SB2 in a super late?

[fastlane99]

Sounds like I better pass if the motor is that underpowered from other sb2s. Thanks for the info guys.

If I remember correct, I think Bill Hendren posted a couple of years ago that with a Brinn and a QC he saw 19% through the drive train. I think he said 17% with a 9" Ford...If Steve ever gets on here anymore, he might verify...

you can catch steve on his facebook page bout daily!!

according to that info it has about 590 hp that is a little low but its not an exact science. comparing dyno to dyno is tough and honestly i never believe any numbers i hear until i can see the dyno info myself there are things people do to make the numbers better. what was the ambient air when engine was dyno what was the water grains in air was the motor fresh when dynoed alot of variables in there. what was the dyno "smoothing" set too? id take a motor that was truly dynoed a little low on power over a motor being "claimed" to have x amount of power just my two cent, plus if its a good deal why not. 590 will win races.

[fastlane99]

Not sure if it is a good deal or not....motor has 8-10 nights since freshened. 7500 with everything but pulleys, headers, and oil lines. Plus it will need freshened I would think within another 10 or so races.

[andy16]

id say thats about what its worth? not really a great deal but not a bad deal either unless the motor has a issue. decisions lol

You have to stay with the 360 inch limit or are you just looking for a good powerplant? Steel block OK?

Don't have to stay within the 360 ci. Looking for a good dependable motor to get started in the slm class with.

If it has good pieces in it I would say that should be a reliable motor. But some guys can tear up an anvil. Use it until you are ready for more power or bottomend needs replaced and get more cubes at that point

I'd say that engine would be just fine for starting out. Don't get wrapped up in HP numbers because most of these ridiculous HP #'s are false claims anyway. The ones that really do make the numbers hurt you more than helps most of the time. HP is good but you have to know what type of HP you want. I personally don't like SB2's in DLM.

590-600 at the rear wheels is very respectable. I have a 13 degree 430 that doesn't make much more than that on the chassis dyno and it will out drag race anybody off the corner. The only time I really need the HP/torque is when it's at a really hooked up track. Probably hurts more than helps when it's slick or dusty. I'd say a shorter stroke motor is probably way easier to drive on a slick track. When you get some experience swap out the crank and rods and get all the torque you need.

Why is this? Harder to drive due to higher peak power rpm range? I have access to an ex nationwide 358 sb2 but dont want to dive in if its not a good piece for dlm racing. What do you guys think?

If the cam hasn't been changed don't try running it on dirt.

An inline valve engine is much smoother. The PK torque rpm on most SB2 engines are too high for dirt racing. The worst thing on dirt is running an engine below peak torque when its build to make power past the peak. Thus the reason Perfconn said change cam first. I'm not saying they can't be competitive or anything like that and they don't make power because they do. Its just that valve arrangement loves rpms and hates not being rpm'd. Plus they are a little heavier top end. I'm in no way saying they can't be made to work.

Anyone ever run one of these in a super late? Advantages? Disadvantages? I have access to one, but wasn't sure how they would do. Dyno sheet shows 680hp. We run small tracks that slick off....any advice appreciated.

Thats low HP. We had a 358 steel block with 18 deg heads that made 740 back in 99'. Matter of fact I still prefer the 18 deg stuff. JMO

Split the difference!

How would 15 degree heads work compared to SB2's and then to 18 degree heads, this would be on a 421. I don't really want to know HP numbers but more about how a dlm would drive with each set of heads on this motor?
