Texas240 was 16v but now LM7 5.3L

A few good arrived in the mail today.. Just need to get specs from the bores and crank journals so I can order rings, bearings, and pistons.

Give RSI a call, that new blue slickem might have a different torque than the older white bottled stuff. My head studs do.

Are you doing pistons, or just rods?

Goodluck with the innovate.....I just ripped mine out!

I don't have a clue, I wasn't expecting it to come with arp bolts. I will be doing new pistons but just new stock ones
 
THIS IS PICTURE HEAVY!!!!

Work hours have been dropped from around 65 to 40 hours a week so my time is quite free now. Did some heavy work on the head today. All I need to do is order new valve guides since 2 are cracked and I thought I'll just do all of them since im not sure when the last time this head was serviced. Get it checked for trueness and then skimmed to clean it up, stick in the parts washer and put it back together.

Found out that there are 5 exhaust valves that are severely burnt and one intake that looks completely different on the face of the valve such as 7 of them are smooth and the other one has a texture like an orange.

Now for some pictures.

You can see the differences in the valves and Im sure there is story behind it

Main body of the head was in very good condition and didnt need a whole lot of hand contact, just some engine degreaser and a garden hose

Cam carrier was nasty but got it pretty clean and ill throw this in the parts cleaner next week.
 
Oof, looks like someone tried to seal the lower and upper head together with silicone sealer last time? Hopefully didn't seal the oil passages too!

Kenny found a bunch of cracked valve guides on my new head too. I figured it broke a timing belt and hammered some valves, and someone just did a half assed repair on it by tossing new valves in.

I hope thats not the case on mine, but It wouldnt surprise me that one of the reasons the car was junked was partially to the burnt valves.

Where does one find the volvo pink sealer between the bottom and middle section of the head?
 

Ohhh, youre funny :oogle:

Got all the good measurements from the block:

Bores:
3.7812
3.7813
3.7808
3.7811

Im not really sure what to do at the moment for pistons? Bore out that one small one or some how find stock volvo pistons that fit the bores like Volvo did at the factory??

Mains:
2.4803 ( stock specs {2.4798-2.4803} ) So those are within tolerance

Connecting Rod Journals:
1.929 ( Stock Specs {1.9285-1.9293} ) All good there.

Still stuck on pistons, so any buddy with some real knowledge... Cameron, Nathan, John Mc.. Hmm Hmmm would be sweet:roll:

hows the crosshatching look? and i hope you checked the bore measurement at the bottom, then at the top. if the bore measurement at the top is bigger than the one at the bottom you'll be in some trouble (tapered cylinders). My b230 block had 115k on it. It had no lip at top, and had plenty of crosshatching. I just honed it, threw in some turbo pistons, and new rings and voila.

No lip what so ever and bore 4 looked great with good amount of crosshatching. What about the difference in the piston measurement and finding the right piston letters?
 
Looks like somebody who thought they knew what they were doin was the last one to work on that head........get it cleaned up, put some new shiny parts in, and boost it.

Dont worry about a tight squish on a 16v, theres not much there to worry about like on an 8v.
 
Now wait, you went forged rods, and are not going to go forged pistons? Whats your plan for this motor? EMS? power levels and turbo type? Dont kid yourself, I have made like 4 jumps forward since I started.
