this makes me want to supercharge my IH 304
-
what are the hp/torque specs on this motor
-
the 345 is the logest lasting and toughest v8 i have ever seen. i have a 1972 IH stepside 1/2 ton with a 345 and has 506,985 miles on it!!! thats half a milion miles and still runs, starts, even in the below temp.
-
these were designed as low rpm high torque truck engines. they are best to use at 3100 rpm or lower and geared low. This is the worst possible engine type to use as a blown high rpm motor. I have a 1976 IH loadstar 1600 truck and it has a 345 motor. its basically a tractor motor. Making it do this is strange, unusual, and a waste of a good truck motor. this video is what chevy engines are made to do with, not IH.

Damn.....

345's are tough. I will take tough over HP any day when my truck drives out the end of the trail without breaking down!!!

I'm in love.

@harddrivin1le I don't know why the "dog" opinion, I've driven these 345s and 549s in trucks , scouts and pickups, and I've found these engines to be tuff and reliable!

Those engines were DOGS and were ridiculously heavy.
From the factory, the 345 4 barrel (5.6 liter) V8 with dual exhaust made 150 SAE NET HP and 263 SAE NET FT-LBS of torque.
While MOST of the IH V8s did have high nickel content blocks and forged internals, they were designed strictly as truck engines - for longevity purposes.
These engines have LOUSY cylinder heads, incredibly inefficient chambers and very heavy rotating and reciprocating masses.

A thing of beauty is a joy for ever!!

I have heard that IH motors had more nickel content in their blocks than most makes, so they are tougher than the average American V8 of the same period.
