I need to replace (not rebuild) the transmission in my 64 Galaxie and I am looking at the wide ratio C6. My thinking is that with a heavy car and 3.00 rear gear the wide ratio would give me a better feel from a red light/stop sign. I am wondering if the Broader transmission would be overkill behind my mild 390. I purchased the 390 from Randy Millard and I'm very happy with the engine. Here are the specs:
Block assy:
D3TE mirror 105 @ .030 over, true flattop cast pistons w/9cc eyebrows (calculated c.r. of true 9:1 - reg fuel friendly), 2UA crank at std/std, C7AE rods fully reconditioned using ARP bolts, Cloyes double roller timing set, Melling M57 oil pump, Melling MTF-4 dual pattern cam (.486/.510, 204/214), OE "bull nose" Galaxie oil pan, late (1-1/8" thick) harmonic balancer.
Heads:
Fresh C4AEG units with new 2.03/1.55 valves, hardened exh seats, premium manganese bronze guides, viton positive oil seals. Spring pressures are 95 @ seat, 270 open. Chambers cc'd at 75. Stock rockers with new SealedPower shafts.
Induction:
C4SE iron intake with OE PCV system, freshly rebuilt 1.12 C5 4100 4bbl carb. Decent Thunderbird v/covers.
Ignition:
C4AF-N (police interceptor) distributor, NOS Autolite points and condenser, new black cap and black Packard wires, new Autolite 45 plugs.
Exhaust:
Shorty style headers with 2.5" pipes and flowmasters.
This is just a nice weather day cruiser.
Thanks for any input.
