TODAY is a Great Day to visit our Store and order the parts you need for your truck!
how do you get such great mileage ? I have a 4.3 v6 and the best i can get is 18 all interstate miles. driving back and forth to work which is mainly backroads i aveage about 13.5
This is a great thread. I have a 83 swb stepside w/ 350 w/ an edelbrock carb, 5x14 K&N filter, short headers, and true duel exhaust. I'm unsure of the diff or transmission. I am told the diff is original and the transmission is a stock replacement. My big goal is for my truck to be a daily driver and of course good on gas. I was told EFI was the only way to get over 13. Im currently getting 10-13. What are the major things to check and replace to get great MPG? Also do any of yall run ethanol free? Does it seem to help?
good deal. what was the issue? lack of fluid?

What happened was the water pump weep hole was leaking----all the way down onto the trans cooler line----which made me think the trans cooler line was leaking water (and of course water is NOT supposed to be in the trans----so i thought the trans was hosed). As it turned out, i traced the leak back to the pump and replaced it with an Edlebrock 8811. REALLY not happy with the Advance Auto budget line pump, which seemed to only last about 12,000-15,000 miles. VERY happy with the Edlebrock.http://forum.73-87chevytrucks.com/smforum/index.php?topic=35709.msg301880#msg301880Trans seems to work fine.On a side note:As i did some premature research on transmissionses, because i thought i would have to replace mine, i heard that a 700r4 is the same length as a TH-350 with 9" tailshaft, and this appears to be true. So, if most trucks came w/ 9"tailshafts, then it's a bolt in swap, although the trans crossmember has to be moved up 2", or modified, or maybe there is an aftermarket bolt-in crossmember..............because the 700's trans mount location is 2" further up than the TH-350's.
