what will a 90 sub with 350 have TPI or TBI or ????
TBI if is stock.
TBI from 87 up ( if stock )
how are they on the gas mileage ?
Suburban + Mileage? Similar to Military + Intelligence or Jumbo + Shrimp!
More seriously, my 91 350/tb1/3:42 almost got 16 once.. normally ran about 13+ in COS (a mile + above sea level). Have never seen that 15.89 ever again.. Now in the flatlands, and 4:10s with 16" tires... Getting around 12... near 14 on a great day & a tail wind.
Driving (and towing?.. down to 7-ish) style can slide the numbers Up or Down!
my 89 3/4 ton suburban with 3.73s a tbi motor and 36" TSLs gets about 9 in town.
TBI = pickups, capriece, burbs, etc
TPI = Camereo, Corvette
Camaros got TBI some years as well....
before i pulled my tbi, i was avaraging about 12-13 in town and i hit close to 16.5 highway.
