Finally got some time to work on the engine block. The shop's been super busy and hectic plus expanded with more room now, but here are some work on the block.


Stock crank on the left, billet stroker crank on the right



After sleeve install, the block is then step decked. This helps concentrate the clamping force around the cylinders.



Boring the Darton Sleeves to 100mm.



Notching the bottom of the Darton Sleeve for oil squirter clearance



Oil squirter notched.



Machining 2 of the 4 main stud for 1/2" studs



More to come.....

 

are you gonna fill the block since its a race car?

 

no torque plate during the bore?

and 1/2" main studs?! that's insane

 

We will still run water in it. It's going to run on gasoline.

 

Torque plates are used during the honing process.

 

Thank you for the update Mark.

 

interesting. Never knew that. Any time i've sent a block to be bored they just ask if i want it bored with a torque plate and i always say yes. They never specified that it was a bore then hone with torque plate.

 

sub

 

you use a torque plate after bore, and during the hone.



looks dope, esp that crank. the oem crank is BEEFY. It weighs more than the block!

edit saw people already addressed @binder
The blades used for boring are different than the honing head.

The idea is to egg the hone job... the bores straighten out when under the torque of the head, and this egging is very small. You could do the torque plate on the block during boring but it would make little difference (until the honing stage). Shops will do the torque plate during the bore if you want, but they charge extra because its "more of a hassle" and not really worth the effort.

 

ya, after reading that checking the bore with and without the plate there was only about 1 thousandth of a difference then it makes sense to use it with the hone as 1 thousandth could easily be taken out with a hone. I guess since i never plan on doing any machining i just never asked. I just build the engines for the racers. I leave the machining to the professions.

 

Enough already... bicker in PMs or pollute your own threads. Fair warning to all has been given.

 

Update?




Also this version is cracking me up:

wow! they are retarded. Have they been living under a rock. The best is the all motor one lol

 

^+1 had to stop drinking my Monster as to not short out my computer at the all motor comment... This thread is full of EPIC WIN this thing is going to be a monster, i've very interested in what the results are going to be. keep up the awesome work guys, love to see this kind of work still happening.

 

i'll check you guys out soon!

 

Very nice work Mazworx. I am pretty interested in the Z with the same setup. Been considering modifying a kit to work much like that with the turbo right in the front of the engine...

 

I look forward to seeing the finished video, and seeing how you manage the heat. (heat being the opening of the season and the first set of races)

 

its a drag car, there isnt much need to manage heat. its got a 1/2 sized radiator

 

Bump for updates and cleaning the retard comments out.

 

We will start assembly tomorrow. Plan is to have it up on the engine dyno by the end of the month. More pics next week.
