DZ 302 Main bolt kit

Does GM make a complete main cap bolt kit with the correct studs for the windage tray? I'd like to use standard bolts and the correct 5 studs. I had a set but sold it with a motor, now I need to replace it for a new engine project. The parts book shows parts individually, but on gmpartsdirect.com, they do not show up. ARP has a full stud kit, but I do not know if it will fit the stock tray and pan without tray mods. They also show a bolt kit, but make no mention of studs for the tray. Can someone help? Thanks!!

Re: DZ 302 Main bolt kit

This is the only PN from GM. These studs are for '68 and later blocks, designed for use with the PN3927135 windage tray and PN465220 Z28 pan, and are sold individually.

Re: DZ 302 Main bolt kit

My mistake. My GMPP catalog shows 3927136 as the windage tray that works with the Z28 pan. I also looks like the Z28 pan PN was changed from 465220 to 360450. -Neil

Re: DZ 302 Main bolt kit

I've been meaning to ask, if you swap out the 5 stock bolts for the windage tray studs, is align-honing the mains ever necessary?

Re: DZ 302 Main bolt kit

3927136 is the number from way back, I have a GM counter parts catalog form 1977 and it's listed as that. The pan for z/28 was 360009 back in the day. This pan and baffle was used on 1967 -69 302's and 70-75 350 with spec hi perf (z28 and Vette)

Smile Re: DZ 302 Main bolt kit

I found the info on SB windage trays!!

The early flat tray, PN 3769768 is listed as the 'Vette small crank journal block tray and it uses (5) bolts PN 3872718.

PN 3927136 is the '68 and later Z-28 curved tray along with (5) slightly longer bolts, PN 3960312.

I had the early one in my junk 301.

Re: DZ 302 Main bolt kit

Thanks to all for a bit of mystery unravelling....I will continue to look for the balance of the part numbers, nuts, etc. As far as the line-honing, it's always a good idea, but not always necessary. Some posts I have seen say if you use main studs to hold all the caps, line-honing is a good thing for sure. Check the ARP web site. www. arp-bolts.com This holds more info on that product, I believe. Also, do a search here. Lot's of good info. By the way, the stud part number is 14087508, it was 396012 for 68 and up. www.sdpc.com is also helpful. Thanks again,

Chuck D.

Re: DZ 302 Main bolt kit

PDQ don't you wish you had that small journal setup today? One bolt costs as much as a set of five for the medium journal setup.

Just curious what are guys doing with the larger journal 400 blocks when adding a windage tray? Looks like aftermarket is the only way to go unless it's possible to slightly open up the holes on the GM tray?

Question Re: DZ 302 Main bolt kit

Yes I do. I put all my crap out in my buddy, Scrouge's barn out in the country around Higbee, MO back in about the summer of '74 when I had to move to Ft. Madison, IA to work at W.A. Schaeffer Pen Co.

Let's see if I can remember what I squirreled away??

A Tri-5 cast-iron B/H, the other half of my 6-banger Fenton header, my in pieces complete junk 301, heads, heads, heads..

A guy "stole" my other trip setup that was off of either a latter, '50's, Cad, J-2 Olds or Pontiac, I never did know which one?? I still have my other three matching trip carb's in my car now but no intake and I still don't know what they were off of but do remember both sets were different??

My Olds and Buick, 215" aluminum V-8's, etc....

I need to go up there onna these days and see if its still under the barn??
