Eddies Vs 915 J's

Hi Frosty, I have seen a 340 out her in Australia make no more power when swapping from ported j heads to ported edelbrocks.

From what I have seen a j/915 head flows around 200 to 210cfm with a 2.02 valve and no porting. A friend had a set of std 2.02 valve edelbrocks flowed recently and they were 240cfm just with seats tidied up no porting at all.

The closed chamber head should give you a little bit more comp, assuming that your 915 heads are still around 68 to 70cc and haven't been decked a lot but then you will want more cam to take advantage of it all.

The 20kg saved over the front end of that little VC would help out as well.

Go the VC!
