last week I hit the wall head on at about 60 miles per hour. Is it possible that their could be damage to the pistons or other engine components? I run Speed Pro Hyperutectic coated pistons.

a few years back at boone, jason pike hit the light pole and broke it in half. i think it was jr. motor sports that took the engine back to see if it had done any internal damge, so i would have to say that there is a chance that something might have tweaked

I wouldn't think a piston or rod would break or bend but a cast crank (scat 9000, stock GM) might bend. I'd pull it and have everything checked before you race it again, better safe than sorry.

Did the motor instantly stop or keep running for a couple seconds after hitting?

Usually they're ok. Maybe take the plugs out, make sure no liquid is in the cylinders and turn it over by hand with no plugs in it. If it doesn't have a tight spot, you're more than likely ok.

if it is a claimer type motor and has a cast crank i would double check is very easy to twist i-beam rods and break cast cranks with an inpact like that.i have seen them break from getting on the brake,and then stabbing the throttle real hard..better safe then sorry like mentioned above

The motor did stop instantly because I think I hit the brakes just as I hit the wall. I am concerned about the engine but the car did need to be reclipped. And yes, I am hurt but still would like to get the car back on track

WTG Dasher! I did one of those head on's into the wall and was still in physical therapy when the re-clip was finished. It's amazing what a lot of determination and a good set of crutches can accomplish.

I have personally never heard of or never seen a piston that was broken as a result of a crash. External damage is common to see, and in one instance I have seen scuffed main bearing's on number 2 main journal (where the motor mounts bolt up), but this was on an aluminum block. So barring any direct wall impact on the nose of the crank, I seriously doubt if you will find any problems. I'd personally rather have one shut off instantly than end up with the throttle hung wide open until someone gets to the kill switch.
