Hey guys thinking about just doing a 3/4 race cam with a set of new springs. think the stock throttle body, intake manifold and exhaust will hold me back? i will have it tuned

 

3/4 race cam lol, sorry that makes me laugh everytime I see it, what year are you working on, I'd definitely do a full exhaust at least

 

prob have 250 600 114 cam and yeah headers are on order

guess i could say stage 2 or stage 3 cam? lol

 

Automatic or manual? if your running auto your gonna need a stall converter and tranny cooler. I would defiantly get headers/exhaust and atleast and ls6 intake manifold.(if you you have 01 and up it should already have one) The stock TB will choke it up abit but with a ls6 intake and ported polished TB you will be fine. You can buy a 4 bolt conversation spacer for the ls6 intake and put a 90mm throttle body that would really make it breath. My buddy put down close to 390 rwhp with a big cam(234/238 duration) with ls6intake, P&P TB, headers/exhaust.

 

The stock intake and exhaust will definitely hold you back, but you will still see some gains with a bigger cam.

What are the specs on that cam? Was it spec'd out exactly for your setup (eg. ls1 intake and oem manifolds)?

 

Yes a better intake and TM will help, but why such a large duration cam? You do realize that unless you match it with the right heads, have the right gears, the right torque converter (if it's an auto) etc...it will actually be slower than a smaller correct sized cam right lol?

 

First do some research. 3/4 race cams do not exist.

 

I was always a fan of the less popular 2/3 street cam... its a bit more tame than a full 3/4, but not as bad as the monster 7/8 mega cam. And dont even get me started on the 1/1 cam... ridiculous.

 

LOL

Good laugh in the morning.

 

Is this similar to an RV cam?

Also PTV clearance may be an issue with a cam that large.

 

The larger of a cam that you go with, the more crucial it is to maximize all of the components in your system (the engine). Failure to do so will critically effect daily driveability. Therefore, it's easily said that larger cam system builds are more expensive.

Honestly if I were you, I'd do some research. You don't have to pay 2000+ dollars for some good heads. There are some highly reputable places out there that can port some 243 casting heads or even the ones that you have on your car right now, which will net you a lot more flow. Check into Advanced Induction and TEA Heads. You already mentioned the fact that you were for sure getting new valve springs. Get the Brian Tooley Dual Valve Springs. These are not only cheap, but also one of the better valve springs to go with at this current time.

You can pop for an ls6 intake for around 500 bucks used. 800 new from some of the vendors on here. Also as addressed above, if your car is an '01 or '02 model then you already have the ls6 intake.

Here is the order of intakes from least power to the most powerful:
ls1 < ls2 < ls6 < ls2 ported < fast 90/92 < fast 102 < fast 102 ported

Porting an ls6 intake is possible. However, you need to find the right person to do it. A properly ported ls6 intake will net you decent power over an ls6 intake.

Texas-Speed offers very cheap yet very nice long tube headers. Your car will not only sound MUCH better but also flow much better. This is what I personally have on mine and I couldn't be any happier with them.

Gears. Very crucial. When you run a large cam, it is going to be much more crucial to reach higher RPM's to get past the bucking/surging at low RPM's. A lot of people recommend either the 3.73's or the 4.10's. In the future I will be going with a 235/243 SNS Stage 3 cam, so I will use the 4.10's. Don't go cheap with gears though. Make sure you get a good quality name. Failure to do so will result in a lot of trouble later on. A lot of good things have been said about the Motive/Richmond/Yukon companies for gears in these cars.

While you're all the way down in the engine like you will be, then you might as well replace the oil pump. '98 model cars are a lot more prone to oil pump failure than the other year f-bodies. I personally replaced mine with a Melling High Flow Oil Pump.

These are some of the basics. There are a few components that I left off. Feel free to PM me with any questions.

 

 

Are you sure?
I run a 5/8 cam myself, so a 3/4 isn't out of the question.

 

all race!

 

Personally, I like the 13/16 race cam.

 

I am running the tick performance polluter v.2. I gained 80rwp with this cam.

 

Yes, they do.

 

I don't have enough cojones to go 1/1...


I did sack up and order a "29/32" cam for my 5.3 though...

 

With all due respect, y'all are being ********. "3/4 race cam" is a term used back in the day. OP is probably and older gentleman.

JudgeGuns, times have changed. No one refers to cams this way any more. Your best bet is to call a vendor like Tick Performance and ask them their advice.

 

^^^^THIS!!!

3/4 cams ABSOLUTELY DO exist, and my guess is the OP is defiantly old enough to be most of the people who commented father or grandfather.

OP, research 224 cams...streetable and can make tons of power. I think this would be exactly what your looking for!
