Emission crud

<< < (2/2)

Cliff Ruggles:
Test the VA with a vacuum pump.  It should start around 7-9" and all in by 11-13" or close to it.  If not get a different unit.
No need to limit it to 10 degrees, those pathetically "low" compression engines with tiny retarded emission cams like a LOT more than that at light load.

I use one here that's perfect for HEI's. They aren't on the website but we sell them separate from doing a distributor build........Cliff

Pav8427:
Thanks Cliff. I will call the shop when I get a chance. I appreciate all the good advise.

Doug
