If anyone needs any real world information. I've had these heads on my AMX for 3 or 4 years. With these heads, stock block and off the shelf parts you can make a reliable 650 to 680 hp. Our AMX is living proof of it.
What head castings are they? Do yall cast your own? Nice work, btw.These are our VR-200 heads that my brother and I have worked on for a while now.
In post #22 he stated they are speedmaster castings currently. So essentially, it's a ported speedmaster with there own porting.What head castings are they? Do yall cast your own? Nice work, btw.
You should try a Magna fuel 500. If you do let me know. I have a spare Alcohol carb that you can try. Just to see how your car reacts to it.I had a new best 1/8 mile yesterday.
[email protected]. Full mph faster than previous best, 1100 foot of air!
565 lift flat tappet cam, flat hood, 3330 with me. Bloomer heads.
Unfortunately, the car layed down bad trying to run it 1/4 mile. Replacing the extremely dinky electric fuel pump I have on it will be first order of business in the offseason. Should have swapped it off last off season, but any more I virtually never run the 1/4, and it makes it that far fine.
John passes away (pittsburghracer) and these fellas throw their hat in the ring. These guys have been doing their homework as well and are getting great results. The technology continues. I am impressed at how well the Speedmasters can be massaged into top notch performance heads. Someone needs a tool path to reproduce these with accuracy and consistency. Not saying that can't be done by hand but at what cost. Let a machine do the duplication.
Boosted kinda did that. He sent his trickflow heads out and had them ported a little and larger valves put in. I don't remember what he was running e.t. after but is was somewhere in the low 50s maybe even the 40s. I am personally running high 50s - low 60s with out of the box trickflow's.Not really a apples to apples comparison, your head is a fully ported Speedmaster bare head, how about taking a bare Trickflow head and giving it the same level of porting.
I wonder how these heads compare to John's ported version. We know John was all about track performance as well.John passes away (pittsburghracer) and these fellas throw their hat in the ring.

Gotchya. Thanks. I missed that part.In post #22 he stated they are speedmaster castings currently. So essentially, it's a ported speedmaster with there own porting.
I have a head porter local to me that's very good. People come from all over the country to have him do work. He did my slant 6 closed chamber head. He says all of the import heads he's seen and done the castings are pretty high quality. He agrees the details could be better, but the castings themselves are pretty darn good.

Purdy dang stout!My car has been 5.84 @ 116.6 mph. That's at a race weight of 2870. It's flat top pistons and a unported Super Victor. If you figure up the hp with the Wallace Power Speed Calculator. That's 707 hp. There's very few conventional heads out there making that kind of power.

The Trickflows are a entry level street head, not a max effort porting. What has been done to the SM casting should also be able to be done on the Trickflow with close to the same results. I'll let you know, I just purchased a pair with this in mind.Actually both are CNC ported heads.. the Trickflow is a CNC ported head.
There are several guys running 9’s with these heads in pump gas street cars. I haven’t heard of anybody running remotely close to that with trickflows.
Heck, even my very conservative street strip car with a small flat tappet cam shows 602 horsepower on Wallace based on time slip.

Like I've said in other post. Theirs lots of good head porters out there that can work wonders with SBM aluminum heads. The thing about the BPE heads is that you can buy them, have them shipped direct to you. Take them out on the box, install them on a properly prepared short block and make over 650 hp.The Trickflows are a entry level street head, not a max effort porting.

Thems be some fightin wordsI would imagine a trick flow ported the same as the bloomers, would perform pretty much the same.
