950 horse at the flywheel, Domingo. How about a milenium headed 572 aluminum Hemi?

572 B1, 572-13, as stated 950HP, giving the suspension could hold it.

Piece of cake
512 c.i.--MP World block, 4.380 bore--Indy-1 CNC heads--13 to 1 CR, [Zero deck flat-tops should get you there]--STX-22,[276-.590] Racer Brown solid lifter cam--160# seat, 375# open valve springs--1150 Gas Dominator--Callies Dragon Slayer crank, 4.25 stroke--Oliver or Compstar rods--Freshin it up after 1000 passes. They claim the World block will go 4.600 bore, so it should last a lifetime of freshin ups.

Many different ways...
Low deck 498, Indy SR's, 101 mm turbo...
Race block stroker small block, Indy 360-1, 101 mm turbo.
Gen III stroker Hemi, 101 mm turbo.

Hello,
My pick would be large cubes like has been mentioned and then I would pick the head/cam combo that provided the best valve train reliability for the long term buck.

Well on Caltracs with a TF I am gonna say have fun
Having said that obviously weather conditions play a role. I mean running 8.99 at 0' DA is a lot easier than doing it at 4500' DA is. My Cuda was a high 8 second car in Northern CA with about an 880HP Hemi. But it is a fairly good working car. However bringing it here to Vegas transformed it into a 9.20 car pretty quickly. The same car now weighs a bit less at about 2920 and can go 8.30's here in Vegas on a good day. It now has 180 more HP than it did then.
Another way to look at it is the better and more efficient the chassis is the less HP it will take to get the job done. Just look at the Super Stock guys. Very efficient chassis and geared to the moon for ET not MPH. A car like mine is chasing MPH more than ET. I am still under geared and using a tight converter to chase MPH on the stop rather than ET on the track. In an SS or Comp type car you can likely run high 8's with 800ish HP properly geared.

800hp and a car that 60's 1.23 to 1.25.I know 2 that do it one is 3000lb camaro and the other is 2800+ mustang..both made 800hp give or take 10.A small block is 100lbs lighter.

I agree.....
If it takes much better than 800hp, a 1.25 60ft and 7800/8000 cross rpm, it needs a better car and converter.

Re: what engine would it take to put this car on the 8s? - 01/14/14 01:39 AM
In good air it needs about 820 hp to go
8.9@151. This is assuming the chassis is dead on. Better have a good converter cause 5% slip is about 7900 rpm w/33"&4.88. Weather gets below perfect, more HP. Track less than perfect, more HP. Car less than perfect, more hp. my bet is you want closer to 900. I'd say a good set of ported -1 Indys, dominator,
280@.050 roller the more compression the better. Cu in? How tight do you want to twist it?
512@8200-572@6800, either will get you there

I was going to say 850 hp. But 950 would do it easier. My 528 hemi made 850 hp on the dyno. I have run 9.88 Et @ 141 mph in my 3950 lb 71 hemi cuda. That is with a tight street converter on caltracs. My 60 fts were terrible but I didn't get to dial the car in since I don't have a roll cage and they asked me to slow down or leave.
A true 850 hp or higher will get you there.

One of my little 358 R5P7 engines with a torqueflite. Maybe with a glide and a perfect converter. You are stating your car is 2,900. It will be lighter with one of these engines too.

Re: what engine would it take to put this car on the 8s? - 01/14/14 03:20 AM
.030 over flat top piston 440. Pocket ported Edelbrock rpm's. .640 lift flat tappet cam. M-1 intake and a dominator. 2 stage nitrous system, hit it with 225 30 ft. out, then stack 175 on it when you shift to second. With that much gear in the car, you will probably have to lift off the 2nd stage at about 1100 ft., but it will pull hard enough in the middle to get you an 8.90 at about 145.
Since you saved so much on the engine, you will be able to upgrade the converter a few times until it can handle the abuse.

I plan to take this route and spray a little. Just one last LA motor and then it's all going away to start the swap

After thinking about this, I over shot big time...
My motor, which is a stock block with home ported Eddy heads, 389 inches, .520 hydraulic cam would run mid 9's at 2900 lbs. To lose the additional .5 seconds, all it would take would be a race block, slightly bigger cam and 88 mm turbo...

I think all I need is an old school blown HEMI!
I have some parts to build a HEMI (world megablock, 4.375 bryant billet crank, milodon gear drive, ray barton rocker system)
I also would like to run on pump gas and stay reliable...
Seems my best option would be to step up and build a Street Blown HEMI making over 1000HP. I hear its easy with a big cube HEMI while still being reliable and running on pump gas....
I would also not need to go crazy with the heads with CNC porting and all of that....and that would help offset the cost of the Blower setup.

I thought I already gave a cheap easy route to success. If you need to tell your friends you have a big block or power adders to run 8's so be it.

Re: what engine would it take to put this car on the 8s? - 01/14/14 09:22 PM
Thanks for all the replies guys!!!
Seems there are many ways to get it into the 8s, but I have the HEMI stuff already and I wanna use it on this build.
I was thinking NA pump gas HEMI, but to make the numbers needed on pump gas is kinda shooting for the moon and hoping the best.
It could be done, but with more exotic parts like Millenium Heads, en even bigger crank and then also I might have to run a really serious cam....due to my location its not practicual to build a high manteniance engine.
I think a mild Old School Street Blown HEMI would get me where I want to.
Lets see what happens....

