1969 L78 Smog set up
« on: May 21, 2021, 03:19:42 AM »
I have a 1969 L78 I’m in the process of restoring. There’s a seller on eBay that is selling a complete “restored” set up. Has anybody had any luck with this one? Thanks!

Diverter valves are different between a SB and a BB. The difference is slight, but if you are going for a 100% correct restoration, you'll have to confirm with the seller which valve it has. IIRC, the SB valve is 29295, and the BB valve is 29297, but I'd confirm that with someone here. Pulley is probably a repop, but those are easy enough to change down the road.

Correct on the diverter valves. Years ago, ASL in Nevada had great, correct kits for not too far south of what this vendor is aksing. There are several choices here, including PartsPlace for a couple of hundred less. If you want to piece one together nowadsya, good luck - most of these parts like the correct restored pump and diverter will set you back some serious change if you can find them. Do yourself a favor and order an inoperative kit (devaned pump) and plug the exhaust tubes - it will be easier to tune, and get away from the inherent pump problems the cars always seemed to have.

Regards,
Steve

The B/B bracket for the pump in the picture shows two holes in it on the bottom. As far as I know that is a newer bracket. I do not think any '69 Camaro had that bracket, but possibly end of year build got it.
