TFS Stage 2 Cam

January 15, 2012, 11:31:11 PM

I'm going to have a 306 built with Vic Jr heads and 9.5-10.5 pistons, Torker intake and 650 carb , 2500 converter and 3.73-4.10 rear ( it's a turbo coupe rear that the seller said had 4.10s but I have no Idea it was cheap and close to home) . I was wondering about the low end of the TFS stage 2 cam in one of our cars . I wanted bigger cam than a stage 1 but I don't want to give up too much low end .

A 2500 converter isn't enough for the Stage 1 cam, with the S-2 it won't have any bottom end... You may want to rethink this...

Spend once and be happy with the result.

Call a custom grinder or two and get an idea....

Not everyone has the money for a custom grind, and for a street car a trickflow cam will be fine. We arent racing top fuel. Im not upset, just saying.

@ Ricktjr, I think you'd be happyer with a stage 1. They pull good to 5500 and 2500 stall would be ok with a street car with a stage 1.

Just my two cents, Bigger usually isn't better for a street car. I've known people that have huge heads and cams in street car that will not fall out of a tree.

If you're running efi still I would steer clear of the stage 2, I'm running it and I've had nothing but problems with idle. Granted you can get it tuned or buy the hardware or software yourself, (which I did) or you can run the stage 1 which gets along well with the computer and save yourself a tuning issue or a carb conversion.

The Comp cam I'm running cost ~$270. I could have got a custom cam for $300. I probably should have.

The cam I'm running is a high lift, low duration cam. With the 2800 stall converter it will blow the tires off on the street.

What are your goals for the car? Is it a strip car or mostly a street car? If it's a mostly street car I would look at something that makes good low end torque but also pulls to 6000 rpm.

With the TFS heads, TFS cams are custom, specs were determined after heads were designed... My Stage1 and TFS heads will pull hard all the way to fuel cut at 6250 RPMs...

Street car and yes that's what I want .

Tom, I run the same heads and intake and swapped out the stage 1.... I found more power throughout the entire operating range and better gas mileage. To be honest, I was never satisfied with the low end on my stage 1...... Even with the converter I ran at the end (2800). I never hear this complaint from 5 speed guys that run it, however I'm not the first auto guy to have disappointment about low end grunt....To add, I took quite a bit of weight out of my car as compared to stock.

Not to mention the OP isn't running TFS heads.

Just because it was designed after doesn't make it "custom. My cam works for MY combo. Not just the engine. The transmission, gears, tires, weight, converter, intentions for use of the car......

Throw 10 pounds of boost at a TFS headed 5.0 and I'm sure there are a few off the shelf grind cams that would be better suited for the dragstrip than a stage 1 in that particular application.....

The TFS cams were designed to complement the heads, specs were determined by using the heads flow numbers, to me that's custom... True the main consideration would be in a lighter Mustang, but that doesn't make them any less custom...

On that basis an e-cam could be considered custom. I'll respectfully disagree. I understand the point you are driving at though.

i disagree as well.. in that mind frame, 90% of the cams on the shelf are 'custom,' as they were designed for optimal performance with a certain head combo.. a custom grind, however, is built around all aspects of the motor.. including heads, pistons, bore, intake, carb/injectors and induction type

The problem most people make is getting too big of a cam for a "street" car. Most would be happier with a mild cam. I dont know for sure what cam I'll pick when I decide to change my heads and cam but I know that I want good power to 5500 - 6000 rpms. The Trickflow stage one seems to be a low cost ($180) option. I have personal seen these cams make very good power on a dyno. I installed large valves and ported GT40 heads on my freind's 306 mustang with scat rods, je piston, edelbrock rpm efi intake, 24 pound injectors, with a custom tune and the car pulled 320 RWHP. The same guy put a procharger on and pulled almost 400 with low boost. They might not be the best option but Im just saying they're not a bad one.

my favorite low budget cams.. howard's! they make awesome power for their wallet friendly price of $100 or less

Not to mention all the stuff AFTER the motor that applies the power to the ground.

I must say -- I've been absent from these boards for a while as I was despondent concerning my Cougar's bodywork/repaint progress (it's finally almost finished). I had forgotten how nice a healthy discussion concerning tech was with the members here.
