I just wonder what it would run if you had a good gear, like 3:73 or 3:90

it would run close to the same just at higher rpm's

you need horsepower to go quicker not gears

at the bpg in hebron ohio

i installed a short set of tires (25 inch tall)

with my gears it changed the ratio to 3.08 area

ran 15.9@84 went thru the traps in 3 gear

installed 29 inch tires and went

15.9@86 went thru the traps in 2nd gear

i drove to ohio with the short tires and was 2900 rpm's @70mph

on the way back with the tall tires 2400 rpm's @ 70 mph

now this is just my own opinion

You got it right; with a 4.11 spool I'm in the traps at 6000 rpm; with 3.33, 5200 and the 1/4 is still 12.99 - 13.04. NY IN'TL RACEWAY PARK in 2007 with my '69 225 and Guadagno 455 STAGE 1. Tire height changes were the same deal for me too; NO SOAP.

NEED MORE POWERRRRR!

I like your Wildcat; that is dynamite performance for a big car. Buick does not disappoint! My '69 225 Convert pulls 15.5s at 89mph with 'ear tune' and only 2,5" exhausts, the rest dry bleached bone stock. You gotta love it; going fast with class!!!

God Speed,

i finally broke down and got a set of the infamous 70 wildcat shorty headers

fresh with a new coat of high temp paint

004-6.jpg

had to raise the engine a little but as TA claimed a direct bolt on although

a tight fit

008-4.jpg

010-1.jpg

my new(used intake)

006-3.jpg

used poston black valve covers

I still need to prime the oil pump and button it all up for cam break in

and then i will top it all off with the gm buick chrome breather

well the nats are over

the wildcat ran very well

best et was 13.13

best mph was 103.9

average et was 13.20's

my last run i got a .006 light.......sadly on the red side........ but hey i was this close to a perfect light

next on my list is to remove the 2.78 gears(yes 2.78's)

and install the 3.42 rear add a new converter and shoot for the 12's.......

just to clarify

this wildcat is no longer stock

new engine

462 ci

10.15 to 1 compression

b4b intake

TA SE stage 1 heads

shorty headers

More horsepower and less weight are obvious, but a 2.73 rear end is a pretty darn high ratio for drag racing. I'll bet the 3.5 will make a huge difference. Surprised you are not going for a 411. I assume you have a 3 speed automatic?

yep i got a turbo 400 trans

as for gears i dont think you can get 4.11 for the buick 9 3/8 big car rear

they did make some 3.90 sets but they are real rare

it took me 7 years to find a set of 3.42's

Alright man those are some sweet numbers ya gotta help me out though.  I've got a 70 lesabre 4dr custom 455 bored 30 over hei distributor from t/a, ta112 cam, t/a stock pistons with 23cc dish, and everything else is stock.  2.73 open diff stock torque converter.  Now I can average 15-17 mpg on the highway but even crazier than you trying to make a drag car out of one of these lovely boats I'm trying to make an all around good handling stopping 1/4 mile eating cruiser.  So my question is how???? Just like you can't find any rear end help, what curve do you have on your distributor and how much of a difference did your new 2200 stall torque converter make compared to stock?

when i started i ran low 16's all stock 2.78 open rear(but did get up to 19 mpg on the interstate)

the converter dropped me down to 15.4

a posi carrier and dist re curve  got me down to  low 15's

a 1 inch 4 hole carb spacer  a 175 degree thermostat and cool October temperatures got me to a 14.58 basically all stock

 

for a rear you need to find a 67-70 riv GS (these all came with a 3.42 gears)

you can  take the carrier and gears  out and install in your rear

i found mine for 500 on ebay bought the the whole car and parted it out

or build a custom ford 9 inch
