anyone know if these are for a ls1 arp 230-7001, ive been looking for way to long now for bolts, are these it or anyone know who make the bolts so i can order em

 

These bolts are M8 x 1.25 x 28mm. I used ARP 661-1002 which is a bulk pack of 5 each hex black oxide M8 x 1.25 x 25mm.

ARP 230-7001 is for a Gen I SBC and won't fit an LSx engine.

 

i come up with these with that part number

ARP-661-1002 ARP Chromemoly Bolt Kits
Bolts, Hex Head, 8740 Chromemoly, Black Oxide, 6mm x 1.0 Pitch, 25mm UHL, Set of 5

maybe its a 671

ARP-671-1002 Bolts, 12-Point, 8740 Chromemoly, Black Oxide, 8mm x 1.25 Pitch, 25mm UHL, Set of 5

want to make sure before i order those

 

Look here: http://www.arp-bolts.com/Catalog/Catalog.html
Page 81.

661-1002 is a standard 6 pt black oxide M8x1.25x25mm
671-1002 is a 12 pt black oxide M8x1.25x25mm

Either will work, but the 6 pt are typically a little cheaper.

 

I went to autozone and bought stanless steel 6pt. 10.9 rated bolts for mine. The torque for those bolts is only 18 ft. lbs. as is most of the M8 bolts on an LSx engine

 

great thanks for the help guys
