MD-

Since you obviously take it personally when people run more cubes than you let's compare the actual cost of building a 400 rotating assembly verse the all might 461 that you like to claim is such an expenditure.

To keep it all on a level playing field I'll use prices from PPR using the same parts in both

400:

SRS Pistons: $455
Total Seal Rings: $123
5140 6.625 Rods: $228
Say you own the Crankshaft, Pontiac 400N
Crank Magnuflux and Grind (10/10): ~$175
Balance: $250
Rod Bearings: $55
Main Bearings: $65

Total: $1351


Balanced 455 Assembly with exact same parts from PPR:

Total: $1350


Maybe he went with the stroker because it's cheaper? I even assumed in my example that he owned a 400 crank!

torque is also a measure of power(real world,useable power at an rpm range that people drive in on the street)500+ft-lbs is way more torque than ANY 400 with stock heads and intake from the factory,should be a blast to drive on the street.If you're not going to drag race,who cares what the HP # are at 6000rpm?Who drives around at 5500RPM,any way?

71firebird400, When did I ever mention a price comparison, or which one was cheaper to build?

How much torque is at the rear axles?

Torque is a measure of power?????

WRONG, HP wins races!!!

You'd think that a stroker kit would've made more power than a 400 with unported factory heads, wouldn't you?

Right Here, Motor Daddy! I'm reading between the lines and it's pretty obvious that this quote says that you thought the stroker was wasted money when you're lowly 400 made more power. But maybe he couldn't afford that prestigious 400?

Oh MD, you're such a clown!

Thanks. Just trying to liven this place up a little and have a little fun.

[71firebird400]

Nothing wrong with that, can you figure out my Holley for me!? I hear they're dogs compared to Q-Jets, but it's what I got

I guess I overstayed my welcome on this thread already. Start a new thread and I'll see if I can help.

HP=the amount of energy expended to lift 150 lbs 220 ft in one minute.Power=torque X2pi(3.14)Xrotational speed.Torque is NOT a measure of POWER?Ha Ha Ha!What does it measure then?Go ride a Harley-Davidson around the block,let the clutch out a couple of times at 2000-2500 rpm,(torque monsters,even when stock)then jump on any high revving jap bike and let the clutch out at the same rpm.Even you will now become aware of the difference between HP and torque,and why ahigh torque motor could be alot of fun in a street car.Besides,I thought all the high-horsepower,low torque crap was for the small-block chevy guys?

My ZX-11 rice rocket had next to no torque, redlined at ~11,000 RPM, and ran the 1/4 at 10.2@131 MPH off the showroom floor. What does that torque monster Harley run in the 1/4 off the showroom floor?

[paint guy]

not as fast as your rice-burner,I'm sure but it does'nt matter,you just proved my point.How often did you drive around on the street at 11,000(or even 7000)RPM?The original post had to do with building a STREET car.

I ran it every nice day to work for over 2 years at 175+ MPH, banging every gear at 10,000+ RPM at WOT.

If I wanted to putt around I did it at ~1/8th throttle in 5th gear, where the engine made an incredibly small amount of torque. If I wanted to go fast I would downshift to second gear, nail it, and take off like a bat out of hell, proving once again that a higher numerical gear and higher RPM accelerates at a much greater rate than a lower numerical gear and lower RPM.

You are talking about streetability, not power.

High RPM Is Really Hard On Pontiac Engines over time Thus the need to build Power at lower rpm where its usable in a street car that has to last more than one season, Build for Torque and HP will come, What ever car has More Torque and HP delivered to the Ground Wins, A Posi rear end and Stcky tires are needed with most Pontiacs, from a 400-601 they are all good just depends what ya wanna do and How ya Drive, And If it makes you happy By all Means Do it, My 2cnts

[ksgto]

For everyones info I probably do have a small cam in this. A couple of reasons I built this is one this is a graduation present in 4 years for my daughter and if some time down the road I want to put a larger cam in it it will hold it. I will have all the info from butlers paper work come mid week and will post it for everyone.

I'll get back to my original statement it all depends on the dyno! Lets see my pump gas 455 motor that only dynoed 525 HP at the flywheel runs 10.99@ 124 in a 3750 lb car(check the Moroso slide on it). Now pop Hot Rodding 626 hp 496 BBC in a lighter Chevelle run slower and less mph(11.30@117)-hmm which dyno is closer?? Oh and that's the same dyno lots of the magazine tests are run on.

[gtofreek]

I get it, MD has never riden in a well built 455. That's got to be it!

[Scott Stoneburg]

MD, i have a question for you. Why would you want to come onto this thread and throw down on this guys day, he is obviously happy with the performance of his combo. he didn't start this thread asking if we thought his combo made enough power. seemed like he just wanted to brag about finally having it come together.i for one am happy for him, great job ksgto. sounds like you'll have plenty of fun.
