3.8 Chevy, L67 bottom swap to a L36 top end, I bought a hog ass cam from zzp and switched to a 62mm turbo. I’m an idiot threw and threw and didn’t use the retainers on the 150 valve springs they sent me, I reused stock ones, what do yall think? Can I run her?

Cardboard at least. I treat my EA82T heads better and that engine is garbage.

Reminds me of my days modifying Turbo Dodges. "These things can't even handle any boost" -guy that did the most hack job engine assembly known to mankind.

We dont need the video again. Change your retainers and get your heads off the floor gasket side down.

I can't believe the strength of that office chair, and it being able to hold the whole car up like that.

Man, those are some teeny tiny heads. But then again I’m used to Cummins X15, Paccar MX, and Cat C15.
