SB Chevy backfiring on startup
I have had a few problems with my 327 chevy backfiring on startup. This time it blew the chrome rocker covers off, bending the rocker cover bolts and the rocker gaskets flew completely apart! Lots of smelly smoke too.
It has a 600cfm Holley and a edelbrock manifold and headers. I did a compression test recently and it ranges 140 - 150 between cylinders. I have just serviced it with new filters oil and plugs. Oil and water look fine.
The engine was running really sweet when I took her out yesterday??
Please help
Good to have her home finally, still need to go back and give her another polish after messing with the engine stuff. Made it up to Idaho. Also a local show.
New guy from Utah.
