Looks really nice Tony and that cam did better than I thought it would. That engine would be a real handful in a street car. Probably blow the tires off of most anything.

The intake manifold vacuum is telling you that you need a bigger carb at WOT. If you were local I'd loan you my "true" 950 Holley just to see how it works. Most of those 1000 cfm carbs are actually an 850 venturi.

I'd also loan you a set of 2 inch dyno headers which would probably pick up the torque. 2.250 headers are huge for that engine.

I just looked at the torque curve...high and flat. Wow. Max numbers are cool, but put that engine in a car that hooks up, floor it and the engine just won't stop pulling until you get off the throttle.

If the heads are good enough, large duration cams aren't needed to crutch the airflow.

Andy's right, that engine needs a lot more carb. There's a lot more power hiding in that engine.

Congrats Tony! Nice job! Glad to see you're still building some cool stuff.

Thanks John. Don't have nearly as much time as I used to, but I'm still in the game!

Great numbers Tony! You'll be happy with that cam. I'm sure you'd want a bigger one in a max effort engine but you did the same thing I did and built a nice street cruiser. I have plenty of old 9 second time slips, I just want to drive my new Duster so I went with 500 inches of pump gas power, max wedge Eddy's, 557 lift cam, 1 3/4 headers, 3.55 gears etc. I figured I'd hate the camshaft but I don't, I love it! Very streetable and blows the tires off in any gear.
Enjoy your new motor!

Very similar to what I'm building! 505" stroker with Source heads, Street Dominator intake, .557 cam and 10.5:1 CR. 2800 stall and 3.55 gears.

3287 lbs. for the car so it should be fun!

Great minds think alike! Did you guys call each other up first? Bob, cool that you've been there done that, and got the 9 sec slips to prove it. I have a handful of 10 second slips and a 10.02, but no 9's. Still on my to do list, just not the right time. You guys have a couple of killer street combos. That 557 cam may be an old design, but it works great.

When you gonna have it out Tony?

Wow, Nice Tony!!

So very close in all the specs to my "little" 517 Chapman Low deck Max. Sure, I got maybe a point more of CR and just a slightly bigger 264/268 @.050 Bullet HR....but you've got those 3 extra cubes! You got yourself a BEAST there, Tony!

You're gonna love it.

Well Done, Buddy!

Looks good, but I can't help wondering how different the dyno #s would have been with the expected 2" headers, instead of those 2.25" sewer pipes.

LOL definitely very similar combos, I just wanted something fun and drivable, I really didn't expect the car to feel this powerful, it's a handful on street tires.
Tony you've had some nice cars and combo's so I'm sure this one will be just as good.
