Re: IML: A Edelbrock CH4B Intake on a 413 ?

When you change the intake manifold on your 1962 413 you will find the newer 
carbs have a different throw in order to operate.  After you read this message 
go to the car and while under the hood area move the throttle linkage.  The 
manner the carb arm is moved at the carb is a complete opposite of the newer 
cards.  The second thing is the Air Cleaner Housing will not seal to the new 
carb since the new carb has a larger neck opening.  The last part of this mod is 
the newer carbs have a different carb to manifold bolt pattern so you can not 
try out the new stuff until you get all the parts.  If you fill that you must 
change the intake manifold the best for the buck is the cast iron unit 
installed on any 68 and newer 440.

At the allpar.com site is a note on how to figure the correct carb for the 
rpm's that you will be running at.  With a 750 cfm'd carb you will be spending 
more than normal time at the gas pumps.  And with the 750 cfm'd carb you will 
find that due to the weight of your 1962 2 door Custom that you will be 
watching license plates 'cause the 413 will be bogging on the low end due to over 
carbing.

What kind of a exhaust system do you have ???
