Re: My rusty '68 "Custom" rising from the dead.

Im sure it could be balanced with the heavy pistons but would require several pieces of heavy mallory added to the crank in order to get it balanced which would probably about double the price of the balance job,the lighter pistons will likely require only holes to be drilled in the counterweights to balance and in my book lighter is always better.

Re: My rusty '68 "Custom" rising from the dead.

Found the shop to do my Jag IRS center section rebuild.
Not going to be cheap, around $1,500.00.
In addition to the 4.27 gears and Power-Loc rebuild he will also be supplying some parts to beef up the inner suspension points.
My 327/331 engine, M20, and 255/60-15 tires will certainly stress the suspension and diff more than the original Jag engine/wheels ever could have.

On the subject of my transmission.
I have a very good M20.
Wondering if I would be happier with an M21?
In either case I will be adding the GV overdrive.
As I recall reading the GV OD ratio is the same as an M20 shift so first OD is the same as second gear.
So no real point in using it until fourth gear OD.
But with an M21 it would provide actual gear splits.
M21 also has a taller first gear, not sure how much I would "Feel" the difference with the 4.27 rear?
No drag racing intended.
The funds for all of this are supposed show up "Any day now".

At these gas prices I want it 100+ octane, leaded, and my windshield washed!

Gear splits are already too close in an M20 for my taste, why go to an M21 and make them even closer? Again, JMHO

Re: My rusty '68 "Custom" rising from the dead.

Why closer gears?
To help keep the engine in it's RPM "Happy Place".

Last M22 I has was really in the wrong vehicle, a Jeep with V6.
Made it lousy for getting off the line unless in low-range, but was still fine once it was rolling.

I've got another build to do that is wanting a Muncie since ex-Camaro V8 WC T5's are suddenly hard to find or more expensive than an M22.
If an M22 would be better for the El Camino I would just put the M21 into the other build.

Re: My rusty '68 "Custom" rising from the dead.

Hot damn, Whopee, About time!
The "Big" check I have been waiting on to fund my over $500.00 expenses will come in next week!
Going to make a few shops happy as I "Redistribute" my fleeting wealth.
Going to make Me happy to finally get these items!
The danger is that there is a local swap-meet next week.
I just know that since I gave up on getting an aluminum block and decided to do a 'Glass front clip instead, somebody will have one for sale.

Re: My rusty '68 "Custom" rising from the dead.

So it seems I screwed up when I sold my double-pumper as surplus to my needs.
Going to have a fresh engine and cam to "Run-In" soonish.
So it seems I should have kept the DP to do that with since the Webers are not already tuned to this engine.
Tuning the webers while breaking in the cam and rings seems like a recipe for disaster.
Swap-meet on Sunday, guess I will be looking for another 4V carb to use temporarily.

Exclamation Re: My rusty '68 "Custom" rising from the dead.

Blasted check is still "In the mail"!
I have a confirmation it has been sent, just waiting on my &#@&#*! bank to post the deposit.
Going nuts waiting to drop about $4K into my build!
So I've been playing with on-line calculators.
If they are at all accurate it seems I'm building a "Ten second car", and I'm not even into drag racing!
With the Muncie, GV OD, 4.27 gears, 27" tires, I get a 3.33 final drive ratio.
That and an estimated 400 HP combined with a target weight of 2600 - 2800 Lb's leaves me with a supposed mid 10's 1/4 at around 125 MPH.
Top speed on the open road around 165 MPH, limited by the low gears but also more likely to be true than the claimed 197 MPH 3.54's calculate out at.
Really wish I could find the frontal area and CD of these cars.
But what I wish more than anything right now is that the check would clear!

Re: My rusty '68 "Custom" rising from the dead.

Paid at last!
Made several companies happy today when I placed my orders.
Now I get to wait several weeks on the parts to be made.

Re: My rusty '68 "Custom" rising from the dead.

Oboy, now I've done it!
JE Custom forged .040 over pistons for 10.75-1 compression.
Going for the medium betweem 10.5 and 11.
And yes, about $1K in expense.
I remember when this was going to be a budget build.

Re: My rusty '68 "Custom" rising from the dead.

I just can't seem to stop creating obstacles for myself.
Scored a decent but not perfect set of Corvette finned valve covers at the swap meet, $30.00!
I've wanted 'Vette covers from the start, trying to have a somewhat vintage vibe to this build.
Now the question becomes, where am I going to be able to add oil to the engine?
The CB Performance Weber intake has no fill hole, these valve covers have no fill, vent, or PVC holes.
May have to use these, https://www.summitracing.com/parts/edl-4203/overview/ but would be a lot happier without the Eddy logo.
Or maybe these? https://www.summitracing.com/parts/ott-6810
So much for my "Bargain" 'Vette covers!
And to add insult to injury, I will probably need expensive spacers to clear my rockers.
Sometimes getting it "My way" is more expensive than makes logical sense.

For sure, old gold anodized Morosos would have been =vintage too, and worked w/o mods! Still, fun stuff!

Re: My rusty '68 "Custom" rising from the dead.

Question regarding the Gear Vendor adapter... when I called them for an adapter so I could put my GV on a transmission that is more inline with what my car is built for.... they said "Sure. Send your gear vendor and adapter you have back to us and we will send you a new one... $2700.
Who are you using that can get you just the adapter?

I think i found them on this very forum!
www.bowlertransmissions.com

You do need to have the old adapters to exchange.

Some aspects of my build are a little "Tongue in cheek" satire of the stereotypes.
When I was younger EVERY owner of a hot* Chevy claimed their car had a 'Vette" engine in it.
So I just have to use 'Vette covers.
I do have a set of vintage Chrome Moroso's I may use during break-in.

*Usually meaning too much carb and a set of headers on a basically stock engine.
Bonus points for extended spring shackles to ruin what little handling ability any car left the factory with.

Re: My rusty '68 "Custom" rising from the dead.

Whew, got the heavy box of Jag diff parts shipped today.
Sent directly from the regional hub in an effort to limit how many times it goes from one truck to another.
I know the drivers despise moving 120 Lb. packages.
Hopefully this will go strait to Van Nuys.
