Indy EZ, talks the talk, walks the walk.

Well, if I was going to run a standard offset rocker in a aluminum head with a stock intake port opening, I'm going RPM or Stealth.

If I'm using a standard offset rocker with a Max Wedge intake window height, its the Indy EZ. Never fully tested an Indy head myself, until yeaterday, when I pulled a plain 'ol standard intake 440-H1-SEZ-1 from the shelf and did some porting. The EZ that I tested has the stock size intake opening so you can bolt up a factory cast iron manifold or an Edelbrock RPM or sumpthin' like that.

Here are the out of the box flows.

.100".........69 cfm
.200"........131 cfm
.300"........190 cfm
.400"........239 cfm
.500"........283 cfm
.600"........307 cfm
.700"........313 cfm

I opened the intake window to Max Wedge height but kept the stock width. This will make it so I cannot use a Max Wedge opening manifold because the ports on that style intake are too wide. But Edelbrock has the answer in the Super Victor 440 part #2891, because you can port it to any window size from stock to Max Wedge. After the porting and several flowtests, this is what we came up with.

The first column is the configuration I would probably choose to run and the second was only to see if I could push it to the 370 cfm range.

.100".........81.........74
.200"........158.......151
.300"........220.......214
.400"........265.......265
.450"........288.......288
.500"........308.......308
.550"........331.......331
.600"........345.......347
.650"........354.......358
.700"........358.......362
.750"........362.......368
.800"........368.......372

Standard offset rockers and throught the shaft oiling, WOW! I'm becoming an Indy fan.

Now if I only had a set of 440-1 to test.

Well........maybe I don't even need 'em now.
