I'm getting a Comp Cam, but my original deal for a used 212/218, 522/529, 114 cam seems to have fallen through. Now that it looks like I'll be buying new, I have a chance to reassess and am wondering about the high-lift version of that cam, the one with 558/563 lift.

I plan on putting in new 918 springs, but was going to keep the stock retainers and pushrods. If convinced the high-lift cam would be better, I would be willing to swap out those as well. My goals are to keep stock capacities (payload, towing) and a stock idle, while gaining power across the powerband. No need to go higher than 6K RPM.

 

I think all you would need is the springs. I plan on getting this same cam or a 220. should make alot more power and very little tuning, plus keep low end and add alot of mid and high rpm power.

 

that might be a big cakm if you arent going to spin here above 6000. and if you are going to that cam and springs or any cam and springs for that matter i would install hardened push rods. do you hasve a stall. if not you might want to get it advanced like 4*.

 

P.S. - It's in my sig but I forgot to say, I have a Radix. And yes, I'll likely be getting a stall, probably the TT2600.

 

I would go with the low lift if your going with the TT2600. That cam is gonna want more than 6k rpms. Mine still hasn't peaked at 6500 rpm and it's not much bigger of a cam still using the XE lobes too. I think if you are dead set on keeping it under 6k rpms, you need to go smaller. The boost is gonna make that cam climb higher than it normally would.

 

I think the 212/218 .522/.529 would be well suited in your truck if you want to keep stock towing capacitities and low-end. If you want to go for the 212/218 with the XE-R lobes I would get a stall with it too. I went with the 212/218 .522/.529 because I didnt want a high revver or necessarily need to get a new verter.

 

There isn't any increased overlap between the two cams. Just more lift and more duration at higher numbers. Advertized durations are the same. That means its going to keep roughly the same rpms between the two. The high lift one will probably more more power all across the rpm range. It may extend power a tad further, but not much. I'd go the high lift cam even if it were a tow vehicle.

 

I am a big advocate of lift in street cars/trucks. To me; changing springs once every 2 years isn't a big deal. Id much rather do that than lope hard. There are very few things which can increase power/speed without effecting tameness. those would be lift, heads/intake, tuning and forced induction. Exhuaust doesn't effect it much but it goes without saying. Gears; it kinda sucks to cruise at 3200rpm.

go for it; i would!

 

Hmm, okay, so high-lift it is.

Should I replace the stock pushrods, and if so, who makes good ones?

 

Still wondering about the pushrods...Comp makes some Chrome-Moly ones, are these the right ones to get.

Also, should I get the Ti retainers?
