Do I wait for the 5 speed?

LA 360 with rebuilder pistons (8.5:1 or worse), Mopar R/T heads, RPM intake, Carter 1406, Bullet Cams regrind (206/210 @ 0.050, 262/267 advertised, .517/.520, HR), cast iron freeflows, dual exhaust. I wish it has some compression, it's pretty mild for what it is. Fun, but I wouldn't say it has some balls. But it is easy to drive and the 1-2 shift doesn't seem to bother it.

The trans does need syncros, at least 2nd gear. Get's hard to shift into 2nd at the top of the RPM band. But it's coming out soon as I get healed up enough as it also sticks in 4th some and I want to get that fixed before I get stranded somewhere.
So We have had the same experience, just opposite opinions, I found the splits & shifting agonizing. I'd be willing to bet with telemetry, each shift took 3-4× longer, which came up pretty quick w 4.89's.
