who has the "Magic Heads"

When the rules were written it was the only thing that would compete with the chebby stuff. I have personally seen some of the new chebby edelbrock stuff go in the 525-530 range.

How about we do like some tractor pulling classes and put an RPM limit on them and give them the chip to do it.

so how are A heads better than BC's... I thought they were more like a C head type deal..

Not to mention anything chevy has like 5000 intakes, and all kinds of block options...

they are winning more races ......


put a 500 shot on a 510 cfm a-head and put a 500 shot on a 550 cfm Big Chief which one is faster ? on a 10.5" tire

That sounds a little odd... But ok.

A ten stack thats nothing to these guys who can afford it especially when the purse is 3-4 times that.


So no one is admitting that they are running the "MAGIC HEADS" here?remember this is on a 4500 single cast intake

I'm aware of the rock'n conventional bbc heads. The conv. bbc heads are defined in most rule books as something not less than 23*ish valve angles. Otherwise there is not much "conventional" about them. One inch lift cams etc. are required to make them the most effective. A set is coming down this way for a bbc unpaved track vehicle. Two things you can count on......I'll get them on the flow bench & a very good set of C460 heads/manifold could be cheaper.
Magic and money both start with a "M".

my IDT heads flowed 498 @ .900 on a 4.500 bore.i'd think on a 4.625 they'd do more,which IDT said 511 on 4.625. one thing i've heard the local chevy guys talk about is needing a big core cam.they spend a lot just to have a cam of much size.lol. i heard of one guy who took a chevy/olds block of some sort,aftermarket anyway,and had the headbolt holes located for EX514 heads.then he got a chevy intake,it was cast i know,and cut it all up to fit the ex heads.the chevy guys were bitchen about it having ford heads.lol.....and it wore their asses out at the truck pull too.

Like Al Neal said.......how did it run?
