Re: 452 Heads Question

[Joey <jake4@xxxxxxxxxx>]

in the 70's, I don't know how long Ma Mopar produced them, at any rate, we 
love them for a stock head. Another good head that might have hardened seats 
is the 346 castings, I can't honestly remember. Some years ago a buddy 
bought a set of 346's that were ported  by the Rettig Brothers in California 
and they were really impressive. The car in question was rather quick for 
the time, keep in mind that back in this era I speak of there were no 
aftermarket offerings such as we have today. I remember spending untold 
hours epoxying up 906 and 452 castings after some radical porting, 
surprisingly enough the 452 seemed to have better core strength and by that 
I mean they would last longer and not crack as fast as the same version of 
906's. I expect all of the engineers are probably going to rip me for this 
but I am merely stating the facts as they were for us. Since I am on a roll 
one of the better intakes we have found for both street and strip cars is 
the Holley Street Dominator intake with a little porting. I have around here 
somewhere some flow numbers of a test I did. One night when I worked for the 
late John Lingenfelter I decided to flow my own 440 intakes to see where 
they stood, the test consisted of a stock 67 cast iron, a Edelbrock TM-7, a 
Weiand 7512 and a Holley Street Dominator. As you can imagine the stock cast 
iron was horrible, the surprising outcome of the test was the TM-7 was 
nothing to get excited about and the Holley Street dominator wasn't too far 
off of the race bred 7512. Oh My, aren't I just a little chatty tonight!
