Your costs are based on info I just gave you for my somewhat stock 292 rebuild...
As always you need to consider what vehicle the engine is being swapped into...
In my situation..1968 Chevy K10 original four wheel drive 4 speed...
Is it easy to adapt the 4200 to the SM465 4speed or any older GM manual transmission and or bellhousing? And necessary modifications to the 4200 oil pan to clear front drive axles.
Do you think the 4200 makes the same or better torque than a 292 at 2500 rpm? This is important for a truck used as a truck..
