My question is is there a 440-2 late model Indy intake that has the port dividers protruding under the carb like my 440-3? My 440-2 has the round casting for the fuel injection bungs and the 440-3 has the square casting, I think There both at the dyno shop now so I can't look at them. Last question on the 440-2, is there any performance differences between the early and late 440-2 intakes or is there such a thing? Last edited by Cab_Burge; 05/29/09 09:29 AM.

I took a picture of both intakes today, is my 440-2 the same as you have used in the past with the adapters? 5258955-MVC-026S.JPG (747 downloads) Mr.Cab Racing and winning with Mopars since 1964.

Oh well I have it and all I will be out is a set of gaskets and a spacer if it doesn't pick me up..... 67 Barracuda street/bracket car 11.27-119 68 Dart 502 BB 8.70s-152 414 cid SB Dragster 7.65-174

Some people have better results with the 440-3 when using a cloverleaf shaped carb spacer. 1993 Daytona, 5.50 at 130mph (1/8) 1.19 sixty ft (PG). Link to 572 B1 - Part 1

Was .05 faster yesterday but the air was slightly better then last week. I think I have fuel supply issues so have to look into that.... 67 Barracuda street/bracket car 11.27-119 68 Dart 502 BB 8.70s-152 414 cid SB Dragster 7.65-174
