Re: 1970 GMC 5.3/4l60e swap

The pcm is shipped off to Wait4meperformance to get tuned, my racing innovation stainless headers are bought but on back order, and I have a high pressure inline fuel pump on the way. Hopefully I can get it plumbed in this weekend when I am home (going to college and can come home a few times a month to work on it).

I am modifying my harness myself, and I am going to move the battery to the drivers side because that is where the harness wants it and I can use the existing intake tube, plan on just adding a cone filter.

I have got a lot of work done lately, I got the transmission cross member modified and got the engine wired and plumed. Brake booster in (thanks drew67) and power steering lines in. Headers in and I fired it up.

I got the headers from racing innovations. They are excellent quality but did not come with collectors so I have to find some 2 1/2 that are not reduced to tie in with my exhaust.

Got the exhaust tied in today and drove it about 125 miles with no problems. Great power and 18 mpg! I love it so far.
