You can make a block off plate for the EGR crap that is on the stock L20 intake. Just have someone make you one out of aluminum...or check your local JR for an older 620. Look for the year 1975-1976, I think they have a less smogged up intake.z1000e wrote:I got the webber carb off ebay from redline to fit a datsun 620 with all the goodies . can't find any intakes here so far. Is there a way to stop up or plug off the smog holes. thank YOU z1000e
