Sorry I can't see them, my hotel connection is terrible.
Keith, how many SOHCs have you built? Seems like quite a few!

We have built 2 with 2x4 intakes, 1 with Twin Paxtons, 2 with Hilborn efi, and we are about to get started on a Hilborn CNG Injected SOHC.

What a beast Keith! Trying to envision being in a little Cobra with that monster hitting the red line. Scary thoughts enter my mind!

Your first video:

...at about 20 sec reminds me of the song lyric - Goodness gracious great balls of fire!
Thanks for sharing. |

Any postable dyno charts Keith? Interested in what the torque curve looked like.

Always been curious how often you need to measure the stretch on that long chain, particularly after a hard run like that. No expert on cammers, but I imagine that the tensioner pulleys take care of things for a while. What is chain maintenance like?
