Make the motor either a 512 C.I., 4.250 stroke with a 4.375 bore, or a 518 C.I. 4.300 stroke same bore size as the 512. Shoot for 10.5 to 10.8 to 1 compression ratio for 91 octane pump swill and work on the rear suspension to make it hook anywhere and go have fun. My 612 HP 512 C.I. pump gas motor in my 3450 lb street Duster ran [Email]10.69@124.+[/Email] MPH through the muffs first timeout That was with ported 906 iron heads, I swapped the heads to a set of CNC ported Eddy RPM and the car ran 10.49 at 127.+ MPH. That was on a set of 30.5x13x15 M/T ET Street bias plys tires The last time I raced it it had a set of Indy SR M.W. heads and intake and ran 9.993 at 134.+ MPH through the muffs on straight Oregon 91 octane non ethanol pump swill You can get the same results also

This last part here Cab gives me hope going from my rpm`s standard port to a max wedge port............

Need to know more about your goals...

Do you want a big, loud thumper that sounds intimidating? If so, motor only, but prepared to lose some driveability and have some maintenance.

Do you want med sound with that whine sound? Supercharged, but you will still have some maintenance.

Do you want quiet and unassuming? Turbo. And very little maintenance because you can run a small cam, not a lot of gear and converter and the turbo will eat a lot of the exh sound.

---

TURBO hands down! For a true street car, nothing beats having GOBS of power, a very streetable rear gear that lets you cruise anywhere, and a very unassuming sounding car (helps with cops and for cleaning the clocks off the ball washers who think they have enough lol).

You say 10's are all you want...and yes, N/A will get you there...but you will want more...thats when you will wish you had a power adder. And when it comes to all around streetability, you cant beat turbos imo

Good luck with it!

I doubt you could build a low deck, stage 6, motor with the proper sized turbo to only run 10's. It would probably do that on 4psi...lol

If you want a 10 second turbo a body, you don't need those heads, or a stroker.


A 400/383 steel crank, Eddys, and a 80mm t6 turbo will give you 9 second pump gas capability easy. On race gas or would make 1000hp pretty easy.

Yup, also. Save your money on the heads and stroker part. Look at what we (the turbo guys) run for parts and we are very mild and in the 9's.

I have Eddy heads on a 389 sb with a .520 hydraulic roller, 3.55 gears, 3000 converter.

I think dizuster is running a similar setup.

Turbo would be my vote but...if you are going to run E15 fuel I'd just go N/A. E15 is a pita to tune on and every tank your specific gravity changes. I loved my turbo setup on non-ethanol 93 but when it wasn't available it caused problems. That's the reason I ditched my turbo was fuel inconsistency got to be an added aggravation I didn't want on a street car.

Thats when EFI comes in real handy.. let it take care

I am an All Motor guy, but Nitrous sure is a cheap way for quick horsepower. I have enought Nitrous laying around to nuke a small town. Can kind of see the 17 bottles on the right. But boost is the ultimate wat to go in the long run. Got a pair of those too for my big build when I to it someday financially.
