Yes this is a stick car

I will look into those Mad Dogs. What about JBA 6655S. 1.75" but claim openings for fully ported heads. Thanks for the help, Joe

What headers are available to fit 428CJ heads and power steering in 67 Stang Please. Anything larger than 1 7/8"?
Brands Please. Thanks,Joe.

is this 9000 series Scat a product item in 4.125 do you know?

Finally was able to dyno the motor and this is what I got with the original 2X4 D manifold.
After numerous pulls with the pair of 750 vacuums and re jetting we netted 619hp and 610tq. I bought a pair of 660 centers prepared by Allstate Carb with 76 jets and metering plate squared.
1st pull fouled plugs so dropped the jets to 72 with metering plates unchanged netted 635hp and was still pulling too much fuel.
Ran the carbs to Allstate and Jim immediately changed the metering plates to 72 and opened the hi speed air bleeds. I took a pair of 70 plates with me in case.
This netted 655hp at 6300 and 623tq at 4700.
Changed the primaries to 70 and plates to 70 at 38* timing and made 664hp.
Plugs read perfect and fuel flow where it belongs.

Hey guys I would like to try a tunnel wedge 2x4 hi rise for my factory cast iron hi rise heads. any aftermarket pieces available?

Wayne Sharky matched the port to the gasket yes. he ported the heads and did the valves and they flow a true 350 cfm. Great job I think. 2.250 and 1.70. Truthfully I'm getting caught up in the numbers and agree that the difference in performance for the cost of buying a quality piece for my purpose may be foolish. At 56 I still can't get enough. Still doing the street outlaw stuff.
You saw my cam specs so I've got friends taking a guess at the HP and Torque numbers before the dyne tomorrow. Take a shot?
I'm thinking 665-675 and 620 torque.
I'd love to see 700 like some folks are getting. I'm beginning to think different dynos with the same motor and you get different numbers.

How can I contact Blair to ask some questions or his website please.
