OK, so I'm out visiting my brother near Seattle, and we're in the process of assembling his 340 and degreeing his Lunati voodoo solid cam. Adv 264/272, 235/243@ 050, 525/546", 106ICL recommended install.
We ran through the cycles about four times now, and we came up with 117* ICL! Measured 050 numbers on either side of the lobe were either
153/83, or 152/82 depending on how I held my tongue...we also eyeballed the timing wheel when the dial indicator maxed out and, it definitely looked as though ICL was about 117. This is clearly pretty retarded, and we only have a 3 keyway timing set.
We're going to go ahead and swap it to the 4* advance slot and see what we come up with, but would you guys think it to be OK to run it as much as 7* retarded in a 10.4:1 340 with Edelbrock heads? Or should we be looking into a new timing set?
This is a freshly machined engine with new OOTB heads going in a '72 Scamp with a 2500 stall and 373 gears...street going car...
Any help greatly appreciated...
