who has done a cam swap in a 2F without removing the motor???

[Mace]

Thinking of doing a cam swap in my 40. The stock cam dies at 3500 RPM. I want more...

I have to take the rig down to fix the turbo. How hard is it to swap the cam at the same time?

loosen the rockers
Pull the pushrods,
Try to pry out the lifters?? That is my main concern, how much of a PITA is this with the motor in the truck??

I am not going to replace the cam bearings..

The best way to get the lifters out is to bar the engine over till one(each) comes to the top and grab it with channel-locks..... other that what you said.. the dizzy, fuel pump, radiator, front cover and cam retaining bolts, then lay the bib over and pull it like a bad tooth.......

Cam

Don't forget to grind the old lifters or buy new ones.

Forgot about the lifters...

Anyone hand grind the stock lifters? Technique?

got any pics of the turbo set up Sparky?

Mace, I could not get a price of less than $5@ to grind lifters. 12 x $5 =$60
For a hundy, you can buy new Japoneeze lifters.............did not seem like a real decision to me, given what I had already spent. Now you have more machining equipment than I have/had access to. You also have more skilz than I do(really), but factor in your time and the probability of a good result and you may be better off with new....

to pull the lifter jason, why not use a good heavy magnet thru the side cover?

 

[Mace]

I have pulled lifters through the side cover before. They can be amazingly sticky..

magnet will be first..

Gotta go hit Harbor freight for an aluminum pair of pliers..

do you have any spark plug wire pullers?

 

[Mace]

just looking at a set at HF...

they also have some neat pipe pliers.
But they only go down to 1 1/8"

Time to find a cam

All I have to say is good luck

Removing a cam inframe is no big deal bud....


Good, strong magnet will pull the followers most, if not all the way out of their bores.

You should not need pliers. They will move/rotate in their bores. When they are loose, just lift strait up.

Figured, just never did it in the truck

so cam specs of 262 (advertised) duration, .442 lift


Any difference because of the turbo?

Out of my league here with this bud, sorry.



Mark W or some of the other far more experienced folks out here will chime in.....


Didn’t the whole camshaft conversation occur in the 2F thread in the FAQ? It has been a while since I went through that, but I thought someone was having a custom cam ground for higher RPM power???




Please take some pictures of this Jason.

I am actually gonna call Isky Cams in the morning (or monday) and see what they have to say.
Turbo cams typically have different exhaust and intake profiles..

Chances are I'll send them a cam to regrind from their experience..

I also have to figure out if I want to find someone to reproduce the adapter that allows the T04 to bolt to the factory exhaust manifold..

What does it need to be made out of?


JPL-type s***, or average ass-hole stuff?

 

[Mace]

NASA is not needed

Cast Iron/Steel most likely Ass hole type s*** defines me .

It is a simple adapter. Which is one of the reasons I like it..

The question is, is it worth it...

Got any general pictures out here?
