What 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
