Default Re: 350/360/330 SBC with Edelbrock heads

I'm an Old Guy, so help me out....

I looked up the e-Brock specs on these NHRA replacement heads.

I found that 3 of the part numbers had Intake Runner Volumes of 185cc..

I found that 1 of the part numbers had an Intake Runner Volume of 170cc.

I noticed that in the tech specs that the Intake Runner Volume of all of the Factory Cast Iron Heads have an Intake Runner Volume of 165cc..

The e-Brock heads I believe are SS only because they would have to be filled and ported out to size, which is legal in SS but not in Stock.

What did I miss??????

Thanx.

The 70 and 71 use the same grill. The 72 has larger openings and is silver colored rather than black. The 71 has high back seats while the 70 does not, but no longer a factor. I've run my car as both years, currently as 70 with 360 hp. I think the 71 flat top motor at 315 may be slightly better. I've always run a 4 speed at altitude tracks but am certainly not as fast as Andrew.

There has been some discussions with Dart as to making a pattern for 165 CC intake runners. Use the same part# for NHRA approval process. Then you could get to 161 CC applications as well.
There are guys running aftermart heads with no modifications to runner volumes...
Bigger intake runners don't always mean the you will be a faster.
