I have finally received my issue of car craft. The castings tested were in fact D3VE's. :evil:
After reading the article it is painfully obvious that...
...The primedia rags have their noses buried so far up mother edelbrocks behind that they have to come up for air every 3 minutes.
...The article was nothing more than a glorified advertisement for the edelbrock RPM castings.
...they did not even try to find any information on proper porting technique for the iron ford heads. (If you google D0VE porting instructions or D3VE porting instruction my website is the first entry).
...They did not employ standard porting proceedures outlined in previous articles that states the majority of gains to be had are in the bowl area just above the valve seats.
...They did not want the iron heads to show up the RPM castings so they did minimal port work. Whats more they did some work that actually hurt the flow they could have gained. Namely raising the thermactor roof bump, unshrouding the chamber wall and radiusing the chamber to seat on the short turn side of the valve.
We all know that home ported heads following my instructions usually net 300/160 to 170 cfm with small valves and 320 to 330 / 170 to 185 cfm with large valves. I have tested many a pair of home ported castings to come up with the above numbers as have others here.
The costs they outlined for rehabilitating a pair of iron heads seem quite out in left field to me considering the fact that I sell a fully rebuilt and max ported pair of D0VE heads for that amount shipped to ones door.
Finally the comparison was an apples to oranges test because they did not bother to use 2.19" / 1.76" valves, which the RPM's are equipped with. The RPM exhaust numbers are with a pipe and I have numerous D0VE castings that easily exceed 200 CFM with pipe.
I ask that all of you that have experience with these castings either home ported with no instructions, home ported with RHP instructions, professionally ported by RHP or anyone else and flow tested to email carcraft at [email protected] and tell them what you think of the article. Please send me a CC or carbon copy of the emails to [email protected] so I can keep them on file.
I would be willing to put up a pair of my large valve 345/200 cfm D0VEs against an out of the box pair of RPMs any day.
Lastly in my experience the RPM castings would be my last choice if I were to purchase an aluminum aftermarket casting. I have ported all of them, SCJ, P-51, TFS street and cj, BT and RPM and know who is who in the zoo as it were.
I am fully aware of the advertiser politics involved in the mag business but that does not excuse this glaring misrepresentation of the BBF iron heads.
