Your done after you ck the crank for straitness. You might already know this, but its crucial with that balancer that all the bob weights are exactly the same distance away from the radius of the rod throws. I use a drill bit for this.

If anyone remembers the Grant quick disconnect saga, I recieved an e-mail from Summit yesterday (1 year to the date of original order) it should ship in 8 weeks. :D:D:D

Re: H-I-J '76 Nova re-fit.
 

HP, I'll make some video for you to see when I check it today.

Re: H-I-J '76 Nova re-fit.
 

L2L said .003-.0035, I didn't however mention the block was filled.

Re: H-I-J '76 Nova re-fit.
 

Here are a couple videos I did today of the cranks being checked. I re-setup and checked these again just so everyone could see since it was mentioned. The videos are a little hard to make out but the first video is the old crank with maybe a tick over .001 runout. The second video is the new crank with under .0005

Re: H-I-J '76 Nova re-fit.
 

Lot's more block work to do, started boring today but my time may get a little complicated for a few days, I'll go as much as I can.

Re: H-I-J '76 Nova re-fit.
 

Did you ck the number 4 main, then the seal surface, then finally # 2 then the snout?

Re: H-I-J '76 Nova re-fit.
 

No, I only checked the center.

Re: H-I-J '76 Nova re-fit.
 

I finished a bracket for the rear today (not sure if it will work or not), did a little grinding on the collar for the trans. and finished some real "boring" block work. Had so much fun we may do it again tomorrow. Home watching drag racing YIPPEE!

Re: H-I-J '76 Nova re-fit.
 

So you are mounting the race pak sensor for the trans through the fill hole?

Re: H-I-J '76 Nova re-fit.
 

No, I'm going to drill and tap the case under the fill plug to line up with the counter shaft.

Re: H-I-J '76 Nova re-fit.
 

Tapped holes for all the pipe plugs today and did some more grinding and chamfering on the block.

Re: H-I-J '76 Nova re-fit.
 

Not much done today, only the lifter bores grooved.

Re: H-I-J '76 Nova re-fit.
 

Why????????????????????????????

Re: H-I-J '76 Nova re-fit.
 

LOL ahhhhhhhh

I can only say we go to great lengths to control oil leaks in the engine, and 16 lifter bores is definitely one of the places were looking to control.

Re: H-I-J '76 Nova re-fit.
 

Because I don't think the cam will live with 400+lb of spring pressure and no help.

Re: H-I-J '76 Nova re-fit.
 

I’m glad I was not the first one to say WHY ?

Geez.

I built a low buck 350 for my buddy when he first started racing.

Cast HyperE pistons, cast crank, stock rods, flat tappet cam with .012” EDM’d lifters

Cam had .500+ lift I’m sure and 400lbs open pressure or dang near it.

It lived for years and went 10’s in a 2800-2900 lb Camaro running brackets and S/ST and the engine got sold running minus top end ....

Re: H-I-J '76 Nova re-fit.
 

This makes no sense to me. You did the same thing only with the EDM lifter.

Re: H-I-J '76 Nova re-fit.
 

What size are those grooves? Lifters have edm holes? Didn't you have an oiling problem already?

Re: H-I-J '76 Nova re-fit.
 

Cutting grooves in the lifter bores can’t be undone.

Using the EDM hole lifters is an option and can be changed.

Some Stocker racers use Schubecks or Trend lifters and run tons of spring pressure.

The engine I built was low buck and the lifters were cheap.

It had good oil pressure and never hurt the bottom end

You could have used the edm lifters with no grooves and if that worked you were good. If it didn’t you could step up to better lifters. No grooves to complicate the build.

Re: H-I-J '76 Nova re-fit.
 

I have 4 sets of lifters, I tried EDM lifters and didn't like them. My preference is the groved block with non EDMs. I know not everything I'm doing or have done will be popular, and I'm ok with that. In my opinion there will never be advancement if we all do the same thing. I could have called any engine builder and had one built, I could have just paid 50k for a sorted out car, not my style. I appreciate all the help and advice, but sometimes I just gotta be me.

Re: H-I-J '76 Nova re-fit.
 

Grooves are .006, no edm holes in the lifter. This engine ran fine for years with grooved lifter bores (as have others), current oiling issues are not related to this.

Re: H-I-J '76 Nova re-fit.
 

The groves look wider than the thickness of two hairs.

Re: H-I-J '76 Nova re-fit.
 

