I'll be priming my 400 stroker soon. Also, would it be a good idea to mark the distributor in relation to the block jst to get it started. Then use a timing gun to time it correctly?


(1) turn dampener slit to TDC on the tab (#6 compression) which it will already be at if you left the timing gear dots at 6 and 12 0/clock. (2) (preoil CCW) (3) turn dampener CCW 3/4 of a turn (17.082" around the circuference with a measured strip of paper) (4) preoil CCW again (5) turn dampener CW forward 3/4 of a turn till the marks are at 15 BTDC (#6 compression). (6) clock intergear (anywhere)/install dist so rotor is under the #6 dist cap plug wire/terminal with the vac adv can in its normal BB position & maintaining the OE plug wire position is a good idea (clock the intergear to get it where you want it) & on a BB #6 may be sideways out to the pass fender but check on that (I ain't a BB guy). (7) turn housing slightly till the magnet is lined up with the tooth (rotor still under or close to under #6 plug wire terminal) and the can will shift phasing CW on a BB from its at rest position if it ain't close as is. (8) set reluctor gap at .008" (9) make a mark on the dampener 2&1/4" CW from the OE slit & have your dist guy set the timing to that when it fires (vac adv capped) for the cam breakin.
