73cuda340 OP super stock Joined: Jun 2007 Posts: 1,184 clarks summit pa	Im in the works of building a 416 for my cuda. Right now the plan is for 10:1 compression, ported 2.02 J heads (don't know the flow numbers), Holley 750 double pumper, Edelbrock RPM Air Gap or LD340 (have both), Comp XS272 236/242@50 .502/.511, Hooker competition headers with 2.5" exhaust with flowmaster super 40's. Any guesses on what it will make and if it could possibly 11's? It will be in street trim with a 4 speed and it has 3.23's right now but will probably try 3.91s or 3.73's if I can find them. 1973 Cuda 528 all aluminum Hemi, 4 speed, 3.23 Sure-Grip, (JA5) Silver Frost Metallic 1973 Challenger Rallye 340 1985 W150 Power Ram prospector 1986 Camaro IROC-Z 305 tpi

I ran 251@ .050 in a 410 sb, 10.2:1, RHS heads, rpm intake, 750 holley and small tube headers and it made 517ft.lbs.!! That was a 295HL hyd. shelf cam! It made peak HP at 5400rpm with a 1" open spacer and had to jet the carb up some. Carried HP all the way to 5800 rpm before dropping 10HP. Brian Hafliger

These smaller cams that you are looking at would be fine in a truck,or VERY mild street car/truck.

There is no loss of low end with a stroke longer than any factory big block. A similar build I did a couple years ago runs close to the same setup: 9.6:1 forged dishes, ported (by me) "308s", a Crane 248�/258� hydraulic cam, and a Street Avenger 870 VS carb. Makes about 460ish hp by the mph/weight. Running a 750 dry flowed carb on these tends to give them a big drop in power around 5500. Least every one I drove with one does...lol. Like turning off a light switch. That XS272S is a truck cam, yes. Like an RV cam. Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

OA5599 super stock Joined: Jun 2006 Posts: 834 Beavercreek, Ohio	I have one suggestion. I run Dynomax Ultraflos and temperarily switched to a 40 series 2 chamber VX series (Flowmaster replica). I didn't get 100 yards in the car and noticed it was way down on power. I like the sound and get way more compliments with the Ultraflos too. I switched back and gained all of the power I had lost. This was on a low 13 sec 8.5:1 340 with no stall. I'm sure they would hold back your stroker even more than they held mine back. I have read similar stories after doing some research.

There is NO DOUBT about this.
