Edelbrock TR5 Versus Edelbrock 340 Torker

Didn't know the rules. TR5 would be interesting, depending on the rest of the combo and proper carb tuning. But I'm curious if the LD340 gets the "vintage" weight break. What you have available is an obvious factor as well. 50 lbs is suppose to equal .05 in the 1/4. But that may not be too hard to pass with modern intakes.
