First cam swap questions.

[acelondon]

Hey everybody!

Quick question:

Can i drop a 340 cam in my 318 without changing anything else? I'll drop in a new chain while im in there.

Also, What all do i have to do to get the cam out?  Clearly, water pump, timing cover, distributor. But is there a bolt on the back of the block, or anything of the such, holding the cam in?

Thanks

Wait to see if some others pipe in.  There are plenty with more expertise on this than me.  I swapped a cam in a 383 and you can see some of the issued I ran into here

Only a bolt in the front for mine.  There is a plug in the back.  I just looked at my copy of the factory service manual, and that has a reasonable description to follow.  But again, I suggest waiting for others with more experience to offer their advice.

Depending on which cam you decide to use ; there might be a need to install a different valve spring. Bigger cams with higher lift and more agressive lobes need increased pressure and must not go into coil bind.

It's a bone stock 340 cam repo by Comp.

There's a big difference between a 318 2bbl cam and a 340 4bbl cam. I would check with Comp for a valvespring recommendation.

Considering the stock cam floats the valves around 4200 rpm, i think that's good advice! Thanks!
