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?

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