With my World block i seem to have a resonance causing the pan bolts to loosen up , even with loctite
i have been using the standard Felpro , but very thin and dont seem to like retightening too often . I have used a Milodon before and like the look of it bit thicker . I currently have a Felpro 1834 to try , its a steel core type and uses a silicon material (?) . Felpro says NO sealant . It is thick and notes as being for KB top fuel . I think i read somewhere NHRA mandates this style .
Its a pain to pull the road/race pan so it may wait a little while . Have to trim lower trans bell a little to help.
Noone here in Aus carries Superformance , still wating for Mancini on my last order . Better call Todd .
