Brian,

I'm pretty sure 29" tires fit w/o major mods. The 30's require body work. I'd get the car weighed so you know where you are. These cars are like big, fat girls w/ baggy clothes...they hide their weight well.

Later,


Steve.

 

I'll definately look into it Steve. What I had planned was to dyno and then get an alignment done. A dyno should get me in the ball park for HP ( and a guestimate for what it will run and rpm) and then its off to a track. Run it and weight it. Adjust from there. If it need bigger tires I will go there but I can not see spending the money on an unknown and possibly spend it wrong. I can save a few bucks with simple math once I know the HP and RPM.

 

Brian, I agree. Don't make any changes by guessing. Tune it and run with the tires and gears you have. Worst case is that you have to lift at the 1000' mark or so. I seem to remember someone lifting at the 1000' mark and going 11.60 at 101 mph on the inital runs. Now days I only muster a 12.0 at 116mph.

 

You should see about 315 HP and run about 13.1 @ 96MPH if you hook hard.

( See should have painted the engine BLACK! )

I'm going to say with the drivetrain loss you should see around 470 RWHP, with the weight out of your car you should trap in the 128MPH.

 

 

lol, you know the block is painted BLACK!!!!

 

Not to be the lone low guess here, but I would think with the combination of the big stall, the small cubic inches, big cam, and stock ecu you're looking at around 420ish peaking right at the 7000 rpm redline. If you can get past that limiter and twist that motor higher, I'd say 475 - 500. I'd LOVE to see it hit 450 rwhp before 7K, I'm just a bit skeptical on an LT motor.

 

I made 406rwhp with a bigger converter and smaller heads and cam so I don't see why you wouldn't make 440+rwhp. Except for my 4500rpm converter, we're pretty much running the same drivetrain.
