Firstly:
I know I should ask Hughes.
I did.
But they can't deliver because they don't have any hydraulic flat tappet cores. And there's not much choice in stock.
Same with Howard's.
Maybe someone here has an idea?
I'm looking for a flat tappet cam.
I don't like the noise the roller cam makes in this engine.

I'm looking for a lot of torque in the lower to mid range.
Street use, no racing.
But of course I want to get the most out of the engine.
The engine is a 400/470, 3.915/6.35, 10.7:1 comp ratio.
TF 240 heads. Low deck dual plane intake and HP exhaust manifolds.
Vehicle is a 1966 Charger, ~ 3700 lbs, 4-speed
gear ratio 3.23 or 3.55 (freely selectable).

Maybe someone has a similar setup and an idea?

Thanks!
 
I have a 66 too... built a 440... and put this cam in it. They make the same one for the 400.

I stroked it and then put 240's on and then popped this cam in... and then put 1.6 rockers in.

Granted, I'm going to be putting in a solid roller here shortly... but this is what worked for my stroker.
 
Do they have flat tappet solids in stock? My friend Paul is running a solid, I think over 250 @ 0.050 in his 470? stroker.
I still have the fairly large Hughes hydraulic cam sitting on the shelf that I bought from GTX John. I don't recall the specific size, but I think around 250 @ 0.050" intake duration.
Found the for sale post, 2023. The cam is the HEH-4650.
