383man - Thanks Ron!
Gy3 - yeah, the TFs seem like a great choice for anything between mild stock replacement and full race, but your car is running great as is. I like the Gen3 hemi stuff too. I'd like to do an A body with that.

Glad to here you picked the 240s. Since you have a street (read,, heavy) car, 3.55 gears and a 4 spd, i definately think that is the right choice.

I agree,Greg. Thanks
Thanks Wyrmrider. I know a hydraulic roller (or solid) will make more power, but the xe284 is already in and running. That aside, I do think the "size" is about right for my intended purpose.
Thanks Zippy!

All in all, for a street driven car, especially geared the way yours is, torque is king! I have a somewhat similar situation; 2.97 low stick, 3.55 gears, 3800 lb car. Most of the fun driving is in the lower half of each gear. It may not have the ultimate combo for best ET, but it is the best "fun" combo for street IMHO!!

It's not the first time I've put something together that only made sense to me So funny. I just read through the rest of the thread, I'm definitely going to steal that..."story of my life" "It's not a race car. It's not a race car." We keep telling ourselves that. And yet..........

Thanks Zippy! My "voice of experience" says that you could spend a week on the dyno testing cams only to discover that the XE284 is roughly correct for your application. You might find cams that made more peak power, or ones with more bottom end torque, but I'd be surprised if you found a cam that made a lot more power at every point in the curve.

Your cam comparo with the mopar 528, racer brown, comp hydraulic, etc. proved that. Not exactly apples to apples w my combo, but iirc, those cams were all fairly close to one another in terms of power.

It is an 06 Mustang GT with a blower, making about 500 hp. The gears and torque curve are well suited to a street car. Lots of low rpm punch, and i don't have to rev it real high to step out smartly.

I was looking at this same sort of deal last year, and can offer what my experience was. I penciled out selling my 7 year old Stealths and getting into something new. But my math suggested it was still much more budget friendly to send my Stealths to Modern. About $400 still in my pocket is what I figured. Funds that could go to something else. They may or may not be equal to a set of TF240’s (I know... they arent), But they’re real close and I have the reassurance of knowing they’ve been prepped by one of the best head shops in the country.
I picked up a solid 2-1/2 tenths with the work and no other changes. My plans are to go to 1.6 rockers soon to make better use of the heads potential. My cam is .573 gross / .555 net lift with the current 1.5 rockers. The heads max out at a little over .600, so math suggests I may be leaving a little flow on the table.
I’m sure I’d be happy with new 240’s as well, but I’m cheap and the portwork was more within my budget. I also like the stock look of the Stealth head. It fits the stock vibe of my car, as I still run stock rocker covers, a dual plane intake, and all stock belt driven accessories, all painted up to look factory correct.
BTW: Count me in the camp that would LOVE to see the Dyno test described by Dwayne earlier in this thread!

I thought about porting my stealths too, but I figured cost wise, I'll just sell the stealths to offset the TF cost. I also wasnt as concerned about stock appearance, which is not typically the case for me. Not caring about stock appearance is actually freeing in a way...

Well, after thinking about it, I did decide to change the cam. I figured as long as Im changing rockers and need new pushrods (and the winter is long), I may as well try to optimize this combo. After speaking w Dwayne about my goals and driving needs, we ordered up a solid FT Comp cam. Here is a quick comparo of the new vs old grind:
Old - Hydraulic ft: 240/246@.050, .507/.510, 110lsa
New - Solid ft - 248/252@.050, .538/.544, 110lsa
So, not a ton different, but should make more power and take better advantage of the TF 240's.
Also, picked up a sweet 950 carb from BradH (to replace the 830 QF elec choke carb). Brads carb looks amazing and nicely baselined for my combo. He also Included a detailed build sheet and even some extras for tuning. He knows his stuff! Can't wait to get this engine running again. For now, it's just a deep freeze.

Factoring in lash, they look almost identical. I too would always lean toward a soild.

Sell the Stealths and step up to a max wedge port size or bigger My old pump gas Duster ran high 10.60s with ported big valve 906, ran 10.30 with CNC ported eddy RPM and ran 9.993 with a set of Indy SR M.W. size intake ports non CNC ported I did dyno test a set of CNC ported 440-1 on that motor and they where 50 HP better than the SR M.W. heads, I put the ported 440-1 on my bracket race 526 C.I. high deck 440 motor to sell it Bottom line is more air, more fuel, more power Good info, Cab. The 906 to CNC eddys is probably the type of switch I'd be looking at. That picked up quite a bit. Just head swap and no other changes? No other changes other than removing a set of CAT brand 1/6 ratio rockers to a set of Harland Sharp 1.6 ratio rockers due to the CAT eating up their shafts both sets of heads had 84.0 CC so the motor kept same the 9.25 to 1 compression ratio

Thanks, but please hold off on the praise until you're happy with how it's working.
