Best way to proceed with improving up 427 Windsor street setup

[Pman1961]

Brent, mine and Ace's motors are very similar with the exception my displacement is 445. I had two options of cams from Keith Craft. I chose the one that would give me the nasty idle and produce peak power around 6000 rpm. The other (do not recall the specs) would have been more civilized for the street as it was less duration and I believe 110 lobe separation. My specs are as follows:

Intake and exhaust lift .609
104 intake center line
108 lobe separation

What are the durations, Perry?

I like the lift, it's where I usually am with my custom grinds. The 108 LSA will make for more torque down low and the 104 ICL makes for some good street manners.

You have around 20 cubes more than Ace, so your cam will need to have more duration to help fill the cylinders.

Sorry Brent I was in a rush to mow the lawn!!

Gross valve lift intake and exhaust .609
Duration 0.50 Intake 254
Duration 0.50 Exhaust 262
Intake centerline 104
Lobe separation 108


My cam according to the dyno starts coming on hard at 3000rpm when intake and cam start working together. I originally wanted a cam to make good mid range and top end power to keep from boiling the tires every time I hit the pedal. Car has to be at least 2100rpm to keep from bucking. Sounds great but makes slower or city traffic less enjoyable. It's not like a slug down low just less torque. I may one day tone it down a little. Aces car had nothing anywhere. We are going to check out a few things but more than likely we will be doing a cam change and I'm sure you can recommend him the ideal camshaft!!
