Does anyone know if jasper does anything special to the engine when they rebuild or do they use stock parts? what power do they have?

 

the only thing i can say about jasper engines is that i do not know anyone that has ever had any luck with them.

 

Have heard info to the fact they use 6.9 blocks to make 7.3s by boring them out.... good idea, but they are not too upfront about it to my knowledge......

 

we had an explorer at are shop that needed a motor so a jasper remanned 4.6 was ordered. put it it and a month later it comes back for running hot. the motor came apart and found that the water port from the passenger side of the block was not cut out behind the water pump so no water flow to the right side.
