Re: what cam to use?

Most cams with any kind of noticeable idle are going to recommend that you change the valve springs as well....maybe look at the Comp Cams XE262H. You might be ok with the stock converter with this one. I would change the liflters and timing chain at the same time.

275hp 327 and not change anything else....yeah 262 or 268 would do.

Re: what cam to use?

the CC270H is the largest cam that you can put in before having to change your torque converter according to Comp.

I had one in my 327 until a lifter locked up and ate #4 exhaust lobe.
The cam has a nice lopey sound to it and performs really well. I had a TH400 behind it and was still able to spin the tires.

Do keep in mind that your compression needs to be taken in consideration as well. If your around the 8.5-9-1 comp ratio then that may be too much and you might shoot for something a bit shallower than .470 lift.

Re: what cam to use?

Also, you can try a Comp Cams THUMPR series stick. They have sound clips available on their website. They offer 3 different versions of the THUMPR:
1) THUMPR
2) Mutha THUMPR
3) Big Mutha THUMPR

Frost Green '68 Coupe (yes they made Camaros that year); Dart Alum headed, dynamically balanced 327; Mighty Demon 750; 4sp; Cal-Tracs Rear Susp; ProCar Rally 1000's seats; 15" Rallys. (pretty plain-jane)

Re: what cam to use?

you can run the 270 with a 350. It will be loose enough. BUT, it would be a dog without alittle compression.

Re: what cam to use?

268 and no larger on a 110lsa would be right at home, maybe a tad too big but it will have a noticeable idle and pull well, def make power in a wide rpm range.
Btw, I had one in a 210/327 with milled heads, decked block, 4bbl, hei, intake, headers, and other stuff too lengthy to mention and it really liked it (manual trans and 3.08 rear, cant speak for auto). I guess it had 9:1 maybe 9.25:1 with the milling and decking...

The only Mustang I'd ever own is a Fender.

A stock 275hp/327, install Cranes old 274H06 and it will have a nice cackle.

It's the 106 LCA that does it or else consider Isky's 270 Mega on 108 LCA.
