318 vs 360 Rebuild...

Thanks @rumblefish360 ! my notifications have been a bit wonky lately with it saying i have messages, and then not coming up, etc. so i appreciate the TAG! or I probably would have missed it.

The aluminum headed 408 is LA based, and uses LA edelbrock heads. So LA intake is required.
the iron headed engine would require the magnum intake (Both of which we sell also)

On both, The harmonic balancer requires the magnum balance weight (most go with the pro products damper, although i am in the process of having my own damper made in the next few months)

The rear is LA360. take care to
1.get a quality torque converter matched to the engine.
2. make sure you go with a neutral balance converter, if you're doing an LA balanced flexplate.
(had a member recently buy the LA360 B&M flexplate, and then order a converer with weights on it.... so just make sure you balancer one or the other, but not both.

I have never seen a set of magnum specific headers. Any LA header for an A body should fit either of these 408's.

The above info is current as of 11/10/2018. I have some REALLY cool things in store for our mopars coming in the next....approx 6-12 months. so if you're reading the above info after that, make sure you check with me to make sure its still current.
