Cam Install ?

[dapack69]

I already have ported heads, Can I change the cam with the heads on? Or should I just take the heads off.

you dont have to pull the heads. At least you didnt on my old 350. just pull the intakes and losen the rockers, unseat all the push tubes, and the cam should come out with no problems.

What about upgrading the springs at the same time. I heard something about putting nylon string in the cylinder

[el cheapo]

uhh, i dont know anything about that. I was under the impression that you had to pull the heads to change the springs. (Ive never done that)

Ill be doing a cam swap in a few weeks.

The way Im swapping springs is using an air compressor adaptor that screws into the sprak plug holes. Put ~150psi into it constatly, and it should keep the valve up. There will also be enough force holding the valve up that the amount of force needed to compress the springs wont even be close ot moving the valve.

I talked to a mechanic friend about this and he said that is how you swap springs with th eheads on.

YOu dont have to take the heads off when you change the cam. Its just a whole lot eaiser.

WHoa~~~
If you don't pull the lifters, won't they block the lobes of the cam from lifter #1 when the stock cam comes out?
I know there is a good roller timing set out there somewhere, Morana maybe? Great time to swap out the timing chain when you're in the motor that far huh? Does someone make a better lifter too?
WHo's put in a new cam and got better power N/A? First things first ya know....;.
