how to speed up my pure stock 305 Camaro

I haven't invested in headers yet. Still have the manifolds on with catback exhaust 21/4 pipes.

Running 4 quarts of low weight syn. oil will gain a tenth. Running 4 quarts shouldn't be a problem if you keep close check and don't let it get any lower. Remove as much weight as possible, low weight wheels, tires, spare, jack, etc.

what rear gears do have in the car?

I put a 3.42 rear gear and a posi unit

Add 4.10's

I would go with at least a 4:10 or 4:30. With the OD trans, those gears would be fine unless you plans to drive long distances on the street. your 3:42 is not nearly enough gear for the strip.

On my 95 Impala SS
It uses a 4.10 with 26 inch tall tires for racing.
Change to near 28 inch tall street tires to drive home on.
With the 4L60E tranny get near 20 mpg cruising home.

If you Trailer 4.56 with 28 inch tall slick works.
