Phat-
A true IR Dominator intake while using the larger 1150 cfm carbs can only feed a 350 cid engine @ 8,500 RPMs. The late Bill 'Grumpy' Jenkins was a master at making them work on a 331 cid drag engine. Yes, there were 'some' experimental 4500 series Dominators made, but proved to be unsuccessful. That said, the original sand cast IR Dominators, as you may recall were used on 302 cid engines for Trans-Am competition. Btw, there was never any big-block Dominator IR intakes made (regardless of brand) as I mentioned, not enough carbs to feed it. Fuel injection, and two Autolite 'B' 1425 cfm Inline carbs and the rare Weber 58mm carbs will feed the large big-block Weber IR type intakesÖ.but that is a different topic.

The Corvette radiators were aluminum vs brass for the Camaro radiators, hence a little weight savings.

Thanks, Bob.  It looked like quite an impressive gathering of Penske race cars at Amelia Island.

Stahl style header style bolt pattern.  For round port heads or spread port heads.

Correct me if I am wrong, it appears there are 'spacers' between the heads and headers? Isn't this for the 'larger' exhausts to mate up...I have seen this before, especially for the mentioned round port/spread port heads, right?

Thanks for the info. Are the heads already prepped or do you have to drill and tap yourself?

MO,

The porting of the cylinder heads of that period (Lockerman, Valley Head Service, etc) utilized a large, round, exhaust exit which greatly reduced gasket area. That created a gasket/header flange durability issue particularly in the two adjoining center ports. The solution was adapter plates attached to the head flange. with a revised fastener pattern for the header flange.

I believe JohnZ said that the Aluminum radiator was also a much more efficient design which cooled better.
