take the time and degree that cam

[grumpyvette]

now if your like most guys if youve never done it your thinking it a huge complicated deal, ITS NOT,just follow the instructions in the links, Id advise you read them all because some are more clear on some parts of the process than others and youll get a better over/all feel for the process. all you need is a degree wheel, a dial indicator , a solid lifter and a pocket calculator and its something you can do in about 15 minutes time.

 

NOW youll be asking WHY BOTHER?

well its RARE for the index marks on the timing gears and the cam index pin to place the cam lobe rotation EXACTLY where it was intended to be and a shift of only a few degrees can and does move the power curve a hundred or more rpm up or down in the rpm range. now thats not huge but in a few cases youll find the cams significantly differant than the specs indicate and you could easily be down 5-20hp or have it idle like crap, if its indexed wrong, Id be very surprised if some guys cars ran worth a crap or at all if you just slapped in useing the cam gear index marks.

and in one case I found the cam gear in a imported timing sets chain drive to be off almost 9 degrees, if you had installed that IM sure the car would run like crap, that cam gear was manufactured in INDIA and it was purchased at discount auto about 10 years ago, so there ARE crap parts out there in the market place.

BTW alot of cam drive gear sets come with 3 crank slots and 3 marks on the cam timing gears that need to match to index the cam and if you screw it up durring the install is possiable to totally screw up the relationship between the cam and crank, degreeing in the cam points that mistake out vividly

 

youll need a few basic tools and a good understanding of what your doing, but its certainly not all that difficult.

 

I was asked where to get a CHEAP degree wheel

BTW you CAN advance or retard the roller timing chain its done bye drilling out the cam index pin hole in the timing gear and installing an off set bushing

you could buy these from summit racing or similar parts from jegs

 

this is 180 degrees out (the distrib rotor points at cylinder #6, so before you drop in the distrib rotate the crank 360 degrees bring both marks to the 12 o-clock location, then drop in the distrib pointing to cylinder #1, and adjust ignition timing from that point

remember the KEY to having a nice car is NOT wasting money, having a high power to weight ratio , plus good suspension and brakes and knowing exactly what your trying to do, then doing it correctly,and doing it safely

most of the guys on this (Z) site will help you with info,and keep in mind that since they are generally doing more extensive mods with aftermarket parts and engine swaps ETC. they are the true hot rodders, are usually forced into thinking things thru, rather than the parts swappers on most sites
