I'm about ready to massage my engine.
My sig shows what my car has...my goal is to get into the 11's in quarter mile, 7s in eighth. I would prefer to keep L98 350 pretty much stock looking. I also prefer to use lower rpm ranges than what most seem to run...so that would mean eliminating companies like TPIS and the miniram. I am inclined to use LPE and their SuperRAm. I would drive this car regularly expect when drag racing is necessary to satisfy the urge.

QUESTION IS: With money not being much of an issue (to the brink of death by the wife)...what should I do to my motor specifically to reach my goal (Heads, Cam, Intake, Runners, Fuel Pressure, Throttle Body Size,etc.)??? If I must use a power adder, So Be It. I would have no problems changing my rear gears as well. I'm new at car crafting, and am learning constantly. I would prefer to keep stock bottom end at this time if at all possible.

Any responses are appreciated.

I think your gears are perfect already.

how do you want to be launching the thing?
are you going slicks +converter, or just driving it out on treaded tires?

it will make a big difference on how you build to get in the 11's.

It could be as simple as a small nitrous system, or many more mods.

 

Smith,

If you want to use the lower RPM ranges, you'll need a lot more stroke than the L98 has to get it rockin' quickly enough to produce decnt times. Either that, or you'll have to shave a lot of weight off the car, and a daily driver can't afford to get too lean.

If you look at some of the common formulas for HP, torque, mass, and speed runs, you'll see that the ¼ times are a function of all those factors.

You'll need over 450HP and 430 lb/ft of torque to propel a standard (3,300 lb.) F-body a ¼ mile in 11 second times. This can be done, but will be difficult to retain the daily mild-mannered driveability you might expect. If you use a power adder and/or lighten the car, the job will be a lot easier.

I will want to use street-legal tires (BFG Drag's, etc.). Anything DOT approved.
Torque Converter?...If I need it. But I want it to be driveable on the street. (My knowledge of torque converters is relatively limited. Know how they work generally, but application is hazy.
Launch?...Relatively quick. I'd rather get a jump on someone and hold it than play catch up.

400s in torque and hp is a lot. I'd be willing to "settle" for low 12's, and then juice it into the 11's. If possible I'd rather stay off the drugs. if anything, I might be willing to take it to a professional to install a turbo.

I want the car to be streetable, and somewhat undercover. Car won't be a daily driver, just one I will drive often. Lots of F***** mustystanks in ALabama. Whatever it takes...

 

btt,
to tired to post right now.
maybe others will jump in.

 

Maybe I can make simplify the question:

How much horsepower and torque can I expect to make with a 350 L98 using aftermarket parts? Cost is not an issue. I would prefer to shy away from TPIS and Mini Ram. Would probably go with companies such as LPE, SLP, Comp Cams, etc...proven, quality companies.
