Best way to go 9's on pump gas?
 

In a heavy car? Like around 3700 pounds with driver. Big cubes and spray? Turbo?

Well if you want big power on pump gas... big cubes is the best way to go. The 572 crate motor is out now.

But im not a fan of nitrous.. but thats me.

Spray or turbo will work.

Spray turbo and a built 427 will work.

heads, cam a good driveline along with forged internals and a 250 shot should put you on the edge. I'm hoping to go 9.90 with a setup like that this season

408 and a little juice! Mine is 3600# and I'm about there with a little fine tuning in street trim. I'll be there for sure with slicks and open exhaust. And I'm not really spraying that big of a shot.

Bigger cubes makes it much easier , but it can be dne with a stock sized motor also :devil: Mine is not quite 3700 but still heavy.

I think the 4l60 will be the biggest problem when trying to go 9's @ 3700lbs.

Good luck with it :drive: :)

Yeah a 408 WITH A GOOD SET OF HEADS and a 200 shot would put you there all day long with ease. You should worry about your transmission first..

If I can get the car close to that level I will go TH400 and lighten the car more.

why do you want to stay on pump gas?

More than likely to retain streetability. That's the only reason I'm going to stay with pump gas.
I'd say forced induction would be the easiest way to get into the 9s on pump 93. A turbo would be the way to go, low boost for the street and turn it up for the track. It's even easier when you add a 2 stage/progressive methanol injection setup to the mix.

At 3500#'s I went 9.7x's multiple times in 1500-2000 DA on pump last season with 427 ci, and a 150 shot. Plan to be deep in the nines this year and on pump still.

If I had it to do it over I would of built a turbo set-up, but 400+cubes + n20 will easily get you there.

Turbo motor stock size to 427, low compression 8-1, run the meth/water injection, 2 stage boost controller, also a turbo motor is much easier on parts than running a motor and spraying it with a 200 and up shot of nitrous. Best way, turbo, cheapest way, nitrous. How long will a motor running to 5500 rpm with good parts, pretty much forever. I lived by kenny duttweiler's shop and have seen a ton of small blocks making 800 hp on pump gas @ 5500 rpm, with motors that are not even close to as good as some of the LS1 stuff today. When you can make 1800 horse power with a motor under 300 cubic inches, I'd say it is the way to go.
