12o'clock Timing Tab
Do any companies make a timing tab for the 12 o'clock position on a small block chevy?

Don't want to sound stupid but why do you need a 12 oclock timming tab. unless your harmonic balancer has an extra key slot there's no way the "O" timing can be anywhere except at 2 oclock, unless you have a different grind crankshaft and camshaft.
again just curious Zip. |
Some sbc's had the ting tab behind the water pump at roughly 12 o-clock, welded to the timing cover. I've never seen any aftermarket tabs for that. However, if you're using an aftermarket balancer, the marks will be closer to 2 o-clock. You really should determine true tdc with a piston stop and mark your tab accordingly......

agree with johnracer..some of the later sbc moved there timing marks to 12-o-clock so you can see them..won't find any aftermarket pointers for them..about only thing you can do is get a ballancer off an older sbc.they all are at 2-0-clock then everyone sells pointers for them..

I bought an ATI super damper which Ive got to put on, Im gonna have to find TDC with a piston stop tho. The car is an 89 Iroc which origionally had a 12 o clock position. The current block and crank are from 75 but when I hit it with a timing light its showing 12 not 2

Im doing initial timing. Not sure what it was showing. The timing tab on the motor is at 2 o clock. Timed it by ear to get it pretty close. The car runs good but I know its not spot on.

I dont have the origional 305 balancer. The motor had 150k on it so I scrapped it along with the balancer and origional timing cover. Right now theres a cheapie proform(i think) balancer on there and I have a bolt on timing tab in the 2 o clock position. So what your saying is do total timing once I get the new balancer on and I should be able to use my 2 o clock timing tab?

Yes, as long as you don't have a computer that is controlling your timing.
