what would you concider
what would you concider as far as excessive timing chain slop. I talking in degrees. also do you know if a 89 351 came from the factory with a roller chain? or silent type with the nylon coated gears. or was that just for the mustangs

Well actually some police mustangs did have 351s I know I had 2 of them. but what I really meant was from what I was told was the 302H.O. motor used a roller chain from the factory . and the rest of the fleet used the regular type chains. is this true? do you know if the truck motors were roller chains from the factory?
you guys still never really answered the ? OK when I was checking the slop in the chain I was using the degree marks on the balancer and I was monitering the movement of the rotor. what would you concider a sloppy from when the crank moves to the rotor movement. like how many? if any degrees?
do you know if the truck motors were roller chains from the factory?
you guys take everything to literal

roller chain was factory for most Truck engines 302 from 87.to 96 ,,Some *87-91 were lucky enough to get a roller setup..
92 thru 96 302 was slightly different from the 87 thru 91 model of the 302.. as for the 351M it also came in the same cfg roller chain and non roller.. the 302 H.O. came with roller rockers and so did the 351M.
As for the mustang yes it had a 351M as the power plant came in the police interceptor an a few packages had it included..from 87 and up...
As for your Question regarding degrees of play you can get away with 2* of deflection (1/2" in the chain max) max meaning that if you had the cap off of the dizzy an placed the engine into TDC and moved the balancer and measured amount of movement before the dizzy rotor moved anything over 1 degree is to be concerned and 2 or more would require timing chain replacement as a rule of tumb.. ( using the dizzy as a compass 360 *degrees)
