So i have a sb 350 been bored .060 over not stroked. I have some flo tek aluminum heads not sure which one they are(on the front says flo tek 200) has a bullet racing cam in it its a 560 lift advanced 4 degrees. Run a th350 with a 4500rpm stall converter, has a 5:14 gear. Holley 750dp a air gap speed master intake. Has solid roller lifters. Currently running 110 fuel and timing at 40 degrees. Runs 7.76 in the 1/8 mile.
compression is currently unknown. Never dyno engine so don't know the horse power.
my question is what can i do to make some easier hp without having to go through the whole engine again? Or replacing some expensive parts.

 

Nitrous...

 

Do you want to go quicker in that 1/8 mile run or more fun on the street?

 

This is strictly a race car. So i m looking for more the track

 

I kind of wonder why the cam was installed with the advance, but to answer the question, yep, NOS spray.

 

We did this to gain some more compression out of the engine.
You say that nitrous. How much spray? Not looking to blow it up any time soon.

 

This is a risk vs reward deal here. How fast do you want to go? Is it worth blowing the bottom out of the engine? Relatively low cost way to increase power compared to forced induction or going with a stroker rebuild. And usually advancing the cam gives some lower rpm grunt while retarding adds a bit of power up top. With your gearing I'm guessing the motor is wound pretty tight through the 1/8? Something to think about anyway.

 

So since my engine is bored .060 over. Ive looked for stroker kits for my bore and cant seem to find one. Do you have any suggestions on a stroker kit? And also what kind of boost do you recommend if i was to go with a forced induction setup?

 

A 0.060" overbore of a 350 block is starting to push the limits. Those cylinder walls are getting pretty thin.

7.76 in the 1/8 works out to around 12.18 in the 1/4 mile so basically a low 12 second drag car.

For 1/4 miles times, a 150 shot of NOS to a 14 second car can make it run in the 12's however a 150 shot of NOS on a 12 second car should get it into the 11's. A 150 shop of NOS on a high 10 second car won't get it into the 9's.

Just about any good none worn out V8 engine should be able to handle a 150 shot of NOS. For bracket racing however, there comes a lot of drawbacks. A 10 pound bottle activated during the entire run, should get you around 7 passes on a bottle but every time you use the bottle, it gets colder and a colder bottle has less pressure. Less pressure means less NOS is being injected into the engine and you make less HP. To use NOS, you normally would use multiple bottles and a bottle warmer to have the same bottle pressure on every pass. Bracket racing is all about consistency. If your car slows down on a dialed in pass, you lose. Don't forget, you'll be constantly paying for bottle fills after each race weekend so the HP increase isn't paid for when you buy and install the kit.

The cheapest way to go fast is to remove weight. Since it's a track only car, remove everything not required for speed or safety. Same amount of HP will move a lighter car down the track faster than it will a heavy car.

 

Yes i knew of the weight rule. I get the Nitrous thing as well. Then the next question is what about a vortec super charger? How much boost can i run? What would i need to gap the rings to, to make sure i dont have a problem there.

 

Want to supercharge your engine? Might as well strip it down to know what's in it first. You're running a high octane fuel. Is that because you have high compression pistons? Octane is the fuels resistance to detonation. If the engine doesn't ping/knock under acceleration with 92 octane fuel, then the engine won't make more power with 110 octane fuel. Generally a boosted engine wants low compression forged pistons. Without knowing what's in the engine, I don't think I would push more than 5 pounds of boost.

40* timing is also a lot for a SBC. You might want to experiment by dropping the timing down 2* and see if the MPH increases. If it does, go down another 2*.
