Last time I weighed my formula it weighed 3800 pounds without me and 4000 with me.
The only thing missing from the factory is the air conditioning compressor ,spare tire and jack.

When I first weighed my 74 Firebird it was 3960 without a roll bar or driver. It had iron heads two batteries and two bottles. Now I've widdled it down to around 3650 with a roll bar but no driver.

So went out to tnt again sat, weather was similar to last time out, a tad cooler but more humidity, anyway track wasn’t near as good as last time since it rained from Tuesday thru Thursday night! Had a issue with my tach acting up so I couldn’t shift where I did two weeks ago, short shifting it, car basically ran same Et with worse 60ft n more mph! Very pleased with the outcome considering everything n less gear now.

With the tach screwed up were you able to see how much the rpm was reduced at the stripe? |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
