Or change the bolt pattern on the heads and just run a pre-Magnum intake and swap over your old electronics and mounts.Elwenil said:It would be a mostly bolt in swap. You will have to obtain a Magnum carb manifold and 4BBL carb. Pretty much everything else will swap over from your old engine like the distributor, ignition, mounts, timing cover, accessory brackets, etc if you have a 318 in your truck now. You will need to run an electric fuel pump with this engine.
If the heads are crack checked and get a valve job before being redrilled it could be as much. Otherwise it's less. Those intakes are still expensive.Elwenil said:Eh, the machine work and head gasket set would probably cost more than the new intake.
They don't make an eccentric. They sell a cam nose extension for the eccentric to bolt onto it.Elwenil said:Ah, I was unaware that Hughes made a special eccentric for the Magnum engines.
I just did the thing so my heads have both bolt patterns. I can bolt any LA or Magnum intake I please on except the '64-5 273s.ToxicDoc said:Also, the Chinese-made "Crosswind" intake is a Performer RPM knockoff that has dual bolt patterns for the LA and Magnum heads. It is much cheaper than the Mopar intake (new). I doubt it's as good as the Edelbrock, but if you need cheap, it's a way to go.
