Mopar "420" Iintake 4500 top for 440 CI SB

Just got this done last night now it has long trip to Australia.
Cross section starts at about 4.5SQ"(ave) and is 2.95SQ" at the flange should make real nice power 4000rpm to 7500~7800rpm.
This will be matched up with set of my CNC W9s on a street/strip car. It should be a fun ride.

I wish you had a program for that. Sure looks nice.We come up with a new water manfold to use on the new W-8.Would like to make some if others are interested.

Looks good Brett.. I just milled mine straight across

Why would you make it a cloverleaf? You think it makes more power this way? Looks good though, monster ports!

I have done it both ways I don't think it has much affect on power but I have not done back to back test to prove that.
This is for lower RPM street strip car so may help at lower RPM.
