What SB's can be converted back to HEI and carburetor?

I want to know the last year of the most commonly known SB, before the LS series.

I've seen a newer LS engine with an Carb on it, what would need to be done for distributor?

Use the crank sensor, stock coil packs and a programmable MSD box.

Or buy a GM Performance Parts distributor drive and a ford distributor.

Yup, you can easily make an LSx an old school motor. As for SBCs. You can get a carburated manifold for any of them. What I'm not sure of is if you can put a distributor in the back of the LT1/LT4 blocks. If you can, you can put a distributor in all SBCs. Not all are machined for a fuel pump though.

This came up the other day a friend of a friend asked me if I knew of any SB around, well you don't find them like we used to a few years ago, and the newer ones fetch big money up here(LSx $2500 up at the wreckers). I've never played with the newer style engines, so I told him I would post the question here knowing I would get the help I did, thanks guys!:yes:

Here's the actual adapter, then all you need is a Ford V8 distributor.

A gen 1 small block up to 99 will take a distributor and carb. The later engines use the 4 center bolts on the manifold that run up and down not angled, and the 96-99 engines have vortec heads that use a different bolt pattern altogether. LT1 and LT4 engines I think there is a conversion that involves getting a specific manifold, timing cover and balancer. Check out this link:http://www.nastyz28.com/forum/showthread.php?t=140825

The LS based engines have a conversion kit that uses a Ford distributor and special front cover and manifold.

As with the other Gen 1 engines you may need to change the front cover or at least get a timing pointer.
