No you don't.need to switch timing sets, and timing cover.
Bolt pattern is on a smaller circle with the Lt1 cams vs. the 1955 to 87 type sbc stuff. You need the correct timing set.No you don't.
If you are currently running a non-vented opti and still run the stock water pump setup it will bolt right up.
If you are running a vented opti, then you need to replace the dowel pin in the sbc cam with a longer dowel pin for the vented opti drive.
Another option is to ditch the factory water pump and go with an electric pump, which then allows you to run a standard sbc timing chain set, but you must go with a vented opti, since you lose the timing gear with the splined output for the non-vented opti.
I was told that any 88 model up sbc can would work. I was fixing to order a custom grind for the car and was skimming to see of I could find a used cam before I ordered a new one.Bolt pattern is on a smaller circle with the Lt1 cams vs. the 1955 to 87 type sbc stuff. You need the correct timing set.
I'm running a custom LT1 camshaft from LSMENG.com, it's bolted to a Cloyes double roller sbc timing set.Bolt pattern is on a smaller circle with the Lt1 cams vs. the 1955 to 87 type sbc stuff. You need the correct timing set.
Mike the last time I checked a SBC with a factory hyd roller cam was a step nose core........100% wrong.
The LT1 step-nosed cam has a smaller bolt pattern then the standard non-stepnosed cam.
You can run the old style cam, but you need to switch to an old style timing set.
