I run a 61 Bel Air stock stroke(3.515) engine. The engine was built several years ago
to run IHRA G stock. 422 cu. in., single 4 barrel, 11:1 comp., .439 lift camshaft, unmodified 583
cyl. heads, stock assembly weight, 5/64 rings. The car weighs 3750 w/driver, stock front and
rear suspension, aftermarket control arms in rear, 4-speed Jerico. The best run was 11.49/114 mph.
A few years ago I joined the Nostalgia Super Stock group in which you must run two fours or
three twos. I replaced the .439 cam with a small mechanical roller, changed the valve springs
and retainers, installed a out of the box Edelbrock intake w/original Chevy Carter AFB carbs.
Earlier this year I ran a best of 10.60/125+ at Union Grove, WI. I think the car will run 10.50
with some other changes.
Stock stroke 409's can run quite well!
