You can be sure it is a cast crank by the size of the harmonic dampner...it will be huge. I bought a 1977 MH 440 for $100.00 last year and had to race 5 other guys to get it. It came with the 727, a Thermoquad and the stock (not cracked) exhaust manifolds. The OEM starter was dead, but we bolted on a mini-starter and ran a compression test after squirting ATF in all the cylinders. The test showed uneven results, so we will rebuild it sometime down the road. With everything we got, good standard block, all the electrics, 452 heads, 727 core trans....it was a steal!!!

I have raced a 440 with a cast crank and 400 to almost 500 HP they are fine.
