With a 3500 stall converter on a 400, you will have no difficulty with the 292h. I ran way more overlap on my 400 cams and had no difficulties other than requiring an add on vac can for pwr brakes. When I switched to a cam with a narrower (110) lobe seperation angle, the motor did not have the big charge through the midange and the et dropped a tenth. A 400, especially with small heads will need an lsa of 105-106 to be happy. Choose your duration to suit the rpm you want to turn. also, like many others said, a flat top 400 with 64 cc heads will likely be 11:1 or more.
So much to do, so little time...

the effect of overlap on the brakes ect. will change depending on where the cam is installed
Its hard to move forward if you have a closed mind,

Here's the facts on that Camshaft.

I ran that cam straight up for 10 years in my 70 Monte Carlo. 11:1 406 sbc with old original out of the box Trick Flow Twisted Wedge heads. It ran the brakes fine, sounded pretty tuff too. I would run on pump gas as long as you kept the timing back. I put 11.5 pistons in it and it needed a bit of race gas mixed in then, at 34 deg total. It didn't pay to rev it past about 6300, it was done. It did 365hp@6000 /379tq@5400 on a Dynojet Chassis with an Edelbrock 750 and RPM intake. I would say with the right carb and intake you could get it close to 500 HP flywheel and extend the curve up a bit. I used anywhere from a 2400 to 3200 stall over the years and it did the fine in that range (4.10's) It was a 12.2-12.4 @ 108-112 car with that setup (3700 lbs).

Worked great for what it was, and I wouldn't hesitate to run one. It would idle at 700 RPMs, but it was about to shake out of the car at that point.

I can dig up some chassis dyno's it it would help you.
