0-60 MPH 21 seconds? If so, that engine is worn out.
My moms stock 73 4 dr Nova, 3.08 rear gears, powerglide ran 21 seconds in the 1/4 mile 3000 FT altitude track.
Adjusted the timing, got it down to 19 seconds in the 1/4.
Non of the two 6 cyl cars I had used a flame arrester. 73 Nova, 69 Camaro.
They used a filter just on the inside edge of the air cleaner assy.

The old carb was 26 seconds, so I'm 5 seconds faster. With this carb and the retarded timing (2 btdc) leaner mixture was also 26 seconds. Maybe if I go 10 btdc, it'll drop to 20.
For the breather, the original intake has a metal screen. I see Tom Lowe's offy valve cover with a couple of breathers venting to engine compartment. Thoughts? Mark
