what's alleration ? :P

There are many cams for these engines, and it doesn't matter if they are 3.9 or 4.0 they are all interchangeable apart from the late EL motors. The cheapest ones being wade cams who have a good variety, the are $135 exchange, then you need shims. There is a sticky at the top of this section with a lot more info, so have a read through that.

If you're purchasing a Wade cam you need 1.9mm shims, which are available from Ford dealers for $5 each. Prior to buying them, you may want to get EF rocker gear as it's better made than those on the EA (so a cylinder head reconditioner tells me).

The shims fit behind the hydraulic adjusters on each rocker to compensate for the cam being reground.

only bother with a cam if you have a full exhaust and at minimum xh snorkel or it wont do much.

if its auto get a wade 1636 if its manual get a wade 977b.


wreckers will usually charge $4 for the entire set of 12 shims. EA-some eb2's run larger shims in diameter than later eb2-el(pre hybrid) but all are 1.9mm thick. you will need to take one shim out from you car just to make sure you have the right shims.

installing a cam is a pretty simple process, once youve done it a few times its about a 20-30 minute job.


also if you get a billet cam ($450 or so +) then you dont need to bother with shims. but the shims really arent much of a hassle and once shimmed theres no difference between a billet and a regrind.

also with wade cams you pay them $235 and get the new cam, then return your old standard one for a $100 refund.(or get another cam from the wreckers and give them that before hand if you dont have the extra $100 to outlay.)

My car has extractors, 2.5 exhaust system straight through (one centre muffler) and a cat converter from early 3.8 v6 holden.... it is a manual... and when it doesn't rain it will have an xh snorkel... so after chritsmas it should be ready for a basic cam so you suggest 977b cool

yes mate sounds alike a 977b is a perfect match for it. very good bang for buck. you notice a change in the power band right away as long as you adjust the timing to suit. also alot more torque which is very noticable you you hammer into 2nd gear.
