i was wondering what size and diamater hardened pushrods i should be running with this cam? 224/224 114* .578" lift.
some 7.4?s>?

 

if it has an .030 smaller than stock base circle you need the hardened 7.425's

 

im guessing thats a thunder racing cam??? if so 7.4 or 7.425 will work fine

 

if it's a thunder they usually use comp i think so it's .030 smaller needing a 7.425

a 7.400 on a .030 smaller base circle will give you bad valvetrain slapping noises

not sure what kind it is but I'm running a comp 224/224 on a 112 lsa and I have 7.4 pushrods and personally I think my valvetrain is quiet as hell.

 

if heads are not milled 7.4. Milled heads than 7.35

 

this is the same cam i have.....



exactly what i run....


i dont have any valvetrain slapping noises..


this cam pulls real nice from 3000rpm and up...i need to get my TC in so i can really see how well it performs. You will need a tunr though, it runs like without it....