I don't think it would need to be as radical as you think. My hemi is pretty mild and has been 9.50s at 3800+ lbs. At 2900 lbs I think it would dip into the 8s, or at the very least VERY close to it. Wouldn't be too hard to get some extra power out of it if needed.

Guess I will take a turn being the stick in the mud here. Running an 8 anything is not as simple as some might be lead to believe. In my years doing this stuff I have seen more than a few pretty good car guys not make that goal. Not saying it is rocket science either but it is not as simple as making a car a 9 second car. The faster you get the harder those incremental gains can be. Accordingly the more important every part of the car becomes. Just saying for the average car guy it is not as simple as one might think. IMO have MORE power than you think you will need will help but you have to know how to use it as well.

Re: what engine would it take to put this car on the 8s? - 01/14/14 11:39 PM
Well said Al..
That was my goal..I told myself I wanted to run in the 8's with N/A small block with cast manifold and single carb at 3100 pounds 10.5 tire..and I finally achieved that back in 09.
Its very hard to get that 8 sec slip.I have my first one framed

Your right Al... lots of power is one thing... but
chassis, chassis, chassis... if it dont hook you can
put over 1000hp to it and not make 8s... I'm high 8s
in my car with much less power but my car is lite
and the chassis works great

Re: what engine would it take to put this car on the 8s? - 01/15/14 01:40 AM
This is gonna sound like i have a huge ego,but its actually quit simple if you have a good car.900hp to go 8's at 2900lbs is a kinda laughable.
The car is most important..take Brian smith 408Stroker & his car runs mid 8's in Texas air no prob.
I'f the car takes anymore then 800 it's cause ur in Denver air or the chassis isn't right.

Re: what engine would it take to put this car on the 8s? - 01/15/14 01:56 AM
One thing to remember though is when we say this car ran an 8 something or my car ran a 8 something we are usually talking about OUR best run in the BEST air. Heck we have a few members you never even hear from all year till Fall or Early Winter when the "new bests" always come. All the power in the world won't help unless you can harness the applied HP to the track surface successfully.
I've seen a lot of big inch supercharged Mopar wedges and Hemi's run 9's, 10's, and even 11's.

Im still at 2840 lbs and no where near 900hp. I guess the 1.18 60' helps some. It will be even quicker this year....

Brian, you may want to re think that..
Your HP computed from your vehicle ET is 799.81 rear wheel HP and 888.68 flywheel HP.
That is based on absolute sea level conditions..
So, in Texas I'm guessing 1.05 to 1.1 correction factor..
That would be anywhere from 932 to 975 hp..

My best times are at -400 da. I assumed I was around 830 flywheel hp.
Just know that everything has to work well together. There is no magic single part.

If you want a blower motor build one but I think it is much easier and more streetable to put that money in the hemi heads and build a pump gas motor. My hemi is only a 528 with 10.4 compression. I am running ported Stage V replacement heads. I ran 9.88 @ 3950 lbs with more ET on the table. If you take the rule of 100 lbs equals a 10th of a second your car would easily run mid 8's with my motor in the car.
If I were to build a blown hemi I would be shooting for 1500 horsepower.

My 572 pump gas motor went 9.11 @ 147 with 1.26 60ft at Atco, ran 9.20-9.30 all summer long at LVD. car weighed 3280 lbs.
604 millennium motor 8.46 @ 163 with 1.32 60ft. at Atco and Englishtown. car weighed 3160. The formula of 100 lbs. per 1/10 doesn't work so well when you start going faster so I don't think it will be an easy mid 8 sec. combo.
If you take 300 lbs. out of my 572 combo and remove the 4 mufflers that I run, it should get you in the eights. We will find out soon because we are putting the 572 in my brothers car and it should weigh in at about 2850 or so. I made a lot of changes on my car this winter and removing 280 lbs was one of them. I don't expect to run 8.20's.

True enough, we went 9.19 with my brother's AMX in 1997 with a 906 headed 451 and a single stage plate. He's had a 504 Indy -1 since then and went 9.40's on motor but every time he added nitrous it failed to get in the eights. The problem was he never upgraded anything else! The car had a low 9 second fuel system, ignition, shocks... it takes the whole package.

I tested a theory on Wallace race calculators. The 100 lbs per 10th of a second is still pretty accurate at these ET levels. In my experience it is a lot easier to get a light car to perform that a heavy one.

Re: what engine would it take to put this car on the 8s? - 01/15/14 08:18 PM
Having put a few cars in the 8's or better I had no idea it was as easy as some think. I also do not think the 100lbs is a tenth is applicable when you start running 8's by any means. As preciously stated it just does not seem to pan out. HOWEVER I have seen engine combos go from a door car to a digger and they seem to have that math work a lot better than just dropping 200lbs from an 8.70 door car and running 8.50's.

I hear you but those calculators are more for entertainment value to me. those calculators say I should have a 1.13 60 ft not 1.32 like my car does. I still have plenty of chassis tuning left but still wont ever have a 1.13 60 ft.
