Yep....fired up the 408 today on the test stand I built and it runs great....no leaks, fairly aggressive idle and snappy as all get-out....oh yeah love the tunnel ram and 500 avs's

Now....after a good 20 minute run-in @ 2000 rpm and a few heat cycles....i ck'd cranking compression and all holes are between 205 - 210

Best guess on compression is somewhere around 10.5 - 11.1 flat top icons / 5cc reliefs @ zero deck.....J Heads 2.02/1.60 midly massaged that have been decked a few times throughout their life and uncertain on volume...????

Erson Cam: Intake 312/504 Exhaust 320/517 110+4 Gross Lift: Intake 335/248 @.050 Exhaust 345/256 @.050

Timing is locked out for now at 32* w/10* start retard, the MSD E-Curve works flawlessly and not a hint of detonation on 93 pump swill with zero load of course.....will it live on 93 on the street....?????

Keep in mind the 64 Valiant will probably end up weighing at close to 3000# 4-speed and 3,23's w/27" tires

Engine builder seems to feel it will be A/OK.....what are your thoughts ??????
