because a Magnum 318 is NOT an LA 318.

my truck came to me with a lowly 318. a performance intake, a new camshaft, some cheap generic headers, and a reprogram of the computer, and my 4,000 lb truck was running traction limited mid 14s (2.2 60' times, clicking through the traps at 95-97mph).

What did the 383 4bbl road runner do in the 1/4 mile when new?



for headers, look at spintech. they offer mid-length that drop right in with ZERO effort on the 2wd trucks (I think it would work on the 4x4, but I don't know where the torsion bars are on them)

Spin tech also offers long tube, but again, not sure on actual fitment on a 4x4
