Sam (Bones) Posted February 9, 2009 Posted February 9, 2009 OK people... you have showed this before, I want to replace my March alternator brackets, I keep throwing belts, yes I have the deep pulley. I have seen some low and mid mounts (stock location now) what do you people have???? I think Scott Heck & Greg have showed them before
72MC Posted February 9, 2009 Posted February 9, 2009 I have CSR low mount brackets for the alternator. Power steering is also CSR. - Dave
Shadow Gray SS Posted February 9, 2009 Posted February 9, 2009 I have a Billet Specialties part #135-FM2221PC on my truck. No problems with belts yet. Here is a pic from the front
monte70car Posted February 9, 2009 Posted February 9, 2009 Here is the setup on the Monte Sam it is a march setup. . The El Camino also runs a march setup but uses a sep belt
montecrazy1971 Posted February 9, 2009 Posted February 9, 2009 Sam this is the system I have Mike57 also was throwing belts and went with this system.
Sam (Bones) Posted February 9, 2009 Author Posted February 9, 2009 that's what I'm looking for but for a standard belt, and I don't need billet either, just want it to keep the belt put @ 7000 RPM

Sam (Bones) Posted February 9, 2009 Author Posted February 9, 2009 I'm looking for a mid mount for the alt I think Scott Heck has the one I'm thinking of I'm not throwing the belt until about 6000+ RPM, I have put a smaller crank pulley on it to slow down the alternator, haven't got to run it yet, and I hate that smaller pulley, cooling/charging issues with it, was just hoping to get different brackets without having to spend a small fortune, I still want that 8" Coan converter
Chevyss Posted February 9, 2009 Posted February 9, 2009 Can't see winding a big block to 7000 grand. The BB that I have, they say nothing over 6000 grand. How is the BB built to go 7000 grand?
Sam (Bones) Posted February 9, 2009 Author Posted February 9, 2009 probably cause you have stock rods I have a Scat forged crank,6.385 eagle h beam rods, JE forged pistons, and a huge solid roller cam, all balanced out to perfection, doing a burnout it SNAPS to 7000 in a blink of a eye, you can hear it if you click on the burnout video below
Mike 57 Posted February 9, 2009 Posted February 9, 2009 I have the march bbc serp system I tried to stay with V belts but no luck. I have had my big block to about 7100, basically the same bottom as sams with a good balance. If your machine shop told you not to go over 6000 you probably have 3/8 rod bolts. Good factory big block rods had 7/16 boron rod bolts and were very heavy on the big end of the rod.
Heckeng Posted February 9, 2009 Posted February 9, 2009 Hey Sam, sorry it took me so long! Here is my bracket setup, it is the mid-mount from Allen Grove. Moving it lower to the mid-mount setup does make the belt shorter which might help to not throw it--just my guess. Mine will hold the belt on up to 6400, but I can't say what would happen if mine went to 7k! I would assume the belt might stay on, but my rods would probably land on the moon!

John Burns Posted February 10, 2009 Posted February 10, 2009 Does anyone sell stock-style serpentine pulleys that will directly replace v-belt pulleys? I'd like to keep all my mounting brackets stock and still use my clutch fan. I'm not interested in billet- stamped steel would be fine!
waupachino Posted February 13, 2009 Posted February 13, 2009 I shift my 496 at 6750 and has seen above 7K before not problem. With a full Roller set up and 2 stages of Nitrous it spins up there quick. I am running the Moroso deep grove pulley with the Alternator in the stock location and it doesn't throw the belt. Here is a Link. http://store.summitracing.com/partdetail...mp;autoview=sku
Ian Posted February 15, 2009 Posted February 15, 2009 I guess you would not throw the belt with those on there.
Heckeng Posted February 15, 2009 Posted February 15, 2009 Holy cow! Those are some of the coolest things I've seen in a long time! I wish they could make a set that included power steering though!
502ci Posted February 15, 2009 Posted February 15, 2009 I never seen that before.. Although that was at a high idle I would have liked to seen it revved up to at least 6000. Bill
Ian Posted February 15, 2009 Posted February 15, 2009 Holy cow! Those are some of the coolest things I've seen in a long time! I wish they could make a set that included power steering though! If you check out the website, they have a version that includes a pulley for the power steering..
wallaby Posted February 15, 2009 Posted February 15, 2009 It looks as if they don't have a power steering version for us "long water pump" folks. Getting back to topic, my parts book from 1971 shows a "reduced diameter crank pulley with deep groove". Chevrolet PN3899660
