'85 302 HO (carbed) crate (B303) going into a '29 Ford Sport Coupe smoothie needs an inexpensive, clean look distributor/ignition. Looking at: DUI's custom "HEI"; MSD's "Ready to Run" and; Proform's "Ford HEI" (cheapest). Do these require an ignition box? Pro and cons? I'm running a T-5, no(AC,PS), manual (4w disc)brakes, '74 Vette IRS, no computer. Please advise.
