You can also get all the parts and pieces from Chicago Corvette,and usually cost less than buying from Holley.

Also,being that your manifold has been modified,I would remove the center portion of whatever gasket you use to match the intake.




There are walls removed out of the manifold, are they? I just wondered a second about that but did not realize that it has been modified in all three intakes - I was just focused onto the carbs.

Why someone would do that? What's the result, how does it change behaviour of the engine?

Do you recommend me to replace it? May be against aluminum like that ?


After all these years having a 440 I realized that this means having an attitude... and a budget.

Call Promax carbs. They sell the base and gaskets.

Tried it by mail - I ALWAYS try the Moparts sponsors first. But they should read their mail.

Calling is experienced to be *hard* for non native english speakers ... last time someone explained me a hell of a lot of things over minutes and minutes that I couldn't really follow .

Thanks to you all for your efforts! I better don't imagine how my project would go without moparts...

And on the gasket of course...




First, get the proper choke thermostat if the one in the picture above is what you have, it's incorrect. Maybe I'm missing something, but how's the motor spec'd out? Cam? heads? power brakes hooked up? Possible vacuum leaks other than the baseplates? Typically on 440's with pretty much stock cams and no vacuum leaks, they should purr like a kitten all day long, yet put you in the back of your seat when you open them wide open.

Yeah, well... there are a number of parts that are not correct at that car (call it my shameful old bucket). When I bought it in 2001 (for quite a reasonable price)I knew that it's a clone. But I wanted it . Then I started in 2007 to "repair only the transmission".

Now after all the time I found incorrect parts everywhere - and decided to leave alone whatever works and looks well . I was very satisfied with the engine, it pulled a hell of hard and cruised well - only idle was not reliable .

I'm very surprised (one time more) that the manifold was modified. After googling a while I found out that some people did/do that with that particular manifold ("notch out the dual plane divider" - while removing it entirely is not exactly that) to rise top end performance. I think I leave the manifold since I really cannot say the engine is weak at low end.

Choke just worked - however it opened the flap when hot and that should be alright.

I also checked the outboarders in the meantime and found that the rear was tight while the front had a small leak too, but not that much like the center, which indeed had a wide leak. It's perfectly visible when checking the old gaskets if they were seated between surfaces or not.

So I'll give it a try to just sand down the baseplates of center and front and apply a renew set to the center. May be I'll cut a bit fatter gaskets for the baseplates myself - can't take a 1/4" spacer since it's very, very tight under the hood. I think sealant is not the best choice since it's hardly gas-resistant.

And I'll replace all the rubber hoses against fresh. Have manual brakes, so no leak possible there.

I assume the engine may be more stock than not - not too seriously modified. There are still hydraulic lifters in, that's what I could see with valve cover off. I really don't want to take it apart when it runs that good.

I'll see how the first try works ...

You can save $100 by purchasing it as an Edelbrock instead of Mopar Performance. Same exact manifold, just bypassing one of the middlemen. http://www.summitracing.com/parts/EDL-2475/


In theory, there is no difference between theory and practice. In practice, there is.