Hey.......when I get get something in my head I won't be stopped either
(just ask Dissident) carry on.......just be sure to show us the results.

Re: H-I-J '76 Nova re-fit.
 

I fully realize that I have no skin nor treasure in the project that Todd and Autumn have shared.;)

However, when it comes to some technical items and issues, I think it is necessary to make those issues obvious before one goes down a problematic pathway that may be paved with lots of "he said, they said, everybody knows..." kinds of guidelines.

For a SBC (2.45" mains, 2.1" rods) with normal racing clearances, it is worthwhile to note the resultant internal oil leakage sources.

These data are as listed from items indicated:
Lifters (16) = total diameter of an orifice = 0.2323"
Cam brgs (5) = total diameter of an orifice = 0.2369"
Rod brgs (8) = total diameter of an orifice = 0.2899"
Main brgs (5) = total diameter of an orifice = 0.2476"
Will leave it to others to evaluate what those orifices flow in gpm at various pressures. It is quite eye opening!:D

Anyway you might look at it, that is a lot of leakage when you consider whatever psi one might want to evaluate. A builder is logically charged with the responsibility of how much and how to control the leakage paths. Sorry for the brief hijack of this otherwise very interesting thread.

Tie that hair back!
She may not be running the machine; it's just a great habit to be in.

Re: H-I-J '76 Nova re-fit.
 

She doesn't have safety glasses on either. She also rode in the back of a pick-up last week. Can't tell these crazy kids anything these days!

Re: H-I-J '76 Nova re-fit.
 

Stocker Stuff! Autumn got the rods numbered, bearings put in and ready to check clearance. Measured the deck, got the crank out and back in the balancer. Autumn was busy today so I went at it alone and started squaring up the deck (made me video it so she could watch).

Omg, next you will tell us she drank water from the garden hose ! !

Re: H-I-J '76 Nova re-fit.
 

LMAO, that's funny.

Re: H-I-J '76 Nova re-fit.
 

Actually not funny. These habits, or lack of, put me in the ER with a metal chip in my eye.

Re: H-I-J '76 Nova re-fit.
 

Seriously you guys need to f-ing lighten up! Someone without their hair up, safety glasses, knee pads and a helmet screwing deck plugs in a block and it's like we're doing donuts in a daycare with a dump truck. I think I need to put myself in time out for a while... this place is a nice reminder why I don't hang out with up tight geriatrics on the daily. I was warned about this early on in this thread by people here in the builds section, I think I need to put this thread up on blocks for a while!

Re: H-I-J '76 Nova re-fit.
 

Todd, don't do that.
I, for one (and obviously speak for alot of others due to this comments on this thread), have thoroughly enjoyed your build and would hate to not see it through completion. Don't let a few comments bother ya, sir. Just ignore them and move on.

Re: H-I-J '76 Nova re-fit.
 

Love your build progress but whatever you do don’t run with scissors LOL

Re: H-I-J '76 Nova re-fit.
 

I too would hate to see this build documentary not followed as closely as you have provided. Its an awesome build and everyone can enjoy the time your spending with your daughter..


BUT I 100 TOTALLY AGREE with your sentiments... people need to shut the hell up about every little thing the man is doing.. or in this case not doing.. if you don't want to groove lifter bores, or you just have to tie your hair up and wear goggles to tie your shoes THATS FINE.. but this man doesn't need to. It's his build, his engine, his car, his life, his daughter.. you can show genuine concern for something and in a pleasant manner address said concern.. but WAY too often in this thread people have downright told Todd he is doing something wrong or what he should be doing without even trying to understand his reasoning for the way he is already doing it.. build your own damn car if you want it done a certain way. Constructive suggestions I'm sure Todd is grateful for and welcomes as he is making final decisions. but re-think what your typing if you want Todd to continue putting his build out there for all of us to enjoy..........

Re: H-I-J '76 Nova re-fit.
 

I'm out.

Re: H-I-J '76 Nova re-fit.
 

I've never been anything but respectful on this thread or any other on the web, for that matter.
There are many ways to skin a cat (build a motor), that's for sure.
Todd, you've been more than respectful in all of your posts, to everyone.
I've enjoyed this thread also. It's unique on the web. Keep it up!
I've worked in various industries where a simple movement can have disastrous results. My comment was with respect for Autumn's safety. Safety is about doing everything correctly all of the time, so the unexpected can't happen.
I didn't mean to step on your toes, Todd!
