Another request for help selecting a cam. Opinions, please!
So lately I’ve been thinking of getting a cam and was hoping to hear some opinions. I’ve been reading threads for weeks but would still like to hear what you guys have to say for my specific needs. My mods are in my sig, basically full bolt ons. The car is not a DD and only sees about 2,000 miles a year, but not a lot of track time, mostly just cruising on the street. I don’t want to sacrifice all the streetability, but being I don’t drive it often I want a decent amount of bang for my buck. Was thinking something in the 228 range?
Also, I’m a bolt on kind of guy. Up until now, I’ve done all the work on my car by myself, but I have no experience with internals and don’t want to risk screwing something up, so I’ll probably have a shop do it. A local performance shop that did my dynotune said a cam install and tune would run around $900. Does that sound about right? Also, is there anything else I’ll need to replace while I’m at it? I guess I don’t really know if I need to replace rods or anything else, I assume that would depend on the size of cam I get? IIRC, I’ve read to also replace the oil pump with an LS6 and the timing chain with an LS2. Is that correct?
And before someone posts to wait on the cam (which I’m sure they will, lol) I know I need driveline work done. I plan on keeping the 10 bolt until I save up more money and getting a 12 bolt with 373 and a stall all at once, but would like to start up front and work back. Plus, I don’t have THAT much money to play with and want to get something done over the winter, lol.
Any opinions would be greatly aprpeciated. Thanks!
I've driven and ridden in some cammed cars that drove perfectly even though they had a cam that was considered a bit larger in them. The torquer 2 with a tune drives superbly btw. The car I drove this past weekend and may buy has a T2 in it and it is almost stock driving, and that's no joke. It sounds and runs great and is easy to DD...
Just a suggestion as there seems to be many guys who want bigger after their cam choices.

I'd call TSP and talk to them and I'm sure they will steer u in the right direction
The Best V8 Stories One Small Block at Time
Conservative:
TR224, 3200 stall, 3.42 gears
Mild:
TR228 or TR230, 3600 stall, 3.73 gears
Pretty nasty for a weekend cruiser:
RapTR, 4K stall, 3.73 or 4.10s
And as a sub for a Cam Motion grind for the previous 3 suggestions. Sub this for the first:
C33-769 LS Hydraulic Roller Camshaft; 224'/228', .578"/.578", 113'+4'; 1,900 to 5,900 RPM
Sub this for the second:
C33-790 LS Hydraulic Roller Camshaft; 228'/232', .612"/.612", 113'+4'; 2,200 to 6,200 RPM
Sub this for the 3rd:
C33-771 LS Hydraulic Roller Camshaft; 236'/240', .612"/.612", 114'+4'; 2,800 to 6,800 RPM
Hope this helps.
I'm not saying you aren't right, but I was just saying, if it were me I'd go a bit less conservative if possible since it's a "fun" car not a DD.
Not that I am trying to pick on any person but just an example from above that is the closest...
230/234 .600/.602 112+4 EPS
Now why in the world would you want that much intake duration to rev to the low 6000's? If you look at an off the shelf grind that has become somewhat popular from them it would be the 222/226 .597/.598 113LSA... it has a "1500 to 6800 RPM Operating Range." The power peak is going to be low 6000's with that cam. I know you tightened LSA and advanced 4 degrees but where is the peak going to end up? DCR isn't going to be pretty with stock heads and bottom end, and the overlap is going to sacrifice some ease of tunability and streetability. Potentially you can install a cam that peaks over 6500RPM in a can and only rev it to 6200RPM but why? You traded power/torque in the range you actually drive the car for imaginary power that is above your rev range.
To answer the above question by the OP about power loss, the short answer is yes. Will you miss it? I don't know. Everyone is quick to recommend cams that drive like stock, but how many of these are idling at 550RPM with stock stall? None... so really none drive like stock. Even the LS6 cam doesn't exactly drive like stock, although it is the closest to it... but it also does not make as much power. There is no free lunch and you will have to make some sort of compromise. The smartest thing you can do is come up with the rev range you want, which means what RPM you shift at and where you would like torque and power peak, then figure out what the rest of the combo is going to be like. The cam should really be the last thing spec'd after you know what else it is working with (excepting springs and perhaps tweaks to static compression...). You also said this car lives mostly on the street so you will want to keep mid range power decent, and dynamic compression decent... As long as I am speaking in generalizations a 228 wouldn't be terrible. I like the suggestion of the TR224 or Cam Motion 224/228 (might not install that with the 4* advance though).
