Malibu81 - 16 May 2007 08:39 GMT

have been in a wheelchair for about 10 years now and i built an 81
malibu with a 406 sbc, Edelbrock RPM heads, Tunnel Ram w/2-450
Holleys, full MSD setup, cam is crane 300 dur 510 lift, with a Pete
Jackson Gear Drive, stall is
2800-3200 th350 trans, i am currently running the stock 7.25 inch 10
bolt w/ a spool and 3.08 gears, i have lakewood lift bars also. it
gets out of the hole good with the stall and the torque of the 406
but
my friends all give me crap about my 3.08 gears. dont hear em whining
about it when i blow their doors off though. what should i do? keep
taking the crap or go to a diff gear? what will it do to my setup?
how
would the car perform, and what do ya think i am running for hp out
of
it? its a 1972 block w 2 bolt mains.

Thank You All
Brett B.

Are you happy with it ?

If your happy and you're still beating them, leave it alone :-)

You don't say what times you are running or whether you run it on the road
much.

Changing the rear will wake the car up from a standstill but might not feel
as good when being driven. I changed my '78 Camaro back end from 2.73 to
3.23 posi. It helped wake the car up but had the side effect of moving the
gears about halfway. With the old 2.73 gears, on the street I could drop
into 1st gear for passing and run upto 80-90mph. With the 3.23 I was only
able to drop into second most of the time.

Also to consider is the extra fuel, noise, vibration and wear that comes
with taller gears.

Hope that helps

To be honest my local track will not let me run on the strip due being
paralized from the waist down and me having to operate my Malibu via
hand controls, they say its a safety concern hahaha B.S. i say, isnt
that why you sign the waiver? oh well. its a saturday nite street
pounder and i love droppin it into 1st as well and rippin the tires
off of it hahahaa. im thinkin i will stick with the 3.08's until i get
beat anyway lol. any guesses as to the hp on my combo?

Thank you Kindly
Brett B
