From My experience I have gotten two different length cam dowel pins with most aftermarket cams 1 for EFI and the other for use with a fuel pump eccentric . Thank You 🇺🇲🇵🇷🦊👍
Regarding the stock configuration, the #1 cam bearing has a feed directly into the base of the distributor shaft via the slot on the backside of the camshaft thrust plate. There is plenty of oil getting to the base of the dist gear. People who say that the SBF dist gear is "splash lubricated" are just wrong. This mod is a bit of an old school mod that was sometimes (not often) used historically used where solid race roller cams were made out of very hard 8620 or 9310 alloy steel core. A "bronze" dist gear was for short term drag race. Replacement of the gear was frequent and expected. Anyone who has used a bronze gear on modern steel OEM hyd roller cam found out the hard way that old school bronze gears aren't for everyday use. A mod like this may extend gear life however note that the oil spray is on the top of shaft above the gear. Although Rob does not intend to use a dist, if one did with this mod, most of the oil will be flung off during engine operation. It should be noted that you are taking oil from the driver side lifter passage for this mod. The plug is tricky as it can interfere with the lifter and/or the dist drive gear. This mod should not be used as a substitute for a correct cam/dist gear combination. People today who entertain this mod probably suffered a dist gear failure or advanced wear due to material incompatibility, not a lack of lubrication. Most modern cam materials can use a dist gear made from modern melonized steel which will work on nearly any camshaft material especially Selectively Austempered Ductile Iron (SADI) cams, like Comp Cams ending in a -8. In summary, this mod is probably not detrimental if already accomplished but not required.

@@rdspeedfab Thanks Rob. I hope I didn’t sound critical of your mod. This mod is all over the internet and is becoming trendy. What’s old often gets new again as this is an old mod. Next time you have a SBF on the stand, look dead straight at that plug with the distributer installed. You will note that that a centered hole in the NPT plug biases the oil stream to the driver side of the shaft where the effects of the stream are hard to anticipate. Many yeas ago, when I did this, I had a machinist bias the hole to the passenger side of the plug and angled the drilled hole down to “try” and hit the top of the drive gear. Did it work? Heck, I don’t know. Readers who have performed this mod are probably spraying oil around the timing cover area and adding some lube to the timing chain and maybe the distributor gear. If oil pressure is good and the driver side lifters are quiet, then I would rest easy. I am a fan of drilling the other oil galley plug (0.020”) on the passenger side for timing chain lube, however that is a tad over-sexed as well. Modern timing chains are very tough and it takes a very long time to stretch one out even just with splash lube. A buddy of mine recently cam swapped his 75K mile 393W where the Ford FMS-M-6268-A302 timing chain had only splash lube. There was some, but very little, noticeable stretch on the chain and no discernable wear on the gears. We changed the timing set anyway as its prudent for that job. Readers should not use an oil slinger with a dual chain as it will rub on the timing cover! Keep up the good work on your mods. I’m binge watching !
@@BlueOvalEdge I welcome your input! The mod was recommended by the machine shop that did the over bore and line hone. My dad also said it was a mod that he had run in the pst with success. Hopefully it pans out for me. Thank you for watching and commenting!
Thanks for commenting! You’re absolutely right. Check my newer videos. New shop, with LED lights. Thanks again for taking the time to comment. Means a lot
I ended up having piston to valve clearance issues and it turned into a series on how to clearance pistons. I have a playlist with all the engine related videos on it. Thanks for watching and commenting!
@@rdspeedfab....Most new SB Ford camshafts come with a choice of two pins, a long and a short. The short one you installed first was for use with a 2-peice fuel pump eccentric. The 1-piece eccentric you had laying on your bench uses the long pin....and just as a FWIW, the 1-piece eccentric is not actually for use with a mechanical pump, it's merely a counterweight that Ford used on many of their EFI engines.....hope this helped.
Very detailed! Great video! Thanks a lot for uploading.

This volume is a LOT better. Thanks!
Alan Hardman I’ll look at the settings on this video and match them for the future. Sorry about the troubles!
Where did you get the galley plug with the oil hole in it?? Did you drill it your self? Is it necessary?
It’s not necessary. My machine shop drilled the hole for me.
had Piltcher build my 572 for my fox.... you live around dothan or Rucker?
I did when I had the machine work done. I was working at Rucker. Moved up north now. North of Birmingham
Why didn't you degree in your cam ?
I have since this video. Check newer videos on this engine build. Thank you for taking the time to watch and comment!
You need some l.e.d. overhead lights

What are the size of those plugs?
Which plug?
@@rdspeedfab the front cam plugs
