2015年2月12日 · the 345 is basically a diesel. low hp. high torque. low rpm. you can gain hp by letting it rev higher. big block chubby valve springs. over bore it. new cam. honestly. a simple rebuild will go a long way. the pistons are high quality and fairly cheap. get high quality rings because your cylinder walls are high nickel content and extremely hard. deck the heads and block because new head gaskets ...

2008年7月2日 · IH made several sizes of V-8's, 266 which not many parts are available for anymore, 304 & 345 which were very similar, were popular and all parts still avail. 392, coupe versions @ 475 or 478, and the big dog was a 549.

2007年2月22日 · Was the International 345 V-8 used in several truck models? I was told that the 345 V-8 that is in my 78 Loadstar 1600 is the same that was in the Scout, Travel-All and Pick up. Is this true? If so, this should make parts easier to get. Was this engine ever used in a IH tractor? Could it easily b...

2008年4月21日 · The IH SV series V8's (266,304,345,392) are stamped with the engine size and serial number on a flat pad on the upper right hand side of the engine block. It's a little difficult to find if you don't know quite where to look. Here is a good page of information and pictures of where to look. IH ENGINE ID GUIDE

2020年5月11日 · I had a 68 F1800 Loadstar years ago. It had a 345 with a 4 barrel carb. The guy I bought it from had bought a new or rebuilt 345 short block. Since the truck originally had a 392 with a 4 barrel, the guy installed the old manifold and 4 bbl carb on the 345. At least that;s the story he told. DWF

2012年8月14日 · Even the loadstar trucks that had a 345 still used a two barrel carb. Alot of the power is having the timing down perfect and carb set really good. I once heard few guys with their scouts set the two barrel just right andhelps having a light foot on the gas get around 16-18 in city and around 21 on highway.

2008年9月14日 · I've had a couple of those in IH pickups and they really do run well. I also like the fact that there aren't any gaskets below fuel level to leak and you can change jets without a new bowl gasket. I'm sure you already know that, though. The used manifolds are pretty easy to find since the 392 and 345 both used the same one.

2014年3月18日 · According to Holley's flow charts the 392 requires less than 380 cfm. I've been the 345 4bbl route on a scout and will not do it again. Almost impossible to get it dialed in right and wastes a lot of gas. IH engines are slow running engines and don't require a big carb. Remember a 345 is rated to only turn 4000 rpm. Eason

2008年12月14日 · The inner edges of these bolts are apx. 9" apart on the 345-392 while they are about 8" apart on the shorter block. I can just span the 9" with my thumb and little finger for a real quick check--obviously your results may vary! Some 345's in the Scout and Light Line used the Quadrajet 4 barrel--not all had a 2 barrel.
