Hughes stroker cam recommendation
It is a automatic. A518. Cruising will be at 60 mph here on interstate. With 26 inch tires i came on 2400 rpm(out of the head, it was a while ago) stall is about 2500.
my math says 60=2093rpm in loc-up with a 26" tire. and 65 =2267.

My 367 cruises 2240 with a 230*@.050 cam, and fuel economy is atrocious. I attribute that to two things; 1) 2240 is right on the edge of becoming efficient for my combo, and 2) My cam has only 105* of power extraction by the advertised numbers, which leaves a lot of unused energy still in the exhaust when the exhaust valve opens. Energy which could have been used to propel the vehicle.
My previous cam had 5 more degrees of power extraction and 10 fewer degrees of overlap, and it was lightyears ahead in the fuel economy department. And I could cruise it down at 65=1588 where it still made excellent fuel economy. My Scr is right around 10.95, and with the smaller cam, was 10.7.
With your longer stroke, I realize that you can run more cam without driving your Effective stroke as short as mine is, but 238* is really pushing it with a roller cam (mine is a FTH). So if hiway fuel useage is important to you,
I have to agree with Rumble.
With alloy heads you can run a lotta cylinder pressure without running into detonation. Some FABO members have reported a tic over 200 psi still on pump gas. I myself am or have run 177 to 185psi on 87E10, at 205*F Minimum coolant temp, with tight-Q.
Good luck!
