EST..
 

Okay, I do not know what my timing is set at, i set it by ear.. :o and with what its set at I get 25 MPG At the 1/8 drag strip doing 9.3's all night (6-8runs) and even better with Highway.. best so far was 28.. Not bad for a 350 TBI. The car is pretty quik and fast.. anyway, I just want to know what the timing is set at as is. and try other settings to see if its capable of being quiker.. and maybe i'll tell you what i did to my 350tbi to get such mileage ;)

This wire here.

If i disconect it or keep it connected and check the timing, i cannot get the mark on the balancer near the tab(TChain cover). This wire does nothing for me.. I was told its the EST.. and to disconnect it to be able to get a accurate timing setting..

sounds like you need a dial back timing light

Whats that?

it allows you to set a specific timing point (a professional type not teh dollar store pos) if doing any performance tuning it's the only type to use it would be like setting air pressure with a baseball bat, it will get you something, but who knows what.

I spent 40 bucks on a POS...

that's a cheap one, a good one runs about $120 (and tends to be a bit more accurate)

good job arch. now he can tell us all what he did to make his 350 get such good mileage

simple...tbi :lolsign:

Well, i did some of these...

LOL, No kidding eh? Heck running thinner oil can get you better MPG..

depends on weight you run already, running 5w30 compared to 10w30 hasn't been shown to improve anything, but running 20w50 will decrease it

20W30 sounds like heavy duty Racing High RPM motor oil.. am i right?

yes 10w40 is a bit heavy for todays engines even, all cars coming from GM have 10w30. If you get your oil changed at the dealer it gets 10w30 also (guess what grade I use)

I use 5W30 synthetic..
