I already have the TR 224/244 .563/.563 112 LSA cam with most of the bolt ons in my car. I made 374 rwhp and 381 trq with it. I am looking at either some heads, or a heads/cam setup. My questions are is it worth upgrading to the cam I have listed, and is there another set of heads I can get with a cam that will outperform this setup for around the same price (or cheaper)? Heres what i was looking at:

Precison Race Components Stg 2.5 LS6 Heads & Cam
Item# 25-PKG6 $1,939.99

Texas Speed Torquer v.2 Camshaft $0.00

Pushrod Length: | 7.400" Length (Standard) $0.00

Rollmaster Double-Roller Adjustable Timing Set $114.99

Gasket Kit: | Heads & Cam GM Gasket Kit $140.00

Oil Pump: | TSP Ported LS6 Oil Pump $134.99

_______
$2,329.97 Total

Like I said, I already have the TR224 cam, but I did not get a new timing chain or oil pump when I changed it out (I know I know). Any input you guys have is greatly appreciated.

 

With those heads, that 224 cam will only be down 10-15rwhp from the Torquer 2 cam, and will likely make better midrange. What you need to decide is if that extra power is worth another $500 and additional labor.

You're not going to find any better heads than the PRC stuff without spending another $1000 or more.

 

Depends on what you want to do. The TR 224 is a pretty small cam, but it makes much better numbers than the stock cam. I obviously like Futral's stuff and the Dart Pro-1 LS1, but it all depends on your budget and everything like that.

Ported LS6 heads are a tossup. Depending on how consistent the company is that ports them -- I sound like a broken record here because I know I've said it at least 100 times --- Flow numbers are only part of the puzzle -- Alot of how "good" a head is also depends on port velocity, turbulence, and on the LSx stuff - how you fixture the head during testing -- inaccurate numbers aren't going to be worth much.

I've read a ton of posts about heads, and all of them have posts from you, Kraest. I have paid a lot of attention to what you were saying, and I have noticed your liking of Futural cams and Dart heads. After reading about the Dart heads, I am under the impression that my cam is too small for them. I am most likely doing all the labor myself, so taking a few extra parts off to toss in a cam that will improve my power is not a huge deal to me. Although I do want my car to be driveable. I love the way it is now, but, as with everyone else, I want more power! I would be very satisfied with a stock cube motor, (although I'd love a 402-408), and make around 450hp. What setup would you recommend that will put me at about those numbers and keep my car driveable daily? Changing the cam is not a huge deal to me, so throw out whatever you have. Also, with those suggestions, where can I get what you mention? Thanks.

My buddy made 451rwhp with a ported TB and LS6 intake manifold with .030" milled Dart 205s and an F-14 cam in a Corvette with a dyno-tune.

I've had luck with the 225cc stuff. It's really up to you and how radical you plan on making the car.

Where do you get those brand of heads from? I haven't seen any on the sites I have been to.

 

Jegs? Summit?


You can call any shop and they can order them

 

Those Dart 205cc heads look like they flow nicely. But is it just me or is the exhaust side numbers a little low? (Just curious as I am just starting to learn all the aspects involved with cylinder heads).

So say I get the Dart 205cc heads, and keep my current cam, what else would I need exactly? Springs, retiainers, etc etc. I need to figure out everything I need so I am not ordering random parts in order to put my car back together (like usual for me ) My biggest problem when doing stuff on my own is not have everything all at once. I end up getting everything piece by piece as I figure out that I need it

I would like to replace all the stuff I didn't when I first changed out my cam, ie the oil pump, lifters, etc. I didn't do much because I was too busy replacing valves and sanding down the knicks in my pistons from the deuche bag that previously owned the car (I bought it from a co-worker and we went to the track, he took it for a run and went from 3rd to 2nd instead of 3rd to 4th.) I just did the cam because everything was apart already.

So help me compile a list if you have the time. Thanks for all the input so far!

 

TSP, VRE, Thunder...i think they all have the Dart heads.

they should come with springs that will handle your cam.

biggest thing would be to get them milled down to boost compression as much as possible.

another choice would be the Terminator 200s....nice flow numbers and small runners to boost low/mid range.


but if you say you want 450rwhp....you're gonna need to step up the cam. the TSP torquer 2 is nice and should do it, as would the futral F14 cam.
both should tune quite nicely for street driving.

but as for a list, you pretty much did it in your first post. but i would throw some injectors on there.

 

The exhaust looks like it was flowed without a pipe.

 

What size/brand injectors would you guys suggest?

 

After some more research, I have seen a lot of people say that the Dart heads need to have work done on them before installing them. Is there any truth in that?

 

Not true unless you want to mill them to raise the compression.

You'll want some SVO 30# injectors for a heads/cam setup.

I'd run the 225s

 

Many people are telling me my cam isn't big enough for the 225s and that I could easily lose power in some areas (mid range I think was what they said)

 

if you stick with the 224 cam....i think it could be possible.

but you said you wanted 450hp...which is gonna need a bigger cam. in which case the 225s woudn't be such a bad choice
