What cam?

-
If you get a used cam, is it highly advisable to buy new lifters. That kinda moots some of the point of buying used. Don't be stupid. Buy a new cam.
 
Hey Guys:

I'm trying to get my 64 Valiant back on the road, and while I got it running I'm wanting to do a few upgrades. Lets start with what I've got, a 64 Valiant 2 door post factory V-8 car that had the 273 replaced with a stock 318 about 20 years ago and has set for the last 15. It has a stock 904 push button trans and stock rear-end (not sure on the ratio yet). The intake is a Elderbrock performer with a 600 Holley setting on it. I recently purchased a set of TTI Headers which still have to be installed which will include duel exhaust. I'm also looking into a MSD distributor system for it. I have no idea how to select a cam, but what I want is a nice street cam that does not require me to do anything with the rear gears or run a stall converter. Just something to wake it up a little.

Any advise is great appreciated.

Jon Williams,

We Need To Know,


Rear-End Gear Ratio > 2.76 ~ 2.94 ~ 3.23
Rear Tire Size >

Most likely, you have an 'Hydraulic' Camshaft in the 318 now.

* Do you plan on having a Valve Job performed on the Cylinder Heads ?

* Or, do you just want to swap out the Camshaft ?

Seeing what you have and want.

You should look for a Camshaft with the following profile >
Lift ................................ .430" to .455"
Advertised Duration .......... 260* to 270*
Duration @ .050" Lift ........ 210* to 220*
LSA {Lobe Separation} ..... 112*

Lots of 'Bumpsticks' in that range to choose from.

Crane Cams 'Powermax' {Grind H-260-2} Part #693902
Lift ........................... .427"/.454"
Duration ..................... 260*/272*
Duration @ .050" Lift .... 204*/216*
LSA {Lobe Separation} .. 112*

A very good Camshaft for the {1500 to 4500} RPM Range.

And the kit comes with Anti Pump-Up Lifters.

Cost ..... $246.30 .............. You Get What You Pay Before

If it were my car the first 2 things I'd be doing to wake it up would be gears and a convertor. That will have vastly more performance gain than a small cam change.

If you're set on a cam. Here is my recommendation.
Comp Cams #20-246-4

Gee, looks like Rusty's cam choice would be perfect. Still un-noticed.

IF,

That Valiant has 2.76 or 2.94 Gears in that Rear, that #265-DEH Camshaft will be a
sacrificing a lot of Low-End with a Low-Compression 318.

I have a 2.76 in my Swinger. I think the 3.23 Sure Grip I have waiting in the wings will be a nice improvement without sacrificing highway mileage.
 
Sounds like a no brainier great choice RRR, I am sold could you tell me part # for springs,and can i use the stock retainers.
 
Break the cam in with your old springs, then swap in the new ones. Make sure you coat the lobes and bottom surface of the lifters with the moly grease that the cam comes with.

Sorry, I disagree. Install the new springs on the head to be used and break it in with the new cam. There is no issue in doing this. The way you suggest is just more work that is not needed. The old springs may not have what is needed to do the job right and once.

The cam is small and doesn't need to be babied or large enough for break in with half the spring set up.
