I have a stock 5.0 in a 66 mustang convertible. Want a more rough idle/lope but only want to change the cam. What is a nice sounding cam with a little performance boost good for a stock 5.0 HO? Running an AOD, has a mild performance stall, currently stalls just over 2000. 2.5 exhaust. Rear is 380's. Thanks for the help.

I'd go with the B303 cam. Worked for me in the past

You're going to have about a 1500 RPM power band with a B cam. The B cam likes RPM when matched with good parts. Match it up with stock heads, springs and intake and what you'll end up with is an engine with no bottom end that won't make power past 5,000 RPM.

You're gonna have to change the springs at a minimum. You may also need to change the pushrods but if you're the kind of guy that likes things "good enough" then they should be okay.

for a good lope get a 110 or 112 lsa cam, and since everything else is stock stay below 220* duration, and try to find a exhaust biased cam. 218/224 or 212/218 something like that so you can keep that bottom end =)...look at comp cams or anderson motorsports. TFS is always a popular pick as well.

also though i dont think the stock heads even flow passed .500 lift really

Are you running a carb? an e303 or tfs stage 1 is as far as you want to go with your mods... Even those might hurt your performance...

very true... you lose low end and some driveability with them. but thats the sacrifice for top end and a choppy idle.

Sounds like my best bet may be to leave the motor alone. Thanks for the input!

1.72 ratio roller rockers, upgrade valve springs, degree that cam and install it 2°-4° advanced is a better "upgrade" path based on your setup.

ya. advancing will give you loads of torque, keep driveability and you dont have to worry about going too "Big" for your heads.

On my '66 with a 5.0 EFI from a '93 GT, I installed a b-cam to go along with my JBA exhaust, H-pipe, 3.55 gears and PI torque converter. The b-cam sounds excellent in my config.
