Sleeving 1gr help

A lot of this info is like reading Japanese. I know little of what you guys are relating.
I was told by Darton they’d sleeve the block. Reason is for the stage 3 sc.
if it’s not worth the cost and hassle, might as well just build the motor with better internals and keep it n/a?
Picked up a motor from @mightytacoman drop in ready. I’ll use that for now till I figure what I should do. I am planning to sc it. Stage 2?

 

As far as tuning? I’m just using what’s in the urd box

 

Don't sleeve the block that has damaged main journals. Worthless. They would have to be machine true, then bearings would have to be sourced. That will likely be the harder part.

However, if oversized main journal bearings can be found, then it can work. I find this a much lower percentage a possibility.

 

I have a spare block as well

 

Perfect

 

not rocket science

Sleeving REMOVES metal from an already weak block

blocks move around even when stock

they Move even more when overbored or sleeved..................resulting in components

MISaligning & tolerances distorting

U can handle that

 

The sleeves job completely removes the oem cylinders. Which are of the open deck design. The Darton M.I.D. (Modular Intergrated Deck) then fit tightly in the block acting like a closed deck block. Adding rigidity.

 

I understand what U say

not in ANY attempting to undercut what U do

any reputable engine will tell U a fact in reality

a brand new virgin block moves around !!

a block bored or sleeved moves around

most engine builders realizing thats a fact in reality

rather deal with a seasoned block...................brand new out the crate AINT SEASONED

its a minor thought concept removing metal weakens the block

many seldom run engines MAXED out for a few seconds at a time

endurance raced for years

getting ANY engine to hold together for 6......8 ........12 & 24 hours this is a MAJOR Consideration

E V E RY component reaches heat soak street engine NEVER gets to

that a drag engine NEVER gets to..................EVER
