Alright brothers, I got it started early and I will leave you with a complete run down to ensure I don’t miss anything.
Went to parts store to get pcv valve to help pressure, went ahead and got my rebuild kit for my carb while I was there.
When I got home I pulled the plugs and checked, (Again this motor had less than 3 or 4 hrs running) they were nasty, a lot worse than they needed to be. I started to check pressure, and noticed a few where only hitting around 115, while the rest where 135-140. So I put them back in and fired it up and that is when it sounded like a bag of marbles was released. So I pulled the covers and noticed the 3rd cy (P side third back) rockers was way lose, but the rest where fine, or tight that is.
So I knew what needed to happen, and about an hour later you see what happened. That cam was brand new crane, I will leave specs below again, because I have want to ask for thoughts on hyd cam. I am not trying to go stock, but this car will never see a track, and of course street racing is illegal,lol.
I have seen them many times burn through one lobe but three, hey there is a first time for everything. I know my numbers where correct when I built it, but when it rains it pours,lol.
I am in need of some good parts, and need someone to throw me a bone on where to go too many places are good for some and horrible on others.
Cam int .280,/ valve int .485 /advdur 284*timdur int 208*/ open -3*BTC close int 31*/over lap 62*/ center 107*
I am scared of putting too big of a cam in there after this happened could use some help to ensure I can focus on the prize at hand.
Maybe I made the mistake by not changing my push rods, or I am overthinking this way beyond what I need too
