OK I need to order some Injectors what skin you guys think
Racetronix 48# high flow z or Bosch 50lb# green
I also need to order push rods I'm running the ls7 lifters what thickness should I go with 7.3 harden is the lengths

For the injectors id personally call Racetronix and see what they think, but I'm leaning towards the 50#.

Pushrods... The biggest you can fit. 11/32", or even a 5/16" but with a .105 wall.

Vettenuts went with some 3/8" double tapered or something and is very good with valve train. Maybe he'll chime in...

OK thanks.. I'll pm him. He helped me on figuring out how to check rod length pretty easy.. but thanks for chiming in

Lol Yea I wish I would get more done I'm at a stand still right now, I need to get the trans sent out for rebuild. Then on my next off day I will put the engine and trans on k-member bolt it up to car... next off day after that I'll hook up all the wire and make sure everything is plug in. Third and final day start up and off to the tuner: )

OK got my prs in today torqued them down, spun the motor, went to check the prs and got all this play?? What could this be from? I triple check for or length...

I have no motor in car I let the lifters sit in oil for a few hours prior to install, some Are tight and snug and maybe 2-3 is doing this?? What could cause this?

Burken01

iTrader: (88)

Did you follow the torque method?

Starting on Cylinder #1 @ TDC of compression stroke?

chevybayboy

iTrader: (6)

I sure didn't, didn't think I had to go by torque method if I had pr leght Martin sent it to me last year idk what I did with it... but I know cylinder 1 was def on compression stroke and that's one of the lifters that was loose

Burken01

Yes if you don't follow the method you can get a misread on the rocker bolts..

Because if you torque to 22 ft lbs and the lifter isn't on base lobe of cam then you end up compressing the spring a bit and get a false reading..

Then if you rotate the engine and check that same bolt, it could be a turn loose once the spring pressure is gone..

It's worth a shot to redo the bolts and see if it fixes it

I attached the method below

chevybayboy

OK I just redid it getting the same results, could it be because the lifters have no oil in them? I did this method then rotated the motor checked a few of them and they seem loose or could I have checked my pr length wrong

Burken01

iTrader: (88)

Hmm what length did you buy again?

It sounds like you measured wrong

chevybayboy

iTrader: (6)

7.3
I got the block decked and the heads milled, using ls7 lifter
I got 9.5 turns and added either. .75-.80 preload and came up with 7.300.. I thought they were sitting in oil but I guess the never made it to the oil, did a search on loose rockers I'm thinking because they have no oil in the lifters

Burken01

iTrader: (88)

9.5 turns x .050 = .475

.475 + 6.8 (PR checker) = 7.275

7.275 + .075 preload = 7.350 PR

So you have .025 preload right now using a 7.3 PR

chevybayboy

iTrader: (6)

I forgot to add in the Damn preload well gotta send these back and get the others sent out good news sending my trans out next week... should be running by the end of feb

Burken01

iTrader: (88)

But even at .025 preload there should be no movement..

I would try measuring again and be careful not to compress the lifter when doing it
