Default Canton Valve Covers and OTVC Wires

How much taller are the Canton valve covers VS stock?
My OTVCs are cut to fit the stock covers, I have a feeling that switching
to Canton VCs is going to mean buying new wires.

Engine was out for a 355 swap, VCs are a last-minute thought.

Is your alternator in the stock location? If so, you will most likely have to
do some modification to the Canton's and the alternator.

I didn't measure the difference but I'd bet they're almost twice as tall. We just ended up running the wires under the headers and using the motor mounts to keep them off the headers. I didn't have to make any mods to the canton's or alternator other than grinding a little off the inside front of the passenger cover to clear the rocker but I think that was because I have the big Comp Pro Mags.

Thanks Kyle, I run Promags as well.

I think I'll stick to stock covers for now. We can think about taller ones later on.
It was more of an asthetic mod than anything else.

Turns out my 383 needs taller covers to accomodate the taller pushrods and longer valves on these Darts.

Looking at my options now ... motor is ready otherwise.



Note: I ended up scrapping the 355 mentioned above and building a 383 with LE-ported Dart Pro heads instead.

some guy brought in these valve covers in for his LT1 that were to high and hitting the alternator. i put the top that did and welded a peice of angle iron in its place so it would clear the alternator. the guy said it worked great

James what heads are you using? I have some modified tall LT1/SBC covers if you want them.

Running ported Darts heads.
Standard center bolt should fit, my alt is in the stock location.
Running Promags.

Lemme know what you have and how much you want for them.
I just want to get the motor in the car so I can start using it LOL

Thanks anyway man. I think I'll just BFH myself some Cantons or look into the Proforms.

Adaptors suck. I have run them before. The only way to make them stop leaking was to use The Right Stuff by Permatex. The Dart heads don't have provisions for perimeter bolt covers?

That sucks, you would think Dart would have put them on there like some of the other head companies. It looks like the bosses are there though.

Yeah, I suppose I could have machined them in while the heads were off if I'd known I was going to run into issues.
Probably not a good idea to attempt that with them on the motor.

But I agree, they should come that way from the factory, I'll include that in my feedback to Dart.
