460 starter issue

[ArdWrknTrk]

I've had the Lakewood bell housing that fits.

It's a good enough piece, but it's not stock,
 or cheap....

update. one of the heads is cracked. on the search for plan b if not c. my source can get me the matching casting code head as a reman but it is not cheap. gave info to customer for decision. now waiting. I tried to explain that the known is a set price where the search is not. it could cost more to find, collect then have machine shop repeat. I am getting an education in 460s. wow. they sure made a lot of variations.

I THINK I have a freshly rebuilt CNG D3VE-A2A without provision for thermactor at the barn in Wilton.
It would have flash rust but otherwise be freshly rebuilt with the heat tag on the end.
I bought a few heads from eBay that were said to be from a defunct machine shop in Texas that refurbed pumps for the oil industry, so corners were not cut...
(I KNOW I had it, I just don't know if it's been tossed out)

I'm not sure if or when you need it, but I really should go by there and get a load of stuff.
Having my axle blown up is putting a damper on a lot of things... 😕

[ArdWrknTrk]

Wait!
E7 fuelie heads on that truck?

I don't have anything like that, and the 450 engine is gone!

How do they have a carb on it?  
E7 lower plenum with a Price Motorsports adapter, or carb intake with plates at each head?

What are they using for exhaust?

The E7 ports are moved so far you can't really use a carb intake or exhaust with them.

[Gary Lewis]

Right, the EFI heads take a different intake and exhaust than the carb heads.  And there are two versions of the EFI heads with the F3's being slightly better.

[ArdWrknTrk]

But the ports match between E7 & F3 heads.

this is where I am getting the education. the master book of compatibility we were using at the machine shop showed block, head, crank assembly combinations. that were documented from the factory. oddly the c,d,e,f casting codes did not follow what I have always "known". the block casting came up as possible from 71-79 as did the crank, yet the heads came up as 87 mfi. this engine has the cast iron 4 bbl. that weighs 80 lbs. and a new Holley. at first glance I knew something was odd with gray valve covers on a blue engine, but I did not think I was going this far off track. if the heads were put on as replacements, then it was a long time ago. they certainly looked original but hey "87". even "97" is almost thirty years ago.

[ArdWrknTrk]

E7 heads won't fit any 4V intake I've ever seen.
You need either the lower plenum with a $100 plate and plugs.
Or aluminum plates to adapt a carb intake with an intake gasket each side of the plates.
Price was an innovator in CNC parts back then.

EFI heads have different chambers and valve angles.
You can get away with putting them on a carb motor but you can't have a hairy cam, or true flattops without cutting proper valve reliefs.

[Gary Lewis]

I do not recommend running a carb on an EFI lower plenum as there's not much torque below 1500 RPM.  Apparently they weren't designed for fuel in the air stream and it drops out of suspension, causing a lean condition.

So if you are running EFI heads then the adapters and a carb intake would be the way to go.

[Gary Lewis]

Yes, adapt the carb intake to the heads.  Don't adapt a carb to the EFI intake.

The very-worn 460 in Big Blue sporting Edelbrock's intake, carb, and cam pulled like a tractor from idle.  The new engine from Scotty with his cam and carb adapter on an EFI intake didn't start pulling until 1500, and didn't have any more top end than the worn out engine.  But when I went to EFI and got the fuel out of the intake the engine woke up.

[ArdWrknTrk]

You were waterboarding Scotties engine.  💡

[ArdWrknTrk]

Mat,
If you're already gonna have to replace one head and have an iron 4V intake, do both, and get the D3. A2A's instead.
Junkyard heads are not expensive.... still.
Magnaflux them and clean up the valves.

You will be saving a ton of time and frustration trying to get the reversion worked out to where that thing will run right with EFI heads.

I'm not sure where you are Matt, because the map has you in Nashville.

But this salvage near my brother's farm in Siler City is a good one. 👍

[mat in tn]

actually, I left Nashville a year and a half ago. I am now in Lexington NC. a small rural city south of Winston Salem. I had to get out of Nashville as I watched it lose its soul over the forty plus years. I'm not going to go on a rant about "other walks of life". to each his own. however, I'm not afraid to claim Christianity, patriotism, and constitutionalist on a resume'. I'm an American dammit! but first and foremost I am man! as created!
I'm not sure where siler city is. I may have been close and didn't know at some time. I'm always going somewhere. just got home from the coast an hour ago

[85lebaront2]

Gee, I wonder who explained that to you?

[ArdWrknTrk]

Maybe Dave G can explain it to you.
He drives Propane all over the center of the state.  ????

Or you could click the link. I'm pretty sure they have a 'directions' tab.

just getting back on what took way too long. finally got all parts in house and got the 460 completed last month. waiting on parts really gets old. all installed with an auto separator plate and new clutch. primed the oil pump for an extended time. set dist. and when we started it, it fired immediately as if it had been running and dialed in already. timing was as perfectly on 0 as I have ever seen. a quick adjustment and a good break in and it runs awesome. I'm sure it will return for more as time goes by since there are cosmetics that he wanted before the engine costs got away from him.

[Gary Lewis]

Glad it worked out so well!
