Re: Crate 350 in 85 k5 can’t get up to highway speed

Thanks for the feedback, timing is set to 12 before TDC. I’m gonna take a look at plugs this afternoon. Carb hasn’t been messed with just yet. What’s interesting is I don’t feel a substantial power increase with the 350 over the 305 that had serious cylinder water damage on the passenger side head that limited any good compression and tons blowby.
