  • Regular price $18,250.00



The Smeding 8-Stack EFI gives you the best of both worlds, the classic looks of the vintage 60's racing and the efficiency of today's modern electric fuel injection. This unit comes standard with the raw vintage finish but it is also available in a high polished finish. Don't worry about tuning because every engine comes individually dyno tuned on our in-house dyno. This unit is so clean and simple that those who are familiar with the classic Weber setup often confuse it with our modern fuel injection.
