Thanks Buddy!   

[Duffil]

dude...LC all the way.

[Duffil]

He made a mistake,  he meant beach sand, not sandblasting sand.

yeah, sorry I get confused.  IIRC, the sandblasting stuff isn't rough enough to get a good finish on the cylinder walls.  Beach sand is correct.

kyle>>> <<<me

[Wermz84]

White, black, or tan beach sand? 

[Wermz84]

dude...LC all the way.

Ive been leaning that way.

[MiniSimp]

White, black, or tan beach sand? 

Black is probably too coarse. Go with tan.

[Wermz84]

Black is probably too coarse. Go with tan.

Sweet!  plenty of that in SC!

I think if I had EFI, or a carb that worked properly, this thing would rip my ass off.  It seems to pull hardest at like 1/4-1/2 throttle, like from a light...and then when you are driving at highway speed, it rocks my socks in 3/4/ and even 5th, around (what seems to be) 3000-4000 [no tach] Just roll on and there you go.

Of course, in my truck I hit highway speed in 3rd...

glad to hear this.  I tried calling LC today and talk about Cams and what my plans are, and probably to buy it.  But I forgot about the time difference.        tomorow. 

When I have the Head done I want the cam there to test it.

[THK Matt]

get pics mainnnnnne

[79coyotefrg]

don't go 2 big

[Wermz84]

Just got off the phone with LC.

Lets see.  ordered a cam, street performer springs, dual row timing chain kit and oil pump adapter.

same one as duffil.  1022024!   Now i have to figure out this whole clay thing to measure valve to piston clearance. 

[unclejpl4x4]

why
clay    how big of a cam did u get

[Wermz84]

It's not to big.  But John at LC said to make sure though.


Here are the specs.

20R/22R - EFI Pro Camshaft Split Duration
Smooth Idle (1200-5000 rpm range)
Throttle Body, Filter Charger, 1 1/2" Header

Intake Exhaust 
Valve Lash .008 .012 
Valve Lift 455 455 
Advertised Duration 285° 290° 
Duration @ .050" 238° 248° 
Lobe Center 102° 118° 


Intake Opens 8° BTDC 
Intake Closes 32° ABDC 
Exhaust Opens 45° BBDC 
Exhaust Closes 5° ATDC 


NOTE: Always check valve to piston clearance and valve to valve clearance with this camshaft! Failure to install this cam with matched valve train components can cause engine damage.

copycat.

[Duffil]

it's easy.  put modeling clay on top of piston.  place old, crushed HG on block, and bolt down the head.  rotate the engine over by hand, pull it apart and measure (with a caliper) the thickness of the clay where the valve pressed into it.

[Wermz84]

copycat.

Of course. youve already done the hard work.       Actually, it was between this and the street performer, he said this would have a better low end torque curve.

that doesn't sound to hard.  but I might be calling you anyway. 

where do i get said clay?

how much do I use, and just put it where the valves are going to be close?

[Duffil]

at the gettin place. (hobby shop, wally world, etc.)



I forgot to mention that: cut it in half along the indention, remove one side, and measure the remaining side with you calipers.  LC recommends at least .100".

[Wermz84]

I see thank you.   after compressing it, cut it open to reveal a cross section and then measure it.

[Duffil]

I seriously doubt you will have an issue...which engine do you have, tall deck or short deck?

[Wermz84]

84, so that is a tall block.  if i recall correctly.
 

[Duffil]

then y9ou shouldn't have any issues...I know I didn't and I have some not exaclty stock opparts in mine.

[Tallchevy]

Anything new?

[MiniSimp]

Anything new?

Nope, he wasted all his time at the Clam Chowder festival.

Got the LC parts in but have sicker than a dog.

OK, did some work today preping the block.  I'm going to have some boneheaded questions     I've also noticed a few things about the machine shop work that I'm not happy with.

I thought I'd start preping the rear of the block before I got in on the stand.

Here's the first thing that is kinda eh as far as detail of work goes.   Maybee I'm being to picky because this is my first build up,    He painted over old gasket material where the rear oil seal bolts up.  So I have to scrape that stuff off.  Do I need to make sure all of the paint is off?  (1st bone head question  )



Tapping out the Paint in the threads. 


Took me long enough to get this damn thing clean.  Lots of baked in grime in the nooks and crannys.   


New rear oil seal bolts from Toyota.  I could have sworn they would have a built in lock washer, I asked the parts guy "Are you sure those are it?" 



this is fun
