Well, I had Bob Bendtsen's Transmission (the guy who makes adapters for nailheads with a dynaflow to mate up to more modern transmissions).
After I got it, it seems the engine has to reach a high rpm to get moving. And that in gear it seems to search for gears when accelerating.
Well, I had Bob test drive the car today,and he thinks it's normal. For me ( who's had the car since '83), it "feels" like more slipping than the leaking dynaflow he replaced. After talking about rpms, he hooked up a tachometer while we were test driving it. The tach read around 2200rpms at 15 mph. He then said he put a 2000+rpm stall converter in it. Shifts did occur around 2200+rpms. Yet, for me to get going from a dead stand still, it's like there's very little positive engagement. When he was driving it, he had the throttle almost to the floor. He then said there could be fuel starvation (not true the engine runs great), and what I'm hearing is the flex-fan ( yes, I know this makes more noise than a clutch fan; the flex-fan has been in there since '92, and I know how the engine sounds under all kind of conditions. I also have a '73 Riviera GS stage 1 with a flex fan and a '76 Riviera with a clutch-fan. With both of those cars, there's a positive engine to transmission engagement, smooth shifting and in the '73, there is a flex-fan roar that I'm fully aware of.
I know the '63 thoroughly--- how it responds, the engine, the old transmission. I've had it since '83.
We agreed that he would have a different stall converter (~1500 rpms).
Has anyone else had experiences with Nailheads and 700R4 transmissions?
