    No you don't have to. Us older guys get a charge out of these threads especially 318 cam threads I think. No perfect answer, no perfect cam, no magic bullet.

      It's a good thing I didn't spend my extra budget money on pistons and rings yet cause now i have to buy torsion bars! Projects are funny that way!

        If your driving on corners think 1" plus 1.1" etc
        do NOT install a rear sway without larger bars

        ON the cam get the heads and cr nailed down
        Measure twice- cut once
        keep up the questions

          I'm not installing a sway bar I'm just gonna put back in the Oringals size luckily a member on here give me a good deal on a set. I'm very thankful cause that was not in the budget but i learned from working on old guns when working on anything old things seldom go as planned!

              Back to engine stuff...... It is interesting how a few simple questions can grow and that's good. How we learn.

              The engine build questions would be great to first mention the intended purpose and all that we have to work with including budget. This thread started as "budget" build and that is what always gets my intention. Used to be my budget was a trip to the boneyard for a good 3838 out a 69 runnner!
              After so much discussion, the info all seems to run together. It would be great if everyone had the build info from the old mopar performance catalogues for basics. I know that is all old and antiquated but still serves a purpose.
              I look at return for $ when I do things. What needs to come first, like more HP or better brakes for a start?. Dead stock 318, can I use and love a better gear? Before I start spending $ on the engine? If I bang some gears and never see higher rpm's will a single plane be smart?
              We see tons of great discussion and info her on FABO, like the tread about... should I buy a crate engine, who's? or send mine to the machine shop? I know Joey will take all this stuff, write a book, get rich, and retire to the Bahama's!???

                Yea i agree the return for dollar is my main objective with this thread and I have learned so much i am still really lost on the cam suggestions but i guess i will learn more about that later. But I have learned alot more than I knew before about compression and flow and how the combo comes together. The bang for the buck side is what really interested me like if I spend 8 hours of my time with no money spent to gain .4 of a sec then to me that is time spent. I'm not sure how how that adds up to hp but seems more beneficial than spending 200 on pistons to gain 3% ! To me that's bang for your buck! I started this thread with the intentions of just building an engine that would start and run but the more I read and the more I learn the more I wanna squeeze ever ounce I can out of it! Lol i guess that is what makes us motor heads! Ok so with cams here is what i know the first two numbers the duration is how long they valves stay open the 2nd 2 numbers is lift the first being intake and 2nd being exhaust is the lift how far they open love separation is how far the two are apart other than that everthing else is Spanish to me i do not understand how any of the numbers affect other stuff like stall and power curve etc! I chose the cam i have because on summit website it said works well with stock converter and highway gears (that's me) and has a power range from 1200-5000 and the numbers where very close to a stock 340 cam which is what i was going for! I almost bought the 6901 and I didn't cause it said it runs better with 9:1 or higher cr and I knew I have about 8.5:1 so i read somewhere that it's better on performance to undercam than to over cam so i went with the milder one casue I didn't want to kill my bottom end!

                Ok after several suggestions from members I have decided to go with a different cam I have a couple in mind but im opening up the floor to suggestions I'm trying to save up for some pistons to give me a cr bump. But as of right now here is my combo stock 86 bottom end somewhere around 8.1-8.5 cr home ported 302 318 heads stock 1971 340 intake holley 1850 600 cfm carb and hooker full length headers. And 2.76 gears with 3.73 for later I dont plan on using the 373 rear end for a while so i need a cam to work with both. And go
