Wrong. The old bolts are rusted/mismatched/vise-gripped, etc....
If someone has a rundown on correct grade/size/length's of bolts for bellhousing to motor, and intake-exhaust manifold to engine, I'd really appreciate it. Or a source for a bolt kit? Steel, not stainless, polished, etc.... plain old bolts, like chevy used.
Thanks folks

The manifold bolts are 3/8 coarse thread. Use your old bolts for the length. I like grade 8 bolts. The Ace hardware store I use has a great selection of grade 8 fasteners. They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | |
