Very possibly tonight , ill be picking some parts for a new setup still vh centered but ill be moving away from the needing the cams and such.

These where stevens (superhatch) head they where assembled at m2 racing, with the mazworx 272 cams , with supertech vavle springs and titanium retainers. Also comes with arp head studs, ive never ran them, pretty much sat on the shelf for the last few months, they are pretty much drop in.

2100 shipped to the lower 48 , will ship overseas for extra.

jerry definitely interested! trying to sell a car to pay for them! i'll keep in touch!

ill do a payment plan, or take non refundable deposits

Tell me this has anything to do with the picture you sent me via email not all that long ago...

kinda sorta

any headwork?

5 angle valve job and hand blended bowls. Decked head surface. Otherwise stock...

heres a preview

wow

So how Hot are the cams ? what is the expected output increase ???James

it is expected according to stevens gains to be about 50 crank hp

remember of course that whatever gains you get would require a full ECU retune...

Not trying to deter anyone from buying these, but be fully aware that a full ECU retune will be required to get full gain from these..

" gains to be about 50 crank hp" I assume you are speaking about gains on a super/turboed engine not NA.

Based on cam numbers it appears you might get 350 fwhp with ecu tune on NA.The major problem is the runner/plenum tunimg of 5850 rpm [5500 and 6,000 with a mild dip at 5850] at 77F.

The reflected wave will fill while valves are too open so some loss of torque is expected in midrange.

For the record, I gained 38WHP with these heads bolted to my motor, untuned.

I don't really care what anyone else thinks they should or shouldn't make, those are real world results.

I would think with a tune, Jerry's estimates would be dead on.

Tech what in the world are you talking about ,these motors make almost 350 crank hp stock with headers ecu tune and a good exhaust, ive dynoed on several dynos between 285 and 295 Wheel horsepower, assuming that 15 percent drivetrain loss thats 340, at the crank

*****edit and steve to clear the record i was being conservative and said 50 Crank horsepower not even wheel, judging by your 38whp, thats a "bolt on" 50 crank hp right there.

I could careless about horsepower [without @rpm specification].I've dynoed mine [8 times] with ecu retune [since 1994] and loud exhausts never got. over 322HP/ 331 lb/ft. Of course if you delete cats [4] and don't comply with emissions you might gain another 20-25 [?]. But we have to be legal here.

I assume your selection of 15% driveline loss was for a manual transmission. Again there are no oem manuals in US.

well to be clear i dont think there are any oem manuals amywhere in the world lol, im just saying that these motors are capable of near 350 crank hp with out any mods other than i/h/e and ecu, so to say these cams would only get you to 350 crank is flat out rediculous.

I mean you prove the point yourself with your dyno numbers removing the cats youd be at 350 so i dont really get what your saying, plus if you had a manual youd probably free up some more power.

if you want rpm specification at my last dyno at sealevel on a 95 degree day 289.6 wheel hp at 5800 rpm 292 wheel tq at 4200 rpm.

look i respect your years of experience and all that, but at the end of the day real world results are real world results, according to the math on an sr20 putting a greddy intake manifold should ruin the power band yet you lose 20 lb ft of tq below 3000rpm and gain 50lbft above that.

Also remember these are performance applications as most people here have vhs swapped in sub 4400 cars, losing a bit of tq down low is not gonna be noticed, as it will shred the tires anyway

What brand chassis dyno did you use. I didn't understand where/why you assumed a 15% drive train loss since I use 19- 21% depending on tires and ATF temperature.

Are you speaking of an off road only application or a legal emission passing application? Cams per se are an illegal change on a street car.

brand of chassis dyno was dyno jet, as for the 15 percent, it is commonly infered that manual transmission cars soak about 15 through the drive train whilel autmatic cars are in the 20s ( which would only reinforce my point even further).

As per emissions legal or offroad, we dont have emmisions testing or refs or even vehicle inspections in florida so i wouldnt even begin to be able to know what would make you exempt or not, i can tell you my car is a state title and insured street car, obviously not my daily driver of course.

One thing i can tell you is a good condition, performance oriented Vh45 will make 340 crank hp all day and night without touching the internals of the engine or forcing air into it, ie bolt ons only.

Even that guy riswicki or whatever his name was back in the day made something like 287 whp, in his q45 with headers, ecu and exhaust, going by 20 percent drive train loss thats 358 whp, with no cams or nothing.

I only trust the dynos I calibrate myself, as many operators try to pay their bank note on the backs of inaccuracy.............repeat business because their dyno reads high for publishing on Inet or in magazines.

The best I have gotten with just a tweeked ecu is 318HP, now japanese manifold [no precats] added 7-9 HP and a very loud exhaust was good for 7-8 HP so we are at 333-335 HP bring that down to sealevel [from 1,000 AMSL in ATL] gets you to 344-346 HP on a perfect day.

Obviously gasoline is a real variable not sure that the current low btu E10 will meet the earlier dyno tests, as the BMEP would be 10% lower now.

So to sum up this thread

1. Q45s can make 350 crank hp on the stock motor2. You cant argue with q45 tech ( its a joke but really)

most importantly

3. these cams saw a 38 whp increase untuned through a power robbing th400 automatic tranny despite all the mathemagical formulas you want throw at them.

4. price drop to 1900 shipped.

I need more funds for the supercharger project

taking offers..... nothing reasonable will be refused, i really need these gone.

How much to ship to Australia?

holy smokes shipping would cost 550.00

im emailing you

Will 45 heads fit 41 blocks?i might be interested if these can be shipped to the UK.

email me on bizzleiphone "at" googlemail.com

Cheers

In a word... no.

Do a search, the reasons have been covered thoroughly.

final price drop

1650 shipped to the lower 48

Is there any possible way to squeeze out more power from the top end?

In other words is there a possibility of more powerful cams?

Sorry for the noob worded question.

from what ive been told these are the biggest you can run without having to butterfly the pistons for valve cleareance.

Pretty much all the power to be picked up with these will be above 3500 rpm i would guess, and they would possibly stretch the "useable" power band to 7500-8000 according to steve.

sigh....

taking offers
