Should i keep 429 cast iron 4v intake or get aluminum intake

[crazyhorse]

If this is in the wrong place or not allowed, please delete.

I have a 72 Ranger XLT short bed with a 69 Mercury 429 cubic inch motor & c6 automatic transmission, it is leaking a little antifreeze some where around the intake manifold . When I drive it 20 miles or so little puddles of antifreeze is on the intake.
SOOO I think I am going to need new intake gaskets.
The motor is stock with stock cast iron 4 barrel intake & Edelbrock 650 carb.
I have electric fan and MSD box, distributer , & etc.

My question is it worth the money to replace the stock cast iron intake with a aluminum 4 barrel intake since I will have to remove the cast iron intake to replace the intake gaskets anyway , & if so what kind of aluminum intake and will I have room between Carburetor , breather to close the hood ?
Would I have to change any linkage or intake hook ups ?

It runs good like it is but you know we are always looking to improve.
I plan on leaving the motor stock like it is.
Thanks for all the comments/tips/information in advance.

It's a personal preference, On my street truck I've got a Edelbrock performer, on my mud racer I used a Weiand Stealth.
On my bone stock snowplow truck I kept the cast iron.
Aluminum is lighter and looks better if you keep it clean.

I think that once you finish lifting that cast iron boat anchor out, you will definitely want to buy an aluminum intake

If you’re going to stay stock otherwise I would probably keep the stock one, though Sparky speaks truth.

If you do go AL, look for a dual plane with an RPM range that starts around idle. I would not expect hood clearance issues with that type of intake.

Honestly, if I was gonna spend money on your combo - EFI.

A Weiand Stealth would be my choice. Great intakes with a wide power band that runs from idle to 6800. Good deal too - $250 from Summit right now.
