Im not sure but that block looks like a tall deck to me.

 

maybe wrong crank??

 

I dont think the wrong crank would even come in to play, since the rods that he received are already showing being shorter than his stock ones....

 

thats what i thought. but the rod difference is what got me thinking.

isnt the tall deck dart just plain huge?

 

the rods are the issue, maybe even the pistons, who knows

 

dude whats up witht that block, dide you machine your own block out of aluminum opr something lol

 

its a dart block. thats what they look like

 

If the black one is a stock B20 rod and yours is significantly shorter it's pretty obvious you didn't get Manley LS/B20 rods, you probably got B16 rods but it seems like there's something funky going on as well. B16 rods would only put the piston a tenth down further in the hole then LS/B20 rods. Measure the deck height of your block, check out your pistons, and your crankshaft as well.

 

You have any better pictures of the block?

 

just some numbers out of the months honda tuning.
from the pic it looks like there is way more than 1mm diff.

b16a=137mm
b18a1,b20b4=137mm
b18c=138mm
b17=131.9mm
h22=143mm
h23=141.5mm
k20=139mm
k24=152mm

 

more math
137 millimeter = 5.3937008 inch

im goin to killmyself....... all i wanna do is BOOST

 

So you either have the wrong pistons, wrong crank, or a tall deck block. The rods are right!
Time to measure that deck height.

 

I love Dart Blocks.

 

That is a tall deck Dart block you are playing with. It is around 9/16" taller than the standard block, which is 211.5mm compared to your 226mm block. If you are using stock pistons and rods, you will get that result. I think Eagle makes a set of rods you can use with an ls crank to get your geometry correct.
My question to you is how did you get a tall deck Dart block and not know it?

 

Heres a picture for you to compare. Its a block form post earl made not to long ago.


Also, not sure whats up with the rod deal but if thats really a pr4 rod, then the manley is obviously the wrong one. When you measure rods, I think you measure from center bore to center bore.

 

i ordered a standard one and when it arrived i just dropped it off at the machine shop without checking anything, and when the assembly started to take place i came across that speed bump.


anyone wanna trade a tall for a ready to roll standard since im a moron.

what explains the rod length difference.

 

Assuming there *is* a rod difference between the stock B20 rods and those silver rods, someone really fuct up at that place. Whats odd is that there shouldn't be a 14mm difference between a B20 rod and any other b-series rod like that shows (almost an entire wrist pin bushing [19mm] short).

I guess you should make a lot of measurements, stroke/deck/rod/wrist pin height... BTW Earl's buildup was a tall block, yours looks the same. No idea about the rod diff.
