600 hp small block stocker
 

Just a question are there any small block stocker that make 600 hp and is it possible to get that much power out of one with rules the way they are.Not talking about the turbo and supercharged engines.I would think a cleveland could make 600 hp as big as the cylinder heads and valves are.

A new COPO 427 is north of 800

Re: 600 hp small block stocker
 

There is nothing small about a mod motor. It's like ford decided to see just how massive 281 cubic inches could be

Re: 600 hp small block stocker
 

My guess is the 428sbf 2010 CJ would work. 352 sbf would be close.

Re: 600 hp small block stocker
 

2003 WinterNationals, the first year/race for the EFI classes, Al Corda went 9.97 in his '00 LS-1 Firebird A/FIA (the first, and maybe still the only small-block, non-FX Stocker to run in the 9's? Might be one or two other LS-1s that did it). How much power would an LS-1 need to run 9's? 550-600? More/less?

Re: 600 hp small block stocker
 

Doesn't take that much.

Re: 600 hp small block stocker
 

A lot less. Currently, factored as it is, it only has to weigh 3250 or so in A/SA.

Several LS powered cars have run in the 9 second zone in A/SA.

A lot of people do not realize what it actually takes to make 600 HP. None of the traditional small blocks can do it in Stock Eliminator trim. The crate motors, with high lift roller cams and big throttle bodies are another story.

We get it, your a fanboy of the new fords

Re: 600 hp small block stocker
 

Chad, sorry but he said Cleveland, I assumed that was a Ford reference. Maybe I need a better GM education.

Re: 600 hp small block stocker
 

We get it Chad. You hate the Fords :D

Re: 600 hp small block stocker
 

675 :eek:

Re: 600 hp small block stocker
 

There is more to it than having big port volumes and big valves.

Re: 600 hp small block stocker
 

"675" -- So you're telling us that your D/S Mustang Boss 351 is going to run 9.80's at 3550, LEGALLY! Dream on. I'm sure Kuntz and Keith Kraft would be real interested to be there for the teardown.

Re: 600 hp small block stocker
 

C/S... 3365 I bumped it up a class and yes it will, some of you know me, some of you don't...now, the paste is out of the tube....if I can ever get the car finished.... Did you know that putting toothpaste back in the tube is next to impossible, but running deep into the 9's LEGALLY is not...wait, got to have a good working car though

I will sell you the motor

carry on

Re: 600 hp small block stocker
 

yes, there is........

Re: 600 hp small block stocker
 

Yeah, well at 3365 it has to go low 9.60's in C. I don't care who knows you or who you know, I said, "LEGALLY". That means you don't get to run a 15 to 1 piston with the right Number on it, and a deeper valve relief to support wild .050" specs on a huge cam. That's ONLY six tenths faster that the fastest C/S car so far this year and two tenths faster than the fastest A/S car. Apparently all those guys are stupid.

Re: 600 hp small block stocker
 

Once Upon A Time...Many years ago...
There was a very fast 1971 351 Cleveland in Division X...
Got torn down many times and everytime it got torn down, the driver will change the limiter and go another 10th quicker just to make NHRA go crazy.

One day, I got a call from NHRA tech asking me if there was a way or method to shrink cast iron. So, I ask Why?

NHRA had gone and procured a virgin set of Cleveland heads with the same part number used by the offender. They had the cylinder heads prepped with a legal valve job and appropriate parts.

When they poured the runners, the numbers were way smaller than the numbers they had recorded on the racer's cylinder heads. They could not figure out what had taken place since they had also measured the width of the cylinder head to make sure they had not machined the intake and exhaust surfaces excessively to maintain the volume numbers. :o ;) :)

Re: 600 hp small block stocker
 

No disrespect to anybody but I probably turn my stuff a lot higher than most, the cam is right and the compression is right according to what the book says. the valvetrain....:eek: gonna hurt some feelings

I am not throwing away money just to bracket race, I have one intention and one intention only...that is too set records, and since there are no other Boss351's out there to hurt anybodys feelings I don't see a problem

BTW, we are still searching for more power there is a lot left to rub on......did I just say that?

A well respect cylinder head man said once.....the two hardest classes out there are Pro Stock and Stock.....

Besides that......90% are convinced that fords can't fall out of a tree anyway...why ya worried?

