I have an '87 Chrysler 5th Ave. Yes, I realize this isn't an A-Body, but when it comes to spec'ing out a camshaft for the 318 small block, the rules apply to any Mopar body.
About the car:
Current Curb Weight - 3450 lbs
I removed a lot of
unnecessary weight and weighed it myself
Rear Axle Gear: 3.55
8.25 Sure Grip
Tires: 17x8.5 275 40 17
Transmission: 904 Auto
Engine:
LA Roller 318
Compression 9.0 Static
Heads 302 1.88 Intake, 1.60 Exhaust Comp 901 Springs
Intake Weiand Stealth 8002
Carb Holley Street Avenger 670 CFM Vac Sec
Headers 1 5/8 Long Tubes 3" collectors
Purpose:
The car will be a daily driver with the occasional trip to the 1/8 mile track near by.
Gas mileage is not a concern but reliability and road manners are of concern(over heating, very rough idle, excessive wear etc....).
The engine only has 70K and after removing the heads, the bore measured with less than .005 wear. Compression test showed an average of 155 psi. There fore I will run with what I have. Standard bore and stroke.
The heads are #302 and have been ported and gasket matched. Port involve bowl enlargement to handle the oversize valves and a lot of attention to un-shrouding the valves in the combustion chamber. Stock flow for 302 is around 175 cfm. Although I have not flowed these ported heads, I will feel confident that they flow 200+ cfm.
This 318 came from the factory with a roller cam along with all the supporting hardware.
So... given the above information I would like to regrind the original roller cam to what ever the consensus is from this post. Whoever regrinds the cam will also be what the consensus.
Why not just buy a new roller or call one of the many cam designers...? Well I guess I could...like everyone else...but this approach will help me what look for in camshafts and this ought to be yet another learning experience.
What makes this post different than the hundreds of posts here on FABO with respect to camshaft advice...? Because every one who contributes advice will see the result as I promise to have the cam reground by the consensus with the specifications by the consensus and will install the cam myself.
Time Frame:
Installed and running 1st week of Feb 2018; Regrounding company permitting.
