Hey guys I have a 1989 302 5.0 engine and I really need to know what type of bolts go into the upper intake, like can someone give my specs on them because I have literal look every where can not find them, hope you guys can help thank.

 

If you mean the upper to lower they are 5/16"-18. Lengths will vary depending on intake and whether or not a spacer is used.

Ive got 3" studs in mine and around a 8" bolt on the center left hole. Ive got a TFS R-Series intake with 1" spacer.
