I just purchased some Crower cams, i was told they were LS camshafts and that they were 403's, now im starting to doubt it because no where on the Cam's do they say "403". One cam does say crower, well it says "rower" not the whole word, on the ends of the cams one says "L28646" and the other cam says "E28646", the camshaft with the L on the end also has a MV and a Z or a N in between the cam profile. The E cam has an E stamped in between the cam profile. I know they are not stock becasue of the crower markings and because they have alot larger cam profile and the lobes are a bit differnt in design, so any one know what camshafts i have? thanks in advance for any input...oh and i did contact Crower i got no where the numbers are different then those provided on the site, and i emailed them and i havent gotten a response yet, so anyone got an idea?

pics??

 

i havent had eought time, if i take pics what should i take pics of??

 

anyone??

 

bump, i just got a hold of a digi cam what should i take pics of??

 

take pictures of the distributor side of the cams. not the side of where the cam gears go but the other side.

right on the ends the grind part number should be engraved into it.

 

e-mail me at lodoss@cavtel.net and i'll let you know if they are 403's are not cause i got a pair sitting in my room at my house. I'll look at the number when i get off of work.

I doubt they guy lied to you cause clearly it is made by crower and if it is made by crower there is no reason why he would tell u 403's if they were 401's cause price wise they are essentailly the same.

 

it should say Crower on both cams and the number should be 6xxx403. Mines are 6xxx404 because I have the 404s.

 

its says crower but it dosnt have those number, il have pics up soon...

 

here are some pics that i took i had to modify some cuz they were dark, but here they are

Both cams


C"rowe"r


Weird mark


"BY" mark


so anyone have an idea of what cams i got, or should i take diff angle pics?

 

anyone?

 

picture bump

 

those pics suck.........hehe........find a better digital camera.

the first pic is the one i want to see clearly. there should be gring part number engraved on those ends.

i should mention that crower did re-grind stock cores before they came out with new solid cores a few years ago. so those may be crower cams but they could possibly be one of their original re-grind versions.

hope this helps

 

one says "L28646" and the other cam says "E28646". Thats what the ends of the cams say....

 

send crower a e-mail with those numbers and as them.

they should be able to tell you what they are............

 

Those look absolutely NOTHING like the 403 cams I've had before. The CROWER stamp were very clear and clean and had the complete name on it.

 

i think they might be re-grinds, i already emailed them, i gues its time to email again and call...

 

bump for anyone that might know

 

i finally found out what size they are, they are beast's

"BIG RACE ONLY CAMS W / REDUCED BASE CIRCLE SIZE FOR LONGER VALVES."

INT 254 / 503
EXT 250 / 503

 

anyone have a crazy allmotor LS setup that needs some cams??

 

I might be looking, and if not me I have a friend doing an all motor b20. How much you lookin to sell em for?

They sound a lot like the 405's btw

 

well on price im not sure im not set opne one, i would rather trade them for something i need, or i will sell at a good offer..and ya the guy at crower told me that they were almost worthless for a street setup...just DRAG or some one with a crazy street car..

 

Pm's sent

 

That's insane! Any other modifications needed besides dual valvesprings to make this babies work?

 

for some reason i thought .502 lift was max.

anyway these crower 405a's i have sitting here are

.280/.478
.274/.469

anyway those cams might have some clearance issues in the head/ and will definately require upgraded valvetrain/ and some sort of ecu mod, SAFC, better yet, hondata.
