I'm comparing a 212/218 .522/.529 114LSA to a 218/224 .527/.537 114LSA.

Both are pretty tame street cams I'd think. I have a set of the 918 springs coming and plan to purchase some hardened rods at install time, also perhaps some tit. retainers.

Also, I have a 3000rpm Yank converter to be installed prior to the cam. After the stall goes in, I'll be running a high flow Magnaflow exhaust sans cats also.

Basically I'm looking for a cam that will make power to ~5800-6000rpm and perhaps shift around 6200-6400rpm.

If I purchased that 218/224 would that give me what I'm looking for or would the 212/218 be more for that? Maybe get the 218/224 and advance the cam timing 4° to get the powerband down?

Insight/ideas/input is needed.

If you use either of those cams, hardened pushrods and Ti retainers are not needed. Ramp rates are very low. Not sure if you're dead set on those cams, but there are better lobes out there that offer more power throughout the curve and will idle better. Comp has some lobes that aren't specifically LS1 lobes, but I've used them in 5.3L trucks before with great success. The lift is .538" and they can be had in the same .050" duration, but with much faster ramp rates. Even stock LS1 heads benefit from .550+ lift, so you could even check out the XE High RPM lobes too.

With the lower lift ones, I was considering adding some Yella Terra's in time to increase lift around .030.

What would you recommend for my truck?

i'd stay small in a truck, since its alot heavier than a car and u need more bottom end to move that weight... try the 212/218 cam on XE lobes, maybe on a 113lsa to keep the peak down under 6000...

If you're already thinking about more lift later, why not start out with the high lift 212/218 and skip the 1.8 rockers...that $300+ for another performance upgrade. I'm not a cam expert but I don't believe that you will lose much down low with the increased lift and you will definitely maintain a wide power range and drivability with the 212/218 duration.

Well I had a SLP 51011 cam from comp that specs at 214/222 559/566 with a 115lca. I just sold it too for a bigger one. If your looking for a great daily driver this or something comparible is what you want. With a Ed Wright mailorder tune, all the bolt ons, Moser 12-bolt w/ 4.11s my M6 Bird put down 372rwhp/366rwtq NA and 448rwhp/464rwtq with a 125 dry shot. Great daily driver with over 300rwtq from 2500rpm to 6500rpm (my redline). You can get away with ZO6 springs and stock ret./pushrods. Hope this helps.

I'm using the 212 218 cam. It's alright I need more cam. I have home ported heads and everything else is stock in a 99 camaro. I was at the track a month ago watching the races since my race truck needs another tranny rebuild, and I decided to see what the car would run. 12.78 1/4 at 109mph with a 2.01 60' and a .760 light. That ain't too bad for a baby cam.

The reason behind the Yella Terras is they not only increase lift but also have a roller tip, unlike the stockers (reduced friction is power). Also, I'm considering that lower lift 212/128 highly as I found a good deal on a used one...

Looks like everyone is voting for the 212/218.

Any ideas on overall power difference I'd see with the 212/218 over the 218/224? Would the 218/224 just make more power up top? Don't forget I should have enough stall to get through the dead spot of the lower powerband I'd assume too.

Hi,

I had this cam 3 years ago , its a great cam , when I had it I got the fastest and queqest e.t. for cam only car at that time ..... it was in the begening of 2001 ..... I have got 11.61 @ + 120 mph N/A ..... its a great cam and a streetable cam , and no one will notice that u have an aftermarket cam

Good luck

The 212/218 I presume?

There's also the 216/220, and the VHP cams.

I'm calling them this week for their 210/218 112 grind.

I've posted before in the truck section. I've got a buddy who has installed my two old cams into his truck. First the mid-lift 216/216 114, and then the TR220. His 03 5.3L runs great with the TR220. We both noticed a definite power increase over the 216 cam. The truck runs great and never stalls...still has great power for towing in OD. We specifically paid attention to see how its towing manners changed from stock to 216 to 220...Every time, they got better. Buy which cam you want, but from experience, the faster lobes are much better in every way. Also IMO, Yella Terras are overrated. Roller tips arent really the necessary. If you have the geometry setup right (which GM does), the tip never really scrubs the valve tip anyway.

I agree with MyLS1Hauls...I bought a set of Harland-Sharps for my build cuz I thought I needed to replace my factory rockers (scored up a bit...came from a toasted engine) and figured "what the heck"...only a few bucks more than new GMs. As it turns out my builder said he could've cleaned them up, and he tells me that dynos of roller tips (of the factory ratio) are showing no better than 6-8hp under 6000 rpm, or about the same as a dialed in set of plugs! If your stockers are good, your good.

I'm running the 212/218 comp cam in my vet. I added 8 degs. of timing up until the 4500 range with ls1edit and she flat out screams now with no knock.BTW you can have a higher lift with the same duration from comp. cam
(.553/.567 I think and not need new rockers.Go on line it's in there catalog.

To add to the mix...

I don't tow anything ever. If I ever do, it will be a max of 3000lbs like a lil boat.

Can someone explain how a faster ramp rate and such effect the cam's performance?

Abdulla

yes

My point about towing was to show the low rpm torque available. Faster ramp rates provide more power everywhere. They also provide a better idle. This is because there is less valve overlap at .006" lift.

216/20 on the 114 would be a really good cam Hitman. Personally whenever I come up with the money I am putting in the 216/220 or the 218/222 one or the other.

Hit Man X

Oh gotcha, so even those cams still towed well? Interesting.

I also thought of with the stall converter I'm getting has a 2.21 STR vs the 1.9 STR stock...so I may end up having more torque between 2000-3000rpm with the 218/224 cam and 3K converter over the stock cam and stock stall!

Do any of the Comp Cams have faster ramp rates?

Hit Man X

See, the 216/220 seems in between the 212/218 and the 218/224. I don't know if it'd be okay one way or the other. I'm leaning more toward the 212/218 as it sits now
