Here's as close as I can get, with a clip of my car at the track. Notice who smooth it idles, rpms barely change at all when it's put in gear.

Timing is only set at 10 degrees, no want or need for any additional timing from the vacuum advance, although I use one to add about 10 degrees timing at cruise via ported vacuum.

In this clip the engine is actually "de-tuned" slightly, 100 lbs added to the trunk and short shifting at 5000rpms to stay roll bar legal and keep the track Officials happy.

The time slip below is 1/8th mile, in hot/humid weather, and shows the potential of the combination better than the video of the track run.

My combination is the very popular KRE heads by Dave at SD ported to around 295cfm, 455cid, and his "Old Faithful" camshaft. Mine is the 112LSA version, and the ICL is set at 109.5 degrees.

No "lope" at idle or "stinky" exhaust here, the engine is very efficient, and actually gets excellent fuel economy although I don't drive it long distances very often due to running DOT's on it that cost over $400 a set!.......Cliff
