Welcome to the Inliners world of Buzzing 6s
If want to see 14s go look at my videos lol jk.
Anyway if you still have the stock 3.08 gears Chevy loved so much You'll never see 14s with those gears.
So questions being What gears do you have?
What cam?
What kinda compression are you running/Have
Stock cam Stock copmression stock gears and the weight of that year 70 which I know is between 3000 & 3200 lbs I know this because i have owned them all from 62-70 an my 69 SS tipped in at 3230.
So with saying that You would be Lucky to even
see high 15s let alone get out of the 16s
My 64SS Stock Motor(250 155hp) Stock 3.08s Headers Offey 4b intake with glide ran mid 18s Changed out the tranny to a 3speed Sag. dropped to Mid 17s
So my 2cent opion to you is Swap in a new cam
stay with a hyd cam. Bump up the compression a
little,Step up to a HEI dist. Offey intake small
4b Headers Or some type Of Dual exhaust. and
change the rear gears to the Very Least a 3.32,
3.55.Maybe even think about swapping to a Turbo 350 You 6 will like the extra Gear.
When I first Built my 250 back in 1984 with a 583/
607 Mech. cam Pushing better then 12-1 a 4speed
4b intake system Headers and a point dist. 3.08
gears. The best the car ran was 15.15 in 3rd. All
day long 24-7 Close to 17 yrs later when I finaly got gears in that SHOULD have been in a Long time
Ago. and the Motor showing it's age The best it
ran was a 14.3 in 3rd gear Never got to 4th. Now
If that same build had the Right gears in it from
the start the car should have ran mid to low 13s.
And Yes This/that was my daily driver. To ME. For
Most that was way to much Cam & compression for
a daily driver for many.
So any more questions Just fire away We'll be Happy to help you get close to something.
