Took my truck out for a ride today with the added timing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

All I have to say is...WOOOOOOO!!!! The thing pulls NOTICEABLY harder! For some odd reason, now the idle speed screw (the one that adjusts the throttle plate) actually REALLY affects idle speed. I turned it like a HALF turn and it adjusted the idle down to 700rpm in drive. WORKS FOR ME!! I'll report back on the gas mileage.
Thought I'd post about this, since it's the first time I've driven the truck in about a month.

nice.. timing makes a massive difference in how an engine runs.. how many degrees of total timing are you running now?

TIMSPEED · 08-06-2004, 04:22 PM

Hahah, hey Colin, didn't know you were a member HERE too.

I WAS running only about 28º total, but I upped it to 36º.

ColinOpseth · 08-06-2004, 07:44 PM

yeah, it should be around 36 total.. 6 degrees makes a huge difference

Yeah, I've been a member since like 2002 but haven't posted much. I used to post quite a bit when I was working on the restoration of my 70 CST big block shortbed

Do you still want the C4 doors?
later!

36 - 28 = 8 but who's counting?

36 degrees, thats it? bump it up a little higher

Its no fun until you bump it up to where you cant adjust the idle w/ the idle speed screw... THEN youre makin power.

LMAO... man, now you know why I changed from a Biology major (too much math) to English..

I typically adjust my timing until I hear ping then back off 2-3 degrees with my timing light..
