Re: reverse flow 350v8

I don't think it's that hard to do. Time consuming yes. All you really have to do to make it run is revise the cam so the former intake lobes are timed for the correct exhaust timing and do the same to make the old exhaust lobes work for the intake events. The engine would still turn in the same direction. Getting a custom cam ground would be the trick. Use small valve (intake side) heads to start with and there is probably enough meat in the head to resize the old exhaust valve (now the intake) to a larger size than the "new" exhaust valve.

Cooling is just a matter of doing the plumbing as this guy did. Spark is another issue, but I think he could have used a regular distibutator, but the cap might need to be wired up differently if he changed from the conventional firing order (dictated by the cam). All, this guy used is a belt driven MSD distributator, probably done since he didn't use anything like the intake to bolt the distributator down too.

Like others have said, its not a new concept. Hot rodders have done this for years on Flathead fords or converting straight 6's with intake and exhaust ports on the same side to a Crossflow with intakes and exhaust ports on opposite sides.

By the way, that engine is definately not a LT1. The timing chain cover is different on LT1 (has a higher peak in the center for the cam-driven water pump).
