The ports on the intake will be like STOCK factory 48 or 96 D port ports.E carbs are not a good choice for street driving,they race OK but dont seem to drive great.The reason I said the 409 carbs is you can buy after market 409 dual quad linkage.I ALWAYS run progressive linkage on the street,solid if racing.Fuel lines will need to be fabed but a EZ deal with a 3/8 tube bender and some 3/8 fuel line and a flaring tool.Tom

I have "670" Heads; "will I have to do any additional work, like Port match my Heads to the Tunnel Ram"; I am not acquainted with the Heads you mentioned.

With Progressive Linkage, will both Primaries begin to work and then both secondaries come in "next" and simultaneously?

Fuel Lines won't be a problem with Inline Tube around, they made my Tri-Power ones.

The 409 Carbs. that you prefer are Carter AFB rear 3361s and 3804s front, these numbers I got off the Internet? I thought that Edelbrock was a copy of Carter AFB, have I got that wrong?

Tom, I realize this Job has taken Its toll on you, these are my final questions, your doing a fantastic Job too, not many people could do what you are doing nor as well. Mike out.

Lucky for me I have the Scoop to help clear any height Issues, fiddling with Air Filters is my last concern.

By the way your Photo from the Plan View came in for me, very nice.

Thank you Tom for all the info. Questions answered. Where would be best place to get 409 carbs? I have mid 60s Pontiac afbs. As you said they are smaller. Would they function ok for street,response,fuel mileage.
