Ok i got the new camshaft installed everything is all setup the way it should be . i didnt centre the lobes or what ever. a friend of mine is saying is My gear Drive? and i need to get a chain? is that the problem? i dont even hear the CAm When it fires up he said . the Gear Drive has Slack So it is setting it off 2 Degreees. does that make a diff? let me know

A Friend said i dont have to Degree the cam. i got a 110 centre Lobe. will that make the car Run like Shit. i dont even here the Hear the cam when is Running its Running ruff. does that mean i have to Degree the cam?

There will be a small amount of slack in any cam drive system due to manufacturing tolerances and to allow for thermal expansion of the parts. There's nothing wrong with running a gear drive if it's set up properly. As a matter of fact, it will run longer without retarding the cam timing than a chain will because gears don't stretch like a chain. Most guys will run a gear drive for the noise because it's sounds like a blower belt and wows the geeks at the drive-in. There's also nothing wrong with running a chain, millions of them are in service at this very moment. You asked "is that the problem?" What problem are you talking about? You also said that you don't hear the cam on start-up. Do you mean that the motor doesn't lope? It probably won't lope with a 110 degree LDA. If you want lope, install a cam with 106 or 104 degree LDA.

You friend is right, you don't have to degree the cam. Again, millions of motors are in operation all over the world with cams that were not degreed-in.

Degreeing a cam is done for two reasons:
1. Quality assurance. How do you know that all the lobes have been ground at the proper position relative to each other and relative to the crank position? What if the cam grinder was having a bad day (hung-over on Monday) or the CNC computer developed a glich when it was grinding your cam and ground the intakes off the exhaust master or vice-versa.

2. Establishing a baseline. If you're going to maximize your cam timing in this motor, you need to know where you're starting from before you go advancing or retarding the cam so you can keep records of valve timing events and the results of your changes.

If you don't plan to make any changes after the motor is running, put the cam in on the factory timing marks and hope for the best.

When we installed the Cam we went top Dead Centre with The the Dots on The camshaft and Crank. something doesnt Sound right. when ya rev it it sounds Like its Farting! i got a lopey cam extreme Energy .477 .480 highest cam you can get with a stock stall its a comp CAM part # 12-242-2... so i Know it aint My gear Drive so thats out of the way. what are my other Options? taking the Front of the Motor of again>? and getting someone to Degree the caM? taking it to a mechanic and wasting my money? let me know thanx

Could It be The Roller Rocker Arms werent Adjusted Correctly?

What size engine?what carb? is there after market heads or pistons?

If this is a small block Chevy, you adjust your roller rockers just like conventional rockers. With the motor running, back off each one, one at a time until it clacks. Then tighten it down slowly until the clacking noise goes away, then give it another 1/2 turn. Do this and report back.

The Heads Have these Last Three Digits In it 882 so the motor has to be running to adjust them? What we did to set them Was Crank the Motor Till they had Full Lift. than we Gave em 8 between the rocker arms and The Springs and Made sure they were Snug

Adjust them like I said and report back.

Its a 355 Quad Carb The heads Im not sure but they have 882 the last the Digits of the Number Pistons im Not Sure Either. But something aint Right.

The oil Will shoot everwhere if it is Running Wnot it?

Get your self an old set of valve covers,,and cut the tops of them,,so you just have the sides,,,bolt them on and do your adjustments,,,it's a lot less messy.

So That is What my Problem is Ya think? cuz they aint Adjusted Right the Lifters arent sitting the way they should on the Cam?

That's a nifty Idea

Ok i got Them All adjusted. its Sounds a bit Better. i Think im gonna have to Adjust the the Lobe to 106 to get the Lump i wont. But i just took it for a boot around the Corner. Im still having the Same problem as Before No Power? just Reving Up what could that be? please Let mek now if it aint 1 problem its another.
