Full Filling a 4G63 Block with Cement 1,000HP block, Hard Blok Filler Tips

[@joseantoniodaly4875]

Is it a problem if I use this filler AFTER block bored?

[@nexxracing]

So for this filler they manufacturer states it can be done after block is bored. I would definitely recommend checking piston to wall clearance after you fill it to make sure nothing has changed!

Can you fill a block after it has been machined (bore and honed,, mains aligned)?? If you fill a block 100 percent can you just flow water through the head...for light street driving.

[@nexxracing]

HardBlok says you can fill a motor even after it’s been machined. I just prefer to have it done before it’s machined. Now that’s hardblok , the moroso engine filler you have to do it before the block is machined cause it changes the blocks shape a little. Now I do plan on running water through the head , but my motor is for drag use. I wouldn’t recommend a full fill for street use unless ur running methanol which lets the motor run at cooler temps. Just my opinion tho!

You can't drive a fully closed deck on the street, maybe for a few minutes

[@TTGTO288]

No, fill it before.

A creeper stool could have made the task much simpler.

How do you unfill it?

[@SpeedGasmEvo9]

How long can you run a full fill block for?

[@nexxracing]

Depends on some factors but id say its not something you’d want to run for more then 30min at a time. In terms of longevity of the block just depends how hard you run the block and the upkeep .

[@TTGTO288]

Guys like this make me laugh. Probably takes the block to the machine shop and says "deck it" with no measurement to deck it to. Guys like this make my engine builds look great, like top fuel dragster engines.

[@nexxracing]

These blocks still have to get bored, honed , line honed, decked , make sure the piston to wall clearance is to spec for the HP im going to run. Not sure where you get that I’m just going to deck it. I’m not one of “those guys”. Appreciate the negativity though!

What is the service life of your blocks after this treatment?🇦🇺🦘👍

[@nexxracing]

I mean it doesn’t change the service life, you obviously can’t run coolant through the block so the block can only be used for drag racing. Just depends on how hard you’re running the motor.
