Wait aren't you worried about spinning it that hard...?

Don't know if you were being sarcastic or not..

Please tell me that part about it having a Flat Tappet cam is a misprint! Why would someone build an engine with all the rest of the parts listed above, yet not run a roller?

Maybe so they don't have to change valve springs as often? Depends how much "street" is in the street/strip.

They built me a flat tappet motor just for that, mostly street, some strip tease. No springs needed yet.

I don't know about Best but I always start pulls on 110 octane or better until I get the tune right. A dyno pulls a motor harder than any car or racer can ever imagine. If you're off just a little you can push a head gasket or blow a piston in the blink of an eye. Better safe than sorry.Dave

That's pretty stout for pump gas compression and a flat tappet!

IMHO That would make a great bracket engine as well. Change oil and plugs and check the lash in the spring and run it!

I'm sure inquiring heads will want to ask in what ballpark this falls in budget wise. Great heads.
BEST makes great engines and great HP even with less grade heads.

I like the idea of engine builds being put out here but it would be far more interesting if some of the questions posed here were answered, as it's always nice to hear the professional's perspective on what works and what doesn't and why.

If it really has 12.5 CR as mentioned in the build spec, that doesn' t sound like "pump gas" to me.

Re: 540 Low Deck with 440-1 345CNC Dyno Results - 09/20/14 05:09 PM

I must have missed where it said pump gas. All I read was street/ strip

Re: 540 Low Deck with 440-1 345CNC Dyno Results - 09/20/14 05:19 PM

Depends on a few things. bleed off, Quench and aluminum heads make for a more civil compression.
Mine is 12.5 and I can drive it (not race it) with the sh#t they call gas nowadays, but choose not to since all that STUFF added in makes for a dirty sick carb at the end of the day.
I just mix with 100 unleaded that can be bought at some stations with the good Sunoco 112 grape juice as I call it.

What bore and stroke did you use on this build?

Nice build.

I`ve driven my dart on the street w/local 91 stuff and it was fine but wouldn`t even consider racing that way so I run VP-101 from the pump at Arco which is 97 octane and hopefully is consistent from batch to batch..............

What's it like from, 3000 to 5500????

Dwayne, I would never make a pull 2500 under peak Tq. Here is a sheet from 4500 to 5500. It drove real clean from 2500 to 3500 with a 100 lbs on it

And curious about the leaner that normal afr`s......... Bad azz hombre though.

The AF will vary depending on the cam, comp and fuel. Don't be locked in that 12.75 is the best

Any chance you can post the results of Joe's W5 on the pump after you have it on there? Looking forward to seeing how it does with the new heads on it.

Sure Don as long as its OK with Joe. Its on the dyno now and we will pull it on Monday

This is living proof on how much power a pump gas motor can make with decent parts What bore and stroke did you use on this build? It looked like the motor wasn't done making power at 7000 RPM I normally pull the motors until I find peak HP

Cab, not pump gas we ran VP 110 our customer likes the smell of race fuel lol! its 4.500 bore and 4.250 stroke. we did pull it higher and it was at peak at 7000

We didn't need to run a roller to get to our HP goals for our customer. He is a older guy and wanted something that would require min maintance

Out of interest, did you try different carbs or spacers ?

We have done a lot of testing with spacers, on a cast 4bbl intake bigger is better but those dam hoods keep getting in the way

Do your results vary when using supersuckers and by bigger i assume you mean the 2" ones. From other posts i've read, the feeling seemed to be that head limited motors benefitted more.

You got it, low maintenance and more street than strip

Yep the 2" 4 hole work good, gives the fuel more time to turn down the port rather than hit the floor of the Manifold. None of the Mopar Intakes have enough plenum volume

Curious about wheather or not you`ve done the 2" dominator adapter deal on a 4150 manifold and what you`re results were.........

With a 280 @ .050 cam in at 110 , that equals a 9.39 dynamic CR, cranking compression of 196 psi.

Nice results.
Even with the 4150 carb and flat tappet cam it made great power. And I agree the owner could drive it on the street (part throttle) on pump premium gas. Race gas for full throttle would be recommended just to be careful.

I am sure it will spin the tires on the street at less than full throttle!

Exactly what I have done.
