Atomic Street Torquer 550 long motor.

Recommended Posts

Has anyone got one? Seen one or know much about them? They seem like excellent value at around 9500 shekels. Im doing my sums on bottom end replacement as there are  now over  250,000 reasons to contemplate a failure, and when you consider the time and extra parts needed when fitting a shortblock, and still having an old 250k head, the long motors start looking VERY attractive. Just looking at the Atomic site, geez he makes some gear for the barras.

they are bloody awesome bits of kit, but not great monetary value as they're basically the most expensive engines about (atomic in general)... their short motor for this model you're looking at is a better option, imho. With the short you don't need extra parts, just go with your existing head/sump.

that's the thing, my existing head has +254 thousand k's on it. Im thinking that when a new short motor is going in, it would pay to fix and upgrade a lot of existing components. I mean Im going to need a full gasket kit, might as well do studs, overhaul cylinder head, timing chain kit and balancer...then the assembly. Does this make sense or am I overthinking it?
