Man , I only see 4 4.9 Caddy's listed. I'm wondering what mine would do. Hopefully will get a run done sometime. With all the talk about the 4.9's on the Forum , I figured more would post numbers. Kinda want to see how a stock 4.9 compares with the rest of the crowd.

What RPM is your converter flashing at? Im thinking if it was higher you would see a better 60 foot. Your tranny has a "shift" kit im assuming.
By "flashing" do you mean stall speed? It is set at 2100rpm for a stall speed. The shift kit just makes the shifts quicker but doesn't change when the shifts occur. I think the 60' time may also be the jets in the carb. I'm still using the .51 jets so it seems to be slightly rich at the low end. (New jets are on order, actually it's the entire tuning kit. )

well I guess I can be added to the 15 sec club. 2.8L V-6 Mods are bored .030 over, 9.7:1 comp. Fully ballanced and blueprinted, 3 angle valve grind, .423 lift cam, bre TB and match plenum, Sprint manifold, MSD blaster Coil, K&N drom in filter, SI stainless performance valves, and Borla exaust.
Cool deal Darth! Great times. LILDevil just added an intercooler to his and ran 12.26@112mph in 90 degree weather! He should be in the 11's when the temps drop!
BTW, I will update the list when I get time, I must sleep now, 12 hours at the track without a car SUX!
Yea, I pulled a bone-headed move and didn't think to take a chip along with any more than 20 deg of timing. I was running 18 on the street but with the octane boost I was running 20 deg timing and 15lbs of boost with 0 KR so it could have been pushed a little more. Even that 1.784 60' time was with a little wheelspin launching at 2lbs of boost. I tried launching at 6lbs but I blistered the tires and came off the line sideways. I am thinking some drag radials and more timing should yeild a couple more tenths but I really want a cam because my MPH in the 1/4 is a little low which is telling me I am not making the HP I would like but the TQ is definately there. Still tho, 1.784 60' on 225 55R16 BFG Traction T/A's is not bad at all. These are definately the best street tires I have ever used.

Wanted to share the times of an impressive 84 SE "sleeper" that raced at the WheatStock Drags today. The times were witnessed by multiple forum members and I captured his best run on video. The owner is not a forum member yet but he said he would join soon.
Owner: Ralph Degenhardt ( works as a transmission mechanic) Location: Heartland Park Raceway , Topeka, KS Date: 6/26/2004
Car: 84 SE Notchback Engine: 4.3 V6 with cam, Vortex heads, 500CFM Carter AFB carb, homebuilt 1.5" headers Trans: 4T40 with 2100 stall, modified clutch packs, 3.06 Final drive Tires: 215/60R-14 Street Tires ( Mud and Snow rating...NO KIDDING)
ET: 12.504 MPH: 107.94 60' 1.783 sec.
Car was very plain looking but ran exceptionally well...
NO nitrous, turbo, blower, or racing gas. He drives this thing on the street almost daily.
His performance makes him the quickest and fastest naturally aspirated V6 Fiero that anyone has reported. There isn't another naturally aspirated V6 that is anywhere close to these times and speed.(12.50 vs.13.80's....)