Re: 600 hp small block stocker
 

What does LEGALLY mean? I am serious and would like a simple clear answer.
ALL brands have some secret underrated combo because of typos, bogus superseded parts, cam specs etc. etc. Are those combos legal or accepted?
Is there a difference between legal and accepted? For example somehow it is legal/accepted to run a transmission with more ratios or speeds than originally produced for one brand of vehicles but still Not legal or accepted for others.
One last question,Because it was mentioned in this thread. Is there a spec for location, radius and depth of valve notch on stocker pistons? I have seen machined notches on accepted pistons that were kind of generous.
Sorry to hijack this thread but I believe these questions are relevant. Louis Jeffery:)

Re: 600 hp small block stocker
 

In stock trim? Bullshlt!

I know exactly how much a Super Stock Cleveland makes, and it's not much more than 675 HP (with flat tops or a dome).

That's a 9200 rpm Cleveland with welded and ported close chamber heads, custom manifold, kick-out pan, roller cam, shaft rockers, light pistons and pins, etc.

You either have your numbers seriously confused or you need to find yourself a new dyno......

Re: 600 hp small block stocker
 

Always good to have more Stick cars out there. Welcome to D!

Re: 600 hp small block stocker
 

So....what makes you think I don't have a 9200 rpm flat tappet, Cleveland?

The heads, pan, and manifold are as the book says...the manifold as is...is killing the motor, in SS trim it would make a lot more

I will concede the valvetrain is pushing the rules, but most record setting combos do.

No disrespect, but, just cause you can't do it don't mean somebody else can't either.

Re: 600 hp small block stocker
 

No, not that I am aware of

Re: 600 hp small block stocker
 

The 302 Coyote will do it, no need for all those big cubic inch small blocks mentioned above! :D

Re: 600 hp small block stocker
 

Whatever you say.

Why don't you call Kuntz, Holbrook and Lawrence in the morning and tell them about your secret combo and how much power it makes. I'm sure that they could all use a good laugh to start the day.......

Re: 600 hp small block stocker
 

No need to, I make my own parts but, you do know that it only takes less than 300 cfm to make that kind of power?

It don't take welded and ported heads to do that. well...on some brands it does.;)

we just wait and see what it runs

Re: 600 hp small block stocker
 

675 is way more than the best 396-375 makes. You're full of it!

Re: 600 hp small block stocker
 

With 675 hp, you should be able to run 9.50s at 3365 in C no problem.

I think this is an "I'll believe it when I see it" situation, but I'd like to see it!

Re: 600 hp small block stocker
 

GEEZ Jerry tell them what you really think,but that's about rite.

Re: 600 hp small block stocker
 

Was said car totaled in accident at Speedworld?

Re: 600 hp small block stocker
 

You must be planning on some really high numbered gear ratio to get that monster thur end,with a 30 tire.And i'll be waiting to see and hear this one.

Re: 600 hp small block stocker
 

yep, not sure what's going to work but we starting with the 3056ST's (29.5)....I think I did tell you a little about the engine combo several months ago, I might have gave out too much info;)

Re: 600 hp small block stocker
 

When and where is this car going to make its debut?

Re: 600 hp small block stocker
 

Lou,

Yes there are specs for all that. NHRA tech has them and uses them to certify pistons for the accepted list. Although they don't give cc volumes for all flat-top pistons with notches, they do for all the flat-top Clevelands. The Chevy pistons are hit and miss, but if you want to look at the blueprint specs for the 1970 Chevy engines, you'll see lots of volumes for flat-tops. Bill's engine has domes so no valve relief spec would be given, but they have it at NHRA. Whether they'd want to enforce it as a minimum spec for compression or a maximum spec for cam fitment would be up to them. Maybe I should ask NHRA as we run an original Boss 351 Mustang (so you're wrong again Bill as I mentioned our car on one of your first threads). We don't race it MUCH or HARD, because it has the original #'s matching block in it but yeah, you would be hurting our combo.

Jon,

Yep, that's the car. I helped work on it a couple of times when it was up in this area. As far as I know, the replacement version was sold to someone on the East Coast but hasn't been raced since sold.

Re: 600 hp small block stocker
 

My pistons are on the list, but I am having a new set made with some improvements done to them, As far as I am concerned, I can read the book and that is all that matters.. not what somebody "thinks" it says

Jerry, with all due respect and I do admire an all original car, if you are not going to run it hard, you might as well stick to car shows and don't tell me what I can and can't do with mine.

Kris, the car has been sitting in my shop stripped to the bone for several months while I debate which direction I am going with it, most likely its getting the 25.5 treatment so when I get tossed out I will just step it up.

Re: 600 hp small block stocker
 

Good luck Bill. Go get em. :) (from another Cleveland racer)

Re: 600 hp small block stocker
 

Jerry,

I was on the starting line that morning when it happened. Nasty is all I can say! I always wondered what happened to the replacement.
