hi. does ARP make a stainless intake manifold bolt set for the 455, and can anybody help with the part number? thanks, jim
Hello. Someone keeps on running an e-bay ad for stainless intake bolts for a Buick 455. Here it is<<http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33620&item=2449214356>> Here is another one.. <<http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33620&item=2448399481>> FYI
I am using ARP black oxide intake bolts, looking at thier website they do not list a 455 aplication so they must just happen to be the same as another application. I thought i bought them from TA a long time ago.
I think what it is, is that ARP makes them exclusively for TA Performance. I bought mine from TA, and they do say ARP on them in fine print, and they do look good and don't gouge the aluminum. And it seems like there was a discussion about stainless a little while back, the thing I remember is that most stainless is not Grade 8. Might be worth doing a search.
Stainless is softer. It will snap if over torqued and will probably expand more than a moly bolt when heat is introduced. I'm very leary of SS bolts that require a fair amount of torque.
TA has GRADE 8 equivelant stainless intake bolts for 455's. We also have them for the timing cover/water pump and exhaust manifolds. Like mentioned, regular stainless is softer, do not use standard stainless hardware or it will twist when torqued. Here is a link. http://www.taperformance.com/boltkits.htm Dave
