STR12 edelbrock crossram fitment

[Illahe]

Just so you understand what a Street Tunnel Ram is - if you think about the vertical runners on a tunnel ram, stick the four fingers of both hands up in the air palm to palm in that configuration, since it is a Mopar small block pair the fingers of each hand, offset them a bit and then fold the finger pairs flat so they are horizontal. Now you know what the inside of a street tunnel ram looks like under the top plate. There are long runners and the carb on the left side of the engine feeds the cylinders on the right side and the carb on the right side of the engine feeds the left side cylinders.

This by the way is why it never made any sense to me that Edelbrock offered six pak, single centered four bbl ,and single Dominator tops for the STR intakes on Mopar RB motors.

TA heads?

I believe edelbrock has stated that the core boxes went missing decades ago and they have zero intention of ever remaking. I have one on a 410 stroker, that I initially used the dual 4 barrel fitech EFI on, but later I switched to dual quick fuel 450s. Runs great, and I didnt bother with the internal mods, I have never had any issues with backfires or anything like that.

Cause you're smart enough not to over fuel the piss out of fit.
