timing chain question

Hi, I have a question, has anyone used the LT4 timing set and drilled the dole hole for a bushing to install offset bushing to get the the correct timing. Or do I have to buy a Cloyes Hex-adjust.

You could not use a Cloyes with the stock water pump. Unless you post some mod info, we don't know what you have.

Hi OK I have 383 Lt1, using the stock timing cover and acc. The reason I am asking is I need the cam installed 4 degrees advanced.

simple solution http://www.summitracing.com/parts/MRG-988G/ by using this offset key you can control the cam timing

Hi, Thank you I did not about that. Learn something new everyday.

Ray396, I am assuming you are using a degree wheel to check your cam timing? If you do buy an offset SBC crank key, you will need to file it to match the cut-back design of the LT1 key.
I think most LT1 cams are machined with 4° advance built in. Is that what you are talking about?
