350/360/330 SBC with E-brock heads - CRICKETS

[Bob Mulry]

I asked this question on another thread a few days back and nobody responded.....So I will try again as a new thread....
************************************************** ***************************

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.

I think you are answering your own question, if I am understanding your post correctly. The Edelbrock would only be legal for S/S because of the larger port size and the restriction of no porting or port mods in Stock.

This question has been asked to NHRA and the answer was you have to cut the intake side to get the CC right. I don’t think it can be done unless you angle mill and I think we know that answer

I’ve been waiting for someone to show up with these heads in stock. 185 cc’s on the intake side. Who is brave enough. According to the blueprint specs they are legal but the only way you could get to the right cc’s would be to weld them up and port them.

It's listed as a Replacement Head for Stock in the Classification Guide????
