it into the piston.

Yes Mellon did the scalling, and it idles fine.
The only thing I can think of is maybe I could have a **** load of bad lifters? I beld them per mitsu tech manual.
