68MustangCoupe

Okay, I have an 87 GT I bought. The specs for the engine are in my signature.

http://m.summitracing.com/parts/TFS-2500100 Here is the link for the TF Spring Kit that came in the Car.

The Cam is currently the stock cam. I'd like something with good low end and mid range torque that sound pretty good at Idle. It is a Driving car so It needs to be streetable.

And I'm going to guess it has the 1.5 rockers, so I'm going to look into the 1.6

Thank you I appreciate the help!

stock was 1.6, ford 5.0's didn't come with 1.5's

I'd sure like to know what the installed hieght is supposed to be as well as the stack hieght so that I may have some idea about what they are actully selling.
They state none of that info in the description of the the springs.
I'd find out from Summit or TFS before I gave them any moneys........

Not sure what you mean by good sound at idle. A good low end equals relatively mild cam. Good low end and mid range would mean select something in the 220 duration range (+/- 5) at .050 with roughly .500 lift with your selected rocker ratio. Lobe center should be in the 112-114 range for a milder application like you're describing. Lower durations equate to smoother idle, better low end, and increased gas mileage. Higher durations equate to rougher idle, reduced gas mileage, and better top end (at the expense of the low end if the duration is greater than about 230). 220 duration is in the middle ground, but still with good street manners. Lots of choices out there.... You can always call a cam company and ask for their recommendation, they'll be happy to give you one.

Sorry for my vague question. I "would" Like a choppy Idle, But if it means I have no low end then I will stick with a smooth sounding Idle. I've read the Crower Baby Cam is a good cam for low end that "Sounds" like stock unless you know it's been changed. Right now I have a Stock cam with an AOD tranny and it only takes off once it hits second, First is just there, and only above 2500-3000RPMs. Just figured I'd get some advice on which cam to choose. I'd eventually like to put a T-5 on it, but if I have to stick with the AOD, I'd like a cam with good torque ratings. (Which I've also noted most aftermarket cams with AODs require a 20-25 stall)

And thanks for the info on the Rockers. Guess I will look into 1.7s Or at least 1.7s on the exhaust side.

Thanks

Just abit of opinion here but I've often wondered what people are speaking of when they say ' low end'. We have converters nowdays that make the meaning of that totally worthless.
