Guy finally emailed me back, and he sold the pulleys. One question i didnt ask, would any of the pulleys off the 318 poly work?

There's a set on eBay for $95 shipped with a best offer option so yo may be able to get them cheaper. The only pulley on your 318 that'll work is the alternator. You can have my spare set of alternator brackets, pm me your address and I'll ship them out. Then you'll just need the pivot bolt/spacer set.

You could get a 3/8" bolt of the right length (coarse threads) & I'd suggest a grade 8 and likely at a hardware store you could find something to slip on the bolt for a spacer then cutdown/adj the spacer length as needed when you mock up. I'll post some pulley pics later

It would be cheaper to find a used set than what they want for pulleys.I paid lee for my March Ubderdrives.I have a set in the old garage somewhere.Havent seen them in at least 15 years though.Like I said I ran the AC lower 4 groove with the single wp pulley.It was on for 30 years and had no problems.Rocky

BB pulleys. not sure what year or if AC or not. Dimentions posted earlier

RR they arent AC.AC has 4 groove lower and usually a small wo pulley.Those look like plain lower no Ps and upper looks like dual for alt.Rocky

Yeah I spaced that that the AC is going to have the 4 crank grooves & the small WP pulley. These in the pic came from my buddys estate & he was exclusively a BB guy. I could swore I posted the dimentions of these yesterday but I dont see it in this thread so I will remeasure tomorrow as I tossed the scrap of paper I wrote it on as I thought I posted it. While looking for it I did find a prior unrelated note from way back that states The WP pulley is 5&7/8 for AC and 6&7/8 for no AC and the crank pulley is 6&1/2" with no AC and no PS. EDIT found em! I had posted them on the other pulley thread. 2 black pulleys in my pic (measured by me) they are WP 6&1/2" and 2&5/8". Crank: 6&3/16 dia & 1&3/4 total depth. which does not match what I have in that old note

I know when I ran the factory 4 bottom pulley on my 440 I had to tilt the WP pulley into place for it to fit.I dont have ps or AC so all I used was one belt for Alt.That 440 was from a New yorker that had AC.I thne went March underdrive.The kids 62 I think had 2 lower grooves.One for alt one for PS.He went March also.Rocky

Thanks pynzo, will do. Have a couple places here i can get a grade 8 bolt, and may have something i can build a spacer out of.

Rocky what do you mean by March? Fyi, i have ps.

You'll need a 6" bolt. Grade 5 or 8. The longest spacer you already have, it's in the middle of the alternator setup on your 318.

We run March Under drive pulleys.I got mine like new for 50 bucks.My kid bought his at Summit clearance for like 75 bucks.Lots of guys say they make it run hot but both our BBS run 180 all day long.Look at 440 Source web site.IIRC they sell used factory pulleys.I know I have at least 1 set but I havent seen them in at least 15 years.68 should have a single belt to alt and a belt right from bottom pulley to the PS.Rocky
