Too vague of a question.. specs like what cam, turbo, weight of vehicle, etc.

I cant see why mid 9's cant be done. Probably even faster on the StageII's

murphster's champ alums are out of the box

10.19 129 @ 22psi
224/224 roller, 155 rockers ,70mm, ta headers,champ ported stock intake, cotton fmic ,almost #3700

im just wondering in the long run if a untouched aluminum head can take you further then a ported iron and more reliable i guess...

pacecarta · 10-30-2009, 11:50 PM

champ alums and reliable

,, irons for street ...alums for race only

VxTurboxV · 10-31-2009, 12:31 AM

Went 10.70 @ 126mph on factory stock 8445 heads.

pacecarta · 10-31-2009, 12:41 AM

yeah 10.7 126 sounds impressive but he plans to run in a regal chassis so take your impressive numbers and toss them at a car that weighs 3600# and that 10.7 would be a 12.6 at 108

Walt Judy just went 9.3 and set the TSM record with stock ported iron heads. He also has a stock ECM with Max Effort. I've seen alot more Champion cracked aluminum heads then ported irons. For street/strip iron is the way to go.

already been 9.91 with the irons but always pushing to the edge and would have went a 9.7ish last time out had the head gasket not blown pushing the cars motor..just looking to upgrade to something a little better so i dont have to put the car on the edge all the time...

In the 9's I'm sure the Champ aluminums will get you an extra few tenths but I would noway label them reliable. Nothing on the motor is reliable in the 9"s

1985GN · 10-31-2009, 09:05 AM

lol you dont need to tell me that. im just debating on porting them before putting htem on or not if i go that route in the winter. with money becoming tight now im probably just gonna throw them on for now and let it ride.

Why not try the TAP heads and see if they don't last longer?

Ya noticed that huh!

Although there is less than an 800lb difference. So I doubt you'd loose 2 seconds. More like 11.56 @ 115.85.

Maybe take a tenth out of that for "brick like" aerodynamics.
