Just another build thread - Sort my combo!

Correct... I recommend VOETOM's book on torqueflites, this will tell you exactly what you need to do. https://www.amazon.com/dp/1613253354/?tag=fabo03-20 Also, buy a torque converter from either Ultimate Converters or PTC, none of the generic off the shelf stuff offered by everyone else. This is oftentimes the make or break between an "Untouchable" or an "it's okay, but it feels like somethings missing" combination. Check out the Big block forum here, too. TTI does make some 440 specific A body headers, and at that power level, 1-3/4 tubes would work well, as would the Schumaker Tri-Ys. 10.6:1 with aluminum heads would be fine on 91-93 octane. The E Streets are rated at 1500-5500, and would work with this camshaft.
Voodoo Hydraulic Flat Tappet - Chrysler 361-440 268/276 - Lunati Power
Go with the performer RPM or a Holley street dominator intake and an Edelbrock 800 CFM AVS. If the budget allows it, a set of TFS 240 power port heads with this grind Voodoo Hydraulic Flat Tappet & Lifter Kit - Chrysler 361-440 Three Bolt 276/284 - Lunati Power
and MP single plane 440 intake would be very strong from 2500 to 6500. A competition ThermoQuad would work very well at this level. The good thing about the converter manufacturers I made mention of is you tell them your exact combination and goals and they build the converter based on your build, it's not just a generic guess based on diameter and stall speed.

Overall sound advice... one other I would mention: I've run Coan Converters and recommended them to others, always turned out good. Very high quality and efficient.

The Edelbrock RPM will work just fine with either of those two camshafts and a 3.73 gear. Should be a good combo. I have run several single planes, I like the RPM better. With the aluminum heads 10.6 will work just fine. I would go with the bigger of the two cams Garrett mentions, but either would be a good choice... maybe stick to the smaller of the two if you run the Schumakers, tough call.

The Schumaker Tri-Y headers would be maxed out with the combo, but probably just fine, they can be run with factory style power steering box on an A-body. The TTI would give you just a slight horsepower advantage but more hassle plus you can not run a power steering box.

Used to run this combo: ported iron heads, small solid [email protected] 0.549" lift, Coan 10" converter, Edlebrock RPM, Barry Grant 800+ cfm carb, 3.90 gears. No complaints... sounds good, hits hard, and streetable. Similar to the combo Garrett has put forth.

Working on my next combo! ;)
