how much timing

my 540 bbc im gonna switch it to fuel injection as yall know but i run 36 deg. of timing now with a carb will that stay bout the same with injection or do i need to go lower.

 

Yes , you will stay with 36, read your plugs
as a precautionary measure though. 36 is usually a preferred choice
my alky injected bbc motor loves it..( 36 ).

 

We have had two different alcohol engines on the dyno and both make the most power at 30 degrees ? What does it like with 36 in it? I'm just curious !

 

My timing use to be set at 32 degrees, untill i started to bump it up till the plugs showed signs of optimum coloring on the strap and as a result it has good equal exhaust temps, excellent reading of the plugs, and i am puting more fuel in it with out showing any signs of excessive wear, in the filter, on the bearings, and in my pocket.
not to mention reseting its best 60 ft to a 1.19 from 1.24 and from running
5.75 1/8 mile to running 5.70 flats, pulled alot stronger out of
the whole, and kept pulling threw the top end.

What do you get for egt readings ?

 

timing

I have a 468 12.5 to 1 comp and run 36-38 at 25 boost and no prob and egt at 1150 due to the chamber on bbc you need to run more timing than a hemi most hemi guys shit when In tell them that they say 28 is a killer tune

 

my egt`s with the right jet runs 1135,
one jet to rich 1110-1120
one jet to lean 1150-1175
i run a .090 jet @ 750 -1200 ft corrected alt
and return fuel w/( larger #) jet, two sizes for every 600 ft alt increase.

 

I was just trying it on the dyno, but I have not tried to run more than 30 degrees on the water yet ? On the dyno, the Chevy showed a power loss by trying 2 degrees either side ? Maybe I should have tried 36 or 38 to see what it did ? Do you think there would be an advantage to having more timing even if it really did lose a little power ?

 

in your case i would bet the cam is playing a role
on what your motors like.
my cam spec was ,
mechanical roller , comp cam
775/748...286/294

P.S. my motors are on alcohol 14.1 comp

 

I bet that is it !
Now that I think about it that way, one is a unblown, alcohol injected Pontiac w/ 16.1 / 1 comp 292-299, 748-775 112 LC and the other is a retro 8-71 @ 25 % Dart 345 w/ 10.25 / 1 comp and a 288-292, 730-760 110 LC.

Thanks for making me use my noodle !
