Hey,

Been a while I haven't posted since covid for my 425 build in my 1964 F85. I had a th400 built for it a couple years ago and am now making time to swap it in. I need to get a converter for it. I've put all my specs in to chatgtp and it suggests a 3200 stall. What brand works best? My engine is a 65 425 that's

.030 over
Cam is 230/234 @.50 .496/.504 lift from Mark
Edelbrock rpm intake
HEI distributor and MSD ignition
Roller rockers
Long tube headers to 3 inch thrush welded mufflers
Rear tires are 255/60r17 so 29 inches tall

Still have the stock 2 speed and 2.73 gears in the car. So definitely a mismatched driver terrain. Was planning on a ford 9in with 3.50 gears but have had two kids since covid and allocate funds else where lol. A rear end will be next though or possibly just swap gears for the time being. Any input is appreciated!

Most recent video of the car if anyone is interested in seeing it. -
Thanks,

Cameron
