I bought my 58 Delray business coupe from a hi school friend in 61 and 11 years ago put a video on YouTube called "58 Chevy 409". It's a drag car I drive on the street, mostly cruise nights/car shows...4.88 gears and race gas make it expensive.
I've had my Sig Erson 990BH cam in my 409 since 1964 and it's what really woke up the 409 years ago. Turns out that it has the same specs as the Chevy Z11 cam (remember the 1st 427?) 5.65" lift, 310 degrees duration and 84 degrees overlap.
