Edelbrock mt-5 for 318

Stainless steel allen key pipe plugs work great too. I use liquid teflon sealant on the threads.

I have access to an eddy streetmaster 318 from a buddy for free. Looks like a mini torker ll. Is this thing a low RPM torque killer? And if so, what could i use with it to get some of that back?

The plan is a mild build 1974 318 with 68 340 exhaust manifolds, maybe a set of 302 or swirl port heads, Melling RV cam. Eddy 600 4 bbl carb.
I wish I could could find a streetmaster for free! Steve Dulcich of HRM claims that these are great manifolds for stock or mild street/towing type builds, with a strong off idle to 4,500 rpm power band. It would be great combination with a set of 302 swirl port heads and an off idle to 4800 rpm cam.
