We installed quite a few at the shop years ago.All were decent motors.All seemed to run good and had no problems.They were all in daily drivers.I know of at least 2 that went well over 150K and were still going strong.Rocky

Depends on handful of miles..i would run it first..before spending money on it..but I would do the water pump... Supposedly it has like 1500 on it. I pulled the valve cover and it's spotless. Why the water pump? I am going to dress it as a mid 70s version, so AFAIK the water pump and timing cover should be the same - I was going to leave it alone. Motor is non-AC and I am using it in an AC car though, so maybe the pump should be changed.

Our experiences with Jasper engines has always been good. Jasper uses OEM or better quality parts, not cheapy replacement parts from AutoZone. Timing chain and oil pump will be fine. The only accessory to be wary of is the alternator, and only if it's a Denso unit. Awesome, TY.

i think there is a id number on the engine that their website can tell you whats in it--when it sold--they all have a warranty....

I have been inside the Jasper plant several times (I used to sell them powder coating). It is a well run organization and everything I saw looked top notch. I "think" they may sell a few hopped-up motors now, but don't quote me on that. Jasper is known for good quality stock-rebuilt engines. My step-father (40 yr. mechanic) used to speak highly of them. That's all I know... I'd run it like it is, though like Neil mentioned, I don't think they degree camshafts, but I don't think that's an issue unless you're trying to get every ounce of power you can out of it.

If you do NOT know when it was rebuilt, I would change the rear main seal. It's difficult to change that in the car, but easy while the engine is out. Already in the plans, I have to swap the oil pan to a center sump anyway.
