The pistons were at zero quench, so at full RPM they were very very close to the head, which is great.. however that doesn't leave a lot of room for loose tolerances in the rod bearing. it had a damaged rod bearing (low oil pressure at rev) and that combined with RPM stretch of the connecting rod allowed the piston to hit the head and shatter.
So I have a 78 f150 with a 351m your showing me it's worth dropping a built 400m in it!! Can or will you get specific on the motor build I'm extremely interested!!
Yeah I don't mind sharing my build specs. A lot of people keep asking, I'm thinking I'll make a little tech video on it and talk about the two engines I've had in it (400 and 523).. and the rest of the truck. I'll post on UA-cam and/or Instagram when I do it, probably this week.
Ahhhhhh! The beautiful sound of freedom🇺🇸🇺🇸🇺🇸🇺🇸🤘🤘🤘
What exactly happened to your engine? connecting rod piston overheated, head gaskets?????????

goddam! but you're right time to rebuild. Try something new... maybe different cam and can you stroke it? Supercharger? Stick with the 400.
Keep that 400 and slap a nice single turbo, lookin at 6-700 horse then.
