Ok guys I have a new problem for ya. My new 408 stroker comes apart around 63-6500rpm. It's almost like hitting the rev limiter but more nasty.
The weird thing is it almost seems to come and go.
Before my engine was a 340 with the same top end and camshaft and I never had this issue.
I'm hoping it's not valve float!
Here's my set up
Scat stroker around 12:1
Lunati 60405 cam hyd flat tappit
Eddy rpm heads. Looked over by engine builder but not re worked
Holley 750 dp
Msd billet dist
Msd digital 6 plus
Timing set 34 total.
94 octane gas. Most I can find here in calgary
