Need advice...

Found out some nasty news today....

Long story short, I had a 94 Mustang GT, I recently sold it to my Dad, who blew the head gasket while driving on the racetrack... We thought it was a blown head gasket... but I just got the heads off today, gaskets were fine, but Two pistons had chunks missing from the right side..... Coolant in the same cyl's as well... The #3 and #4 cyl's I believe <two closest to the firewall on the drivers side>

So I'm assuming it needs a rebuild.. Piston replacement at a minimum, correct? It's a 337 Stroker <modified from a 331, not sure what was done, this is what I was told by former owner>

Would you all recommend me attempting rebuild myself? We're on an extremely tight budget here... I've never had experience inside an engine previous to this though, and don't have any friends local who could help me if I got stuck...

Or should we go ahead and have the shop that built it do the rebuild (True Blue Performane, Raleigh. NC)

#4 spark plug was melted when I pulled it out, so I'm assuming this was the cause of the problem? Or maybe a consequence?

I appreciate any help...

Good idea.. I think since I've never rebuilt an engine, and know nothing about assembling one, I'll suggest he have the shop that built it to start with rebuild it... Especially since this is his track vehicle, and how well it's built matters.. a lot, lol The money is the main prob though

We'll see what happens... thanks for the reply

I wasn't aware of Rick91GT, or his knowledge.. Thanks for the pointer. I'll probably hit him up for tips if he doesn't stop in.

I also appreciate the well wishes... Definitely needed here
