340 build help - 05/09/23 07:51 PM
I’ve tried searching before posting so I apologize for asking possibly a redundant question.
I feel like I try to finish this thing about every 5 years, it’s crazy how time flies…Here’s the build, I had an issue and spun a bearing had a friend helping with the rebuild and life happened and I moved to a new home and just never could get back and finish this but I have another good friend who is helping motivate me to finally finish this thing and get my car on the road after probably 20 years of sitting.
So here’s what it have, my buddy thinks I need a single plane intake and a 750 double pumper carb possibly (he is not a fan of the avenger 770) and he is recommending a better torque converter. So my questions what don you guys think the best intake and torque converter would be for this combo.
71 Challenger RT/Formal roof option(SE):
- 340-4bbl 727-auto
- Holley Avenger 770 carb
- Edelbrock Performer RPM dual plane intake
- 1-5/8" ceramic coated headers
- 8-3/4 sure grip 4.10:1 rear end (489 case)
- X-Heads machined & assembled by Herb McCandliss
- Mild port work
- 2.02-1.60
- Mopar Perf hydraulic rocker arms & springs
- Stainless steel valves
- Bored .030 over
- Steel crank
- Mopar Perf purple shaft cam 284/484
- Keith Black Sylvolite pistons (11:1 compression)
- Standard rods (shot-peened)
- Speed pro rings (file fitted)
- Double roller timing chain
- Miloden high volume oil pump
- Electronic ignition
- Light springs in distributor
- 8mm Morroso plug wires
- High fire Mopar Perf coil
- Fairbanks 11” street action torque converter
Thanks for your help in advance!
