here is my question. are these cams going to be too big for my setup? i know that they are supposed to make more power up top but does that mean that i am going to lose it down low? also i am most likely doing new springs and retainers just fyi. i stumbled upon a set that a guy is selliong for cheap

CROWER CAM 63403

 

il sell ya my blox type c cams for 300 there basically brand new used for about 400 miles and now im going back to stock need a reliably DD . it is recommended to upgrade springs and retainers but strongly suggested to use stock valves

and to answer your question i doubt you would lose any down low power if you did it would be so little you wouldnt even notice, but you would notice a gain through the mid-high rpm range

 

well i came across these for 170 lol

 

if they art the same as the original crower stg III (63413) they will fit but be close for the pric i would buy them and clay the motor.

 

how tight of clearence are we talking? cause i still have to deck my head

 

also these are 63403

 

403s would be crower, not brian crower (not the same company)

 

hmmmmm ok i didnt realize the 403s werent BC. ok well then has anybody ran these or have an opinion

 

crower stage 3 cams are 63413 BIG lobes and i forget the clearance but i do remember i did +6 on intake and -6 on exhaust

 

i have done a bunch of research on them and back in the day everybody had problems with them breaking. now i dont know if they still have breakage problems but i am a bit worried. so does anybody know if this problem has gone away?
