Im going to buy my parts for doing the timing bump on my truck and just want to know if what i picked out will work or if anyone is currently running these parts let me knows thanks.

Parts for a timing bump??? dude what are you talking about? use a timing light and a 1/2" wrench, pull the SPOUT connector out, change timing to 13-15* BTDC lock her down, replace spout, fill with 93 octane and roll!!!

sorry first link didnt work try these ones Thanks.^^^^

That would be an ignition upgrade and yes MSD stuff is good.

talking bout a high output coil better wires and copper core plugs so you can jump a bigger gap and bump up the timing to get a better burn of fuel out of it with out getting detonation. and some more power.

i have a 48k volt coil and all that stuff, bigger gap all done correctly as many of these write-ups state...no cigar. Now it may work for you but my timing is about 14* and I need to retard it, again.

MSD makes great stuff. I just installed the MSD Street Fire Coil, MSD Cap & Rotor, Accel Plug Wires, Autolite copper core plugs. After the Install of the new Ignition parts, you do not need a timing light to advance the timing....every engine will be different due to carbon build up in the cylinders (slight higher compression).
You can mark current position of distributor, then just keep advancing the timing by turning the distributor clockwise a hair at a time and starting the engine with every slight turn of the distributor till you hear a clatter / ping when the engine is started or with slight load... then just turn the distributor a hair counter-clockwise till it starts fine with no noise... this is how we use to get the most advanced timing possible at the race track. You should notice it pull a lot harder & if you hear a ping or clatter when accelerating just back it off a little more. When turning the distributor just make sure it is always in very small increments.

Also higher mileage engines do not like low octane fuel you can try octane boosters to help with pinging. The copper core plugs will help due to their expansive heat range along with a upper engine cleaner to knock some of the carbon out.

I did the timing bump on my i6 and am pleased with it. I wish I would have used motorcraft copper core instead of autolite. Along with the 48k coil, 8.2 wires, copper tip rotor cap and button; I gapped my plugs to 60 and bumped my timing to 16 degree. Had my doubts of difference when I first started it but once I hit the gas and lit up my tires out the driveway, I was convinced that the money was well spent. Not alot more horses but enough to notice the difference. Just wish my i6 could rev over its normal 3000 rpms. Good news is that it still passes Marylands emissions with flying colors. Down fall is needing to run 89 octane.

Thats why I went up to 14 deg BTDC with a 0.050" gap which i think is just borderline so i could still run 87. Anything higher and I can hear the knock under load.
