jon521 Posted November 9, 2011 Report Share Posted November 9, 2011 I will be picking up a peanut head soon from crackerjack, and will be rebuilding and i am considering putting in an aftermarket cam in it. Does anyone have any suggestions on different types of cams? i will of course be researching on my own, but i always like some ratsun input :) thanks! Quote Link to comment
crackerjack69 Posted November 9, 2011 Report Share Posted November 9, 2011 I hear of a lot of folks using Isky. Worth checking out. Also, people have the stock cam ground at a shop, that's how mine is. Quote Link to comment
wayno Posted November 9, 2011 Report Share Posted November 9, 2011 What exactly you want out of the engine, grunt power, high rpm screaming, ???? Drivability? I put a RV cam in the last W53 head I had rebuilt, I now regret that decision, I lost torque(grunt power), I rarely run the rpms over 4300rpms, so a stock cam is good for me. Keep in mind that I am a big fan of big valves though, I put 280Z valves in one of my W53 heads, they really don't make much of a differance till I hit the hiway, then the big valves shine. I put a RV cam in a W53 with stock valves, and hit the hiway, big differance, lost torque starting out because of the cam, lost power on the hiway because of the small valves. I wonder if they would let me run that truck at PIR, as I would like to see how it does, wouldn't that be funny, a dually running the 1/4 mile. :lol: Quote Link to comment
jon521 Posted November 10, 2011 Author Report Share Posted November 10, 2011 honestly i am not exactly sure what i want yet, but i know i want grunt power, but i would like to take it up to portland or on the highway every once and awhile Quote Link to comment
yello620 Posted November 10, 2011 Report Share Posted November 10, 2011 Jon, keep in mind the expense to do a L motor cam properly. By the time you buy the cam and rocker arms(not the chinese ones either) and lash pads it becomes a pretty expensive venture. There is more involved that just the cam to do it correctly.

jon521 Posted November 10, 2011 Author Report Share Posted November 10, 2011 hhmm i didnt know that, good to know. what else is involved? Quote Link to comment
yello620 Posted November 10, 2011 Report Share Posted November 10, 2011 Jon, i honestly dont know all the details on installing an L cam. But i wanted to share what i did know so it might help you search for the information. I has been my understanding that to do it properly, it usually ends up costing around $400 buck if you do the labor yourself. And that is if you dont get to big of a cam that would also need valve springs installed. Good Luck in your research, i remember a couple good threads here on Ratsun too. 1 Quote Link to comment

wayno Posted November 10, 2011 Report Share Posted November 10, 2011 The more radical the cam, the higher the rpms needed to reach its potential, it also robs torque(grunt power) from the lower rpms. I use stock cams, as I don't run it up to 6000 rpms in my normal driving. Fact is, if you drive it like that, it's not going to last long term, but I am sure some will argue that point. My last work truck engine lasted over 10 years, a guy I paid to help me last summer said I beat the shit out of that engine, but I rarely hit more than 4500rpms, it had a stock cam, with big valves in the head. But I did change the transmission 5 times(4 were doglegs), about 4 rearends(one dually, 1 488 gear, and 2 437s) before I retired the engine. I also got away from them 200mm clutch discs/covers, they couldn't handle the work truck duties. Here are some of the work truck duties. Quote Link to comment
banzai510(hainz) Posted November 10, 2011 Report Share Posted November 10, 2011 I would start out with a Minimum 475/275 isky cam But to get the full HP out of these its best to put sidedrafts. Isky webcamshafts Schneider Erson maybe some other made cams cames cost money to do it right. Maybe bolting on a 38/38Weber might be EZer to do.If you find one used. Quote Link to comment

Just use an L20 cam,Cheap and grunt power,If your running an L20 you dont wanna rev past 6Gs anyway unless you balanced the bottom end,+ you have to run high compression 9 1/2 to 1 or higher to take advantage of a hot cam Quote Link to comment
