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.
That would be a cool 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.
Career best 8.02 @ 169 at 3050# and 10" tires small block power.

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.

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

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.
1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27
Livin and lovin life one day at a time

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.
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.. 
Chris..

Chris..
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.
