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.
Agreed on the cam selection, it will make or break this build. That's why I haven't got it figured out yet. We all know these are high-rev motors, but I'm also realistic about how this car is going to be driven. When it boils down, I'm building a street cruiser that will be driven in the summer on city streets, with some freeway driving to car shows in the area, and maybe an occasional trip to PIR for some 1/4 mile runs when I'm in the mood. It's not going to get the chance to wind to 6000rpms a lot, so I need to build for low-end as much as possible.
Now that said, I want to be able to lay some tire when I feel like it. So I'm trying to get caught back up on all the new cam tech that has happened in the past 15 years or so.
I will be going HEI, and while I have the existing rad, the cooling system will be getting an upgrade when the build happens as well.
As for roller-tip rockers adding HP, I'm doing it strictly for the lower wear and cooler running. I want this motor to last. I've heard really good things about this set of roller rockers and am seriously considering them:
I know, ebay parts? But these guys seems to have a good rep with the builders online and I've read nothing but good things about the parts, and for not much more than stamped roller-tip I think they may be worth a shot. Still mulling it over however.
