New build

[DangerousDerek]

So it begins (again).

Today i picked up the block and new parts to start the build. A forged internal 5.0





New balanced 86.3mm stroke crank



New I beam Chevy 6" rods



New custom 96mm forged pistons



New liner and rebore to 96mm




Now to put it together, hopefully in the right order.

[DangerousDerek]

Spring locks. The first one took ages then i got the nack and the others went in fairly easy.
Making sure the pistons point forward and the rods have the chamfers to the outside.



Done.

Waiting for a rather tasty cam and some other goodies to be delivered today.

[DangerousDerek]

Checking ring gaps. I am opening the top ring gap a few thou to safeguard for the nitrous.

Is a similar spec as mine ?

Out of interest what does a self build to that spec cost ?

Yes it wouldn't suprise me if yours was very similar Daz.

I think i got a fair deal overall from Roland at ACR.
Block work, crank, rods, pistons, bearings and seals £2800.

[DangerousDerek]

Pants. A set back i didnt need.

These are supposed to be brand new Crower solid lifters

Is that rust to Derek?

looks like it to me.
From V8 tuner. The order was rushed out to me.

[DangerousDerek]

Paul answered my email and said he would sort it out on Monday. By that i assume he means sending me a fresh set.

I got bigger problems however. The new crank is sticking at less than 70lb on the main ARPs and i see a crack in the thin metal behind the bottom of the replaced top hat liner. I am waiting on Roland to get back to me.

In the meantime i m trying to figure out how to set up my dial gauge to check the crank for any run out.
I think it will have to go back to ACR for a line bore maybe.

[DangerousDerek]

I had no issues with the studs at 80lb on the old crank.
There is something not right and it needs checking properly.

[DangerousDerek]

I am getting 6 thou run out on the centre journal.
Roland at ACR tells me this is within limits for a heat treated crank.

I am not sure i am comfortable with it.

[DangerousDerek]

After a chat with Roland i have refitted the crank following his procedure and tightening the side bolts in step with the mains. All seems fine now, turning over nice and smooth by hand.

[DangerousDerek]

4 in. 4 to go.

I threw the ring compressor in the bin, much easier by hand.

[DangerousDerek]

Couple of clearance issues sorted



All pistons are in and it all turns over nicely

macdeb said:

Nice deck height there, what thickness gaskets bloke? obviously you stripped and cleaned everything after the clearance issue.
only wanting to help bloke

Still needs a touch up.
I was careful but will be pulling these 2 back out to clean properly

[DangerousDerek]

Last pic this weekend.



Next Friday will be timing the cam in, fitting the heads and checking valve clearance then hopefully getting the engine back in the car

Spray some oil down the bores to stop any surface rust

Done boss. Even put a cover over it.
