499.74 at the rear wheels is a bit much for me, but I'm getting used to it....still haven't run at the strip in that configuration, hopefully soon....

If it is really an option, I'd say to go with the 5 speed auto and do the necessary floor surgery. Can't beat taking ALL the modern conveniences and upgrades and stuffing them into a good old muscle car. Just my opinion  . And always remember, if its not fast enough, you can add nitrous and if it blows up you have an excuse to build it stronger to handle a supercharger or turbo hehe. Good luck.

I am thinking something like what you described, a 500 stroker with eddelbrock heads. Here is a question. I know nothing about modified motors. I'd just like something that really goes but runs and sounds very stock. I'd definitely want to keep the original HP manifolds on it and the original intake manifold. I could live with a different carb as long as the original dual snorkel air cleaner fit. So, is it pointless to build a motor like this if you want to keep the manifolds on it, will they pretty much choke off any major power gains? The original motor in the car is a 70 440 4bbl. If you assume that the original motor had say 300 HP net how much could a mild cammed eddelbrock head 500 stroker make, assuming it had to run well on 91 octane?

Well the stock intake and exhaust manifolds would definitely choke the thing for air, especially in a stroker.

I have a 1969 440 six pack Super Bee that has a new 523 stroker in it with factory exhaust manifolds. I built the car to somewhat F.A.S.T. standards as I like my cars to maintain a pretty much stock appearance. I have not yet had it to the track but it certainly "feels" like it will run high to mid 11s. The factory HP manifolds are not going to be a limiting factor for those kind of times.

Q: How much horsepower do I really need????
A: Just a bit more than I can afford.
Seriously, as soon as I think one thing will be good enough, I start thinking greedier.
This has led to several mid-project changes/backtracks/upgrades. Such as stroker kit, roller cam, tunnel ram, blah blah blah. So maybe I'm not the right guy to ask (not sensible). Or maybe I am the right guy to ask, since I've already been down that road...
IMHO, I'd be pretty bummed if my musclecar with a 5.7 or 6.1 swap got waxed by some late model thing with a couple bolt-ons. I'm speaking for myself and nobody else; I'm not saying "I'm right - you're wrong" Just telling how I'd feel and how I view stuff.
If it were me, I'd make sure that whatever motor I put in the ol' A-body had some performance upgrades, so that the only late model cars that'd take it would have to either have power adders or some serious wallet thrown at them.
-bill
Seduce the attractive, and charm the rest.

489 C.I.D., roller cam, aftermarket heads, tunnel ram, stock '54 Dodge rear axle assembly: which of these doesn't belong?

talking about power, gears, and streetability...my stroker made 505 on the dyno...add on all the accesories, full exhaust, drivetrain, engine compartment...I'm probably at around 380-390 to the wheels.
with a 28.5" tire, 3.21 gears and the TKO-600 w/.64OD 5th gear, I cannot use 5th gear until I'm going 70 or better, otherwise it surges and lugs as I'm cruising. 70mph in my set up is only around 2100-2200 rpm, and I definitly have too much gear. when I wound it out through the top of 4th gear, my speedo was maxed out at over 120. it got there pretty quick, but I definitly don't need to be going that fast especially in 4th gear with all of 5th left.
Something else to consider with a "long stroke, high torque motor" is that with a high gear set up, and a manual shift car, you're going to have to slip the heck out of the clutch to get going. City driving can sometimes be painful because of how much I have to slip the clutch when pulling away from a stop.
I just ordered up a set of 4.56s to help me with that problem though, hopefully now I can roll around at 1100 rpm or so in 1st gear, and actually be at a safe, slow, parking lot speed!

Don't tell that to a few guys racing FAST ...

That sounds like what I am interested in. Pretty much stock apearing but significant power upgrade. What heads, intake, compression and carb are you running?
To run on 91 octane you want to keep your compression in the 9.5 to 10.0 range with the alum heads .
Talk to fast68plymouth and/or DRAM about what you want and have them spec you a build and a CAM , you will not be disappointed .
fast68plymouth is the head porter/cam spec behind many of the fastest big block wedge headed mopars in FAST

Depens on what you can live with regarding street manners in terms of idle and bucking at cruise speed. If you drive it regularly in heavy traffic you will want to take this into consideration.
I agree. I had a big mechanical and a single plane. NO FUN. MP528 and a dual plane on my 470" and it's a BUNCH more fun to drive (drove it to work today). Still probably near 600HP.
Could I use more? Yep. I've always wanted a blower car. The owner of an auto repair shop down the street from me drives a blown BB Chevlle with tubs and cage. NICE! I drove by one time while he was pulling in the driveway of his shop. When he lit em up it sceeeeered ME so bad I thought a jet was crashing near by - all the noise and vibration was INCREDIBLE.
Kinda like the how many licks to the center of a Toostie pop - the world may never know  But I'd say MORE than 600HP.
I lit em up for about 10 feet last night and my wife was so sacred by the NOISE she said if I ever do that again she'll never ride in my car again I'm gonna see if she's serious.

That sounds like what I am interested in. Pretty much stock apearing but significant power upgrade. What heads, intake, compression and carb are you running?
The cam is a roller with 112 degree lobe seperation. Intake .022 valve lash hot .630 valve lift 284 duration Exhaust .024 .608 288, and after indexing the lift is 420/244 I and 405/252 E. The stock heads were ported and flowed. Of course it is balanced and blueprinted. For some reason the compression is not shown on the blueprint sheet, but it will run on punp premium. I have the stock original six pack intake and carbs with all of the Promax add ons. With all of the parts and labor I have around $11K in it including R&R.
Some of the winning F.A.S.T. guys are running up to 14:1 compression. We do not have F.A.S.T. racing here in the southwest and even if they did I would not go to those extremes. I want something that is still streetable for a 2 hour drive or more. My car is borderline as it has some around town surging due to the cam.
