most use the suds but the factory used bolts not studs. Just measure for size and use grade 5 or 8 and as you said anti seize.
Greg's Stainless kit shows : All Buick 400 430 455 with following casting numbers. Passenger side 1383648 and 1238094 Driver side 1233451, 1233899, 1246671 and 1383549 I am trying to locate the ramp locks for '68 BB. Without knowing my casting numbers. Any suggestions ? DL
Hey thanks for the help David. If all else fails, I'll get his kit. It said it comes with a bolt length instructions sheet DL
"The www.Falconparts.com kit #code-3476 looks like ....." See post #1 supra. For the AMK numbers see post #10 supra.
I should have every bolt you need, mostly originals or AMK's. Once you get your manifolds, bring them over and let's take a look.
I am using the AMK bolts, except for the 4" bolt, and want to know, what are people using to keep the bolts from rusting once installed? I am currently using high heat flat black paint. Has anyone thought of using black jet hot coating to protect the heads of the bolts, and then chasing the threads prior to installation so the bolts go in correctly? I know, us concours geeks are insane about our bolts. Only on the V8 board do I get to share this type of conversation with others who share my affliction. Thanks, Ken
Ken a coat of anti seize would keep the rust off the threads but heads are another story. I am going to try and coat with the Slip Plate that I am using on the manifolds. It is a graphite coating not a paint so it should last.
guess I'll go with the Falconparts kit for my '76 455, as I could not find those AMK numbers on their site
Buick Nut check again. www.amkproducts.com they are on page 109. You need several different sizes. The Falcon kit may only have one size. Not too sure about that kit. Read entries above for lenghts.
okey dokey I found 'em....... their prices aren't too bad either. so that will get me the bolts I need for my '76 455, except for that 4 inch bugger.:rant: I can't weld, so, I may try and save the original 4 incher ray:
Boy were you right Dave, I asked him what sizes were included in the kit code-3476( because it does not say) and his reply was WHY ? what jerks. I sure am glad Buick guys are nothing like that. Fortunately, someone helped me with the 4" bolt I needed. DL
I guess calling them is a waste of time then. Thanks for letting us know Don't want to spend money with jerks anyway. They must think the economy is good or something.
I was just looking for replacement bolts for my Nailhead...3/8" x 1" with the ramp washers. I couldn't find anything to match at Carlisle, so I bought some indented head ss bolts from Totally Stainless....$13 for 16 with the plain lock washers. I bet they could repo the ramp washers if there was enough interest. The ss bolts look nice, but not concourse nice...still a good deal for $13.:bglasses:
The exact ramp lock bolts like NOS at least fo the 455 are available from www.amkproducts.com. That is what I am going to use. Only the long 4" bolt is not available. I cannot speak for the nailhead because I ma ignorant of it but you should check them out.
Then and Now has them. I picked up a set last week. He had them at the Nationals last year, and I'm sure he will have them there this year. They are the correct bolts and the original style locking washers, but they do not offer the long passenger side bolt. But they have you covered for all of the others. Give Mark a shout on his forum here.
HEY WHATS THE DEAL FOR US 350 GUYS....ANY INFO ON THE 72 350 EXHAUST BOLTS????????? JUST BROKE OFF ABOUR 4 OF THEM TAKING THE MANIFOLDS OFF ou: ...LOL BUT THEY DIDNT LOOK TO BE THE ORIGINALS ANYWAY
Same for me... Are the 455 bolts similar to the 350 bolts? It must be a similar design to hold a similar heat shield right? FYI - In the help section at autozone, I found a set of exhaust manifold bolts that look like the original design that would also hold the shield, but I have not tried them (still in the package). They do say for early 90's GM so I have my fingers crossed when the time comes for me to go back to manifolds instead of headers.
