Well it's about time I got something done...
I got my '79 to THE SHOP a few weeks ago
and dismantled the old bastard. He leaves behind a stash of parts that are going into this '78 and a bunch of other bits that are going to other trucks to help keep them on the road. RIP
Among the donations to the '78 are the Hedman Hedders (P/N 89210), a 4" Rancho lift, the American Racing 15" wheels with 35" BF Goodrich M/T KM tires and miscellaneous small parts.
The Hedders were a VERY pleasant surprise. I finally noticed the little stamped steel tag that's tack welded to the #1 tube. They're Hedman Hedders, so I contacted them to see if they could identify which Hedders they are. Spoke to Danny Lake
over there who proved to be really helpful. He had me send him some pictures of them and confirmed they're the 89210s. Turns out they're California legal; they carry an Executive Order from the Air Resources Board (E.O. D-167-27). Not only that, but he even sent me two of the E.O. labels so my smog guy doesn't give me crap. So, until the 400M dies, I'll use these bad boys. (Once that happens, it's all about the Cummins 6BT engine swap.)
The '79 also had a Weiand aluminum intake on it, but it wasn't equipped with EGR provisions, so I couldn't use it. (Still for sale in the Classifieds as of this writing.) So I swapped it for an Edelbrock 3771 aluminum intake with the EGR provision.
My new stickers:
The Hedmans and the Edelbrock have both seen some years, so they were pretty gnarly, so I took them to:
and had them blasted.
Angel took pretty good care of me. Here he is bead blasting the intake:
The Hedders got sand blasted and the Edelbrock got briefly sand blasted just to remove the surface crap and then bead blasted to really clean it up. I already bought some header primer and paint (both rated to 2000F) against the advice of some folks but my thinking is this: I'm not planning to keep the 400M or these Hedders for more than a year or two, so if the paint only lasts me a season that's ok. I will clear coat the intake 'cause I think it will look better longer that way.
The Hedders as they looked when they came out of the '79:
... and when I picked them up from the sand blaster:
The Edelbrock as it looked before blasting:
... and after blasting:
These guys did a good job for the money. I paid $50.00 and saved a hell of a lot of elbow grease & time. Hopefully I'll have time to at least install the Hedders this weekend so I can get the exhaust plumbed. I don't need cats (despite living in the People's Republik of Kalifornia) because I have a Non-Catalyst emission certification tag, so the muffler shop down the street said they can do true dual, header-back plumbing with twin Flowmasters for $250.00. Considering they want $100.00 just for the mufflers, I guess that's not too bad. I'll buy my own mufflers and show up to see how much they want just to run the tubing.
