putting stock camshaft back in and taking out crowers read

[supraking16]

i have crowers 264 and they will not run right so i have got fed up with it but i have a question i have two motors i took the head off the motor in the car that now has the new head and cams but i want to put the stock camshafts back in the head on it should i need to worry about journal wear. the specss are all the same area and i have crower springs that shouldn't hurt the stockers and well i want your opinion on this

.... What?

.... What?

Agreed. Try using some punctuation to form proper sentences. You'll probably get a lot more attention when the folks reading your post don't feel like they need a decoder ring.

You're worried that taking out the crower camshafts and putting in the stock camshafts is not possible, because of how the journals have worn?

I wouldn't slap them right in, I'd wait for someone to comment on if/how to measure/clean them up.

They "Should" just drop right in. But you will have to adjust valve lash. Springs will be fine too.

should be as simple as remove, replace, plasti gauge, shim and drive away. well maybe not simple but shouldn't be to hard. just remember to plasti gauge the camshaft caps and compare specs to the TSRM,

plasti gauge? huh?

Why won't it run right.....Do you have a aftermarket ECU, Did you degree them in What are the cams not doing. My Crower cams work fine....I got the first batch and never had a problem. Tuning is the key and I have 272 cams tuned to idle at 890-950 max standing idle no lope. Some of you have no idea how to tune a motor.

 

[Devin LeBlanc]

He did not degree them, Needs to use a degree wheel and dial indicator and they will run excellent.

Booskyline: what do you use the plasti gauge for when installing cams and shimming?

 

[89nasupra]

You use plastigauge to check journal clearances. Want to make sure the journals are not warn out to much to where it will damage the cams and the rest of the motor beacuse the oil is not staying where it needs to be.

Well, i had a break though on it today I installed an AEM AFR gauge and its running rich. It is all the way rich after it warms up but a little rich when it's warming up. why is it running rich i didn't do anything else to it could the cam shafts cause this. And thanks for all the comments

 

[bioskyline]

what 89nasupra said. the more its squished the tighter the clearance.

 

[supraking16]

he was talking about a plastigauge. u put it around the cam shaft jurnals and put the cap on tighten then take it off and check how much it squished it and then u will know if the clearance is right or not little more to it then that but that's pretty much it

 

[Devin LeBlanc]

I thought you were talking about using it for valve lash and shimming, You could mic the journals too

Plastigage takes about a minute. Much easier to do than to mic th journals. Make sure when you do this you don't have the liming belt on also. It could give false readings.

Were talking about stock cams going in. Stock cams should fit. Bc cams should fit. If you have wear damage then its time for a new head.

Since he did not tune the cams he is removing them. Valve lash is in order.

Plastigauge is easy to use but a time consuming pain.

 

[supraking16]

i had a machine shop rebuild the head and install the cams in it i just put the head on but didn't know anything about degreeing them until afterward but i think i have some other problem.

 

[Devin LeBlanc]

We have had crower cams off 30 degree's on the race car they need to be degree'd that is where your problem is probably if you didn't

 

[hvyman]

Exactly there is more than just slapping them in to use them Now that you want to go back to stock there is more than just that.

The machine shop should have not line bored the cam journals, so they stock cams should fit. Im not the person installing them and looking at it so im not going to say for certainty and im not taking any blame for mis haps.
