12's with a 3.23 gears and small block is a little optomisitic.
i broke into the 14.9's with a 323". 188/160 318 heads. performance cam. 770 holley , single plane intake, low gears , 4 speed...sig
unless you add gear, then stroke it, or 3800 stall it. you wont get there.
What size tire???

And you would be WRONG!
Not the first time around here.

Hard to go wrong with it. Good luck and let us know what you decide to do.
called another buddy of mine and he has a set of W2's for sale.
Trust me. My demon has a 360 that makes a little more than 300 at the rear wheels. My 3.23s paired with tires that are 25" tall turn into 3.73-3.91s. In a car weighing 3375 and low gear set, it will run high 12's
On the other post, do you mind me inquiring how much he wants?

How good are the heads. If their in good shape I would swap. You would have no problem making 400+ hp with W-2. Unless you plan on using the tranny. Then you could probably settle for a set of OOTB Eddies

That trade is a no-brainer to me.
Aluminum OD trans maybe $100, W-2 if decent are worth much more. OD transmissions aren't worth a whole bunch.
If they are bare w-2's you'll be spending a good chunk of change on rocker gear.
Get a part number off or pics of the w2's and someone here can tell you exactly what they are.
Good luck with it.

if it were me, I'd find a core magnum 360 to build.
KB107's at 0 deck, go through the heads and port per steve dulcich's article from mopar muscle in 2005 MP springs good to .6" lift, or if the heads need new valves or have loose guides, run chev 11/32 stem valves .1" longer than stock (hone out stock 8mm guides to size) stock rods w/good bolts eddie air gap reuse roller lifters, look for a roller cam with ~224@050 duration-I kinda like the comp XR series retrofit rollers if using the comp cam (lots o lobe lift) I'd use some 1.5 ratio roller rockers

Why would you recommend roller rockers on a small cam with not that much spring pressure. they are absolutely no help in the power department. with big cams and heavy springs they help reduce side loading.

why'd I recommend them? my biggest reason, to get reasonable lift w/the cam suggested (comp XR274 retrofit roller), which is ~.540" valve lift with 1.5" rockers. it's a very aggressive ramp roller cam (it's ~274 adv. duration, 224 .050 duration, and like I said, ~.540 lift w/1.5 rockers), and using the stock 1.6 ratio magnum rockers would increase lift to .576" lift on that short duration. I'd be afraid of valvtrain harmonics and the hydraulic lifter not being able to keep up with that much lift for that short of a duration cam, which would limit RPM to under 5000 or so.
Steve Dulcich had a similar problem running a comp XE275HL with 1.6's--it was just too aggressive for the hydraulic lifter to keep up.
those MP springs I recommended have 131lbs on the seat installed at 1.625" and 305lbs at .5" lift, so they're relatively beefy.
another issue would be to reduce lift, since it's hard to get a lot of installed height on stock mag heads w/stock valves.

I don't thinkg that those springs installed at 1.625 have enough lift before coil bind for that much cam. Coil bind would have to be in th area of 1 inch compressed spring. You also have to remember the guide to retainer clearance has to be correct or a major malfunction can occur there too.

I am using the exact same cam with crane energizer 1.6 roller rockers with no problems at all. I think dulcich metioned that reducing the weight of the valves and valetrain would help with the high rpm problem he found. I am using hollow pushrods as well as the 8mm thin stem valves and my 390 rips pretty good all the way to 6,000rpm without a hiccup. TBF
