aks801 Alan the carbs, throttlebodies, stacked system, retro systems all have there good and bad about them. I run a single 1,200 cfm throttle body on my car. The next motor I am building will have TWM 58mm setup, which I already have. You said you want to be original, that would but you with a Carb. IMO in the low and middle rpm range, a good FI system works better,gets better gas mileage, and responds in high "G" turns with out gas wash in the cylinders. Top end and speed a carb wins. You didn't say the magic question?
How much power are you looking for?
The trans you want to run, and rearend gearing. No body has done a carb test compared to a TWM or Dynatek 48mm throttlebodies. The webers do not flow the same as the other 2 and depending on motor size, they run out of cfm in the low 6,000 rpm range. This is also not a bad thing. You also want to e-mail Dean Lampe. He has been running Dynatek on his stroker GT-40 for 2 years. He started with webers and crossed over to the dark side, FI.
You have a private e-mail. Rick L.
