In response to 50hotrod
I'd be very careful with the compression.
My 489 is right around 9.7 and I can only run about 15 initial and 34 or so total - and even then it will ping under certain conditions. I use octane booster instead of taking more timing out of it. The engine really wants more timing.
Cam selection will be very important. you'll need something to bleed off some dynamic compression but yet not kill the bottom end. An engine that doesn't make any power below 4k is not very street friendly (IMO). Your cooling system will need to be up to snuff.
The ignition system is easy; a simple HEI is more than sufficient, properly curved. Everything I've read says that roller tipped rockers add nothing in the way of HP.
If I recall correctly my memory is excellent. My ability to access it is not.
