Reply to "Engine Modifications"

Any late model distributor with the modern large diameter cap will be very close or touching the firewall. If it touches, sharp acceleration may torque over the engine enough to cause the cap to hit the firewall, dislodging it and breaking the rotor. Bottom line: use the old-style small cap; all your listed ignitions will work fine; carry a spare brain- box or cell phone, as reliability is still not perfect. After 28+ years, the valve springs should be changed, and they should be part of an "engineered kit" sold by all cam grinders in conjunction with their cams. As far as carb & intake, one of the most popular & best in terms of performance & driveabilty is Edelbrock's Performer, which will accept a Holley or Edelbrock carb. I would not go over 700 cfm nor under 600 cfm in sizing, and stay well clear of all double-pumper carbs unless you intend to jet it on a dyno.
