The series 1 should be considered only for something smaller like a Jeep. Even then, it's not going to knock your socks off but should give excellent mileage. They can be turned up but they don't have some of the features of the series 2 that allows them to survive at the higher power levels. The Hercs weigh 125 lb less than the 4BT so they are a viable option for smaller vehicles where that weight savings can matter. 85 HP is a number I've seen around, and 70 HP another. There are various versions and end uses(vehicle vs industrial).what are the hp ratings of the herc engines?are they good engines worth doing a swap with?
300 is a good price on a small diesel that runs good. Does it come with bell and clutch, maybe even transmission?the one i'm looking at is the smaller of the 2 do you think it would be a decent swap into a scout or should i hold out.i can pick up the engine for 300 or less maybe.worth the money?
I don't know on either count. I just know that some changes were made for series 2 and that series 2 are rated quite abit more than series 1. As I mentioned previously, I know piston oilers are one difference and this to me is a significant change in allowing more power in the series 2. I don't think the series 1 will have major problems with hard parts making the power, excepting the pistons, though I could be wrong....what kind of lifespan problems does it have and can the problems be fixed?
