If it isn't close-as in 4-5 degrees--take the timing cover off to degree it in. I have a friend-chevy guy- who came to me about having trouble getting his 350 started. I asked what was done to it. He said big performance cam etc. I went over there and he had it running but very rough and backfiring. Cam off a tooth, timing too. how it even started was a laugh! I fixed them and told him to reach in and crank it it will start. It did. the look on his face was a moment to remember!!! He still askes how I did that.

The used chain showed to be roughly .5* retarded. The new chain was 1* retarded, which I corrected with an offset keyway. I verified my numbers three times. I just don't get it. Unless its just because the engine only has about 1 hour of run time and 4 miles on it. Perhaps the rings need to seat. I didn't lean on it too hard, but part throttle was definitely off. I guess ill throw it back together and see how it does. This was mainly a mpg build, however I didn't want to use the stock roller cam, as I figured that would make it even worse in the get-up-and-go department 1969 Nova 454/M21/3.31 Mild mid-11 second weekend cruiser 1994 F150 XLT Super Cab 2WD 5.0/4R70W/3.55 (Daily driver)
