Don Terrill’s Speed-Talk

Good lucky Mark.

Tuner, sent you a PM

Good luck, I like to follow this type of stuff

The guys I work with made more then 770+Hp with stock block and stock 440 crank with old entry-level B1 heads. I believe Don ran that combo for 7+ yrs as well. https://www.rollingthunderz.com/race-cars_1970-duster_image-gallery.shtml "Edelbrock 440 Intake Manifold being ported and flow tested t...

Update, getting a bit of info on YB.com. Seems they can work well and make good power, just heavy.

Thanks, we try. But getting harder and harder every day. It's all good. Thanks for the compliment.

Why YES I am. Some back history there.

We do our own cams. But might get Jones to do one.

I can see it flowing that much. A ported GM OEM casting will go 380. My own 074s go over 380 with 2.250 intake. FYI my GM OEM oval port 215s goes over 330 with 2.19 intake. There is more in then too.

Will get them flowed when the motor cones out.

Mag, there is enough flow in those heads at @.500" to make 700Hp. That's not the point. Just like to see what other have done or found when using these heads. Plan is to cam this to peak about 7400 and carry another 400 to 500. I myself only had 1 engine that was all done about 6700. I hated it...

Stock 26 degree as OEM chevy is 26 not 24 deg. Intake port are NOT raise and Yes I think there pretty much as cast.

Anyone know anything about these? I aquired a set on a 454 in a car. Going to flip the car after a yrar or 2. I know there sq port 310 cc intake runner, 119 cc chambers with .600 raise exhaust, but other then that, I have no idea yet. I see they flow pretty nice @ 383 At 700. Supposed to be 2.300 in...

71 Mark, VortecPro is the one who said to me the "more bangs per second" theory and when asked about doing my oven BBc with my ported 215 ovals, he said HE would go 3.766 stroke over the 4.00 or 4.25 stroke if it were him. I speak to Mark a couple of times per year. I actually own "Le...

71vette, we would walk all over the 6500 rpm 496 with our 478 (3.75 stoke 4.500 bore) 9.0 to 1 compression bmf 330 headed cast single. Car DID go 9.0s on motor @ 3250 back in 2008. So if your in the same weight, tires car, both making say 700Hp, yet one goes 1000+ rpm more. The higher rev wins 9 tim...

I would run a version of the 290 ovals. Flotek, Promaxx or Profiler. Match with a Strip Dominator intake since relatively low peak rpm.
