Highest flowing sbm heads?

No, I haven’t.
not bragging , but if anyone wants to take it that way, Oh well.
I had a 70 Duster street/ strip car. Full interior including back seat. Had two Kirkey seats, otherwise interior was bone stock.
Uncut, untubbed, not even mini tubbed, super stock springs, it was a true sleeper.
it ran 9’s with a 700 lift roller, 13 to 1 compression, at 3350 pounds with my 300+ in the seat. Very good W5 heads.
that car was honestly fairly legendary in these parts, running like it did.
so frankly, I find it very hard to believe when you throw around as supposed fact there are lots of NA W2 street cars running around.
it takes an honest 650 horse to get a heavier car( like I had) solidly in the 9’s.
650 horse W2 motors aren’t growing on trees that I am aware of. May be some, but they aren’t common or I would know of them
I have one in my garage. It did 650 hp and it isn’t a stroker. I guess I will have to take your word for it. Plus my W5 motor 436” 9:1 compression breathing through turbos with 33” tire 3.70 gear and a 2500 stall ran 10.30/138. I don't think you are bragging at all. Not all motors are created equal.
I don't think you have a clue what your talking about either so we will just agree to disagree and I don't like your cars either so go back to your west coast left wing lunatics who will coddle you and tell you how great you are because your not gonna get that from me
Dude you need help. Every thing you say has been debunked. You attack everyone like you are the end word in everything. You really have no quality information on anything. You go on tirades on the same posting, posting over and over. You assume things about people. Then you make statements like this. You have really shown what is at your core. A bitter, jealous, vindictive, insecure, narcissist. Kindly go somewhere else where you fit in. No one wants you here. Take the hint.
