Default Correct Engine Dates.

My Second Flight, L-79, 67 Coupe has a Sept., (I 29 7), dated correct casting block. This of course makes it a 68 block. Putting cost aside I'm soliciting opinions on putting the correct block into the car. In this case I can obtain an E 05 7 correct, 3892657 casting block. Car born on June 6th. Present motor is fresh, under 5000mi.. Thanks in advance for your opinions. Al W.

Depends on the cost and what you want to do with it. To some this would make it worth 10-20% more. Of course, it would judge better.

Not to sure what it is you`re asking Al?3892657iscorrect for 67 300-350hp...327`s..
Do you want to know if it is worth spending the time and money to put the date coded block in your car?Well if you`re not planning on selling the car and it runs great at the present moment then I wouldn`t.Cheers...Patrick.

If it runs good keep it. If the non-matching numbers bothers you, trade it for one that has the original (not just numbers matching) engine.

Unless you want it judged and are shooting for a Top Flight, I'd leave it alone and enjoy it. For judging, in its current state, you'd lose 175 points for the casting date plus the 88 points for the pad; that's a 263-point deduction, and you can only lose 270 (out of 4500 for the whole car) and still make Top Flight.

The '67 block has a few advantages for you. It provides a correct casting number as well as a very close casting date. It is machined on the rear to accept the vent tube for a correct PVC system. That is, if all other PVC system components are incorporated. This in turn, allows the use of correct non-vented valve covers. Other things to consider are availibility and costs of needed items. If you have the correct heads, carburetor and intake I'd definitely consider the '67 block.
If you are striving for a higher point Top Flight type car, the engine change is a no brainer. Costs could be offset by selling your '68 engine. On the other hand, if you are happy with the car as is and drive the car regularly, enjoy it as is.
Anything we do to these cars is costly!
