Did the 1979 Lil Red Express come with an air pump?
This will not help the question on 1979 LRT air pump. But my story on what cam is in mine.
I have the EH1 from my 1978 LRT on a stand buried in the garage. The engine was pulled and regasketed around 1989 due to leaking coolant at right headgasket. Has steel dual chain cam sprockets, Windage Tray. The cam was sent to Delta Cams in Tacoma to have it checked and reground to the 340 HP spec's and they said it already spec'ed out the same as a 1968 340 Auto. He said he could regrind it to give it some more lift but I said no. He did regrind a E58 cam to Heim specs for me but I did not use it in the EH1.
Has a spun rod bearing.
If I wanted to, I could pull the cam, set it in some v blocks and measure the loab lift. Just too much going on so not happening.
The engine in the LRT right now is a 1977 E58 from a Dippy Cop Car. Had a nylon timing gear but does have a windage tray, 6 blade water pump. A set of highly ported closed chamber 1967 273 heads with 1.88 intake and 1.5 ex. Put a HEMI Grind cam in it. Really does not have much lope, some but not a lot. But will set off all car alarms in the neighborhood. A999 with low 1st gear, 3.55:1 gears and 265/75 15s and pulls like a freight train. Block has a crack in the rear China Wall and leaks oil bad.
