Wow, talk about a VERY informative thread.

He is correct about getting a different head and the power potential of an engine, based on head flow numbers. You could reduce friction and rotating mass to make more power, both are a very good idea at the power level you are wanting to go to. But better heads will make a big difference. If you want to stay with a inline valve head you should look at one of the better Victor heads or the CFE head. Both will cost a large chunk of change to get them ready to run. The Yates heads can be found used for less money, than building a set of new wedge heads that will flow enough to get well into the 9s.
As for Hamilton's engines he has, two. Both use Yates heads that probably came off of Craftman truck engines. The ports are actualy quite small for the power those engines build, they are very well done.
If you truely want to go that fast with a small block I would definetly recomend you get a good aftermarket block, one with at least a 4.125 bore. A 4.155 bore would be even better. You will get increased flow from your heads, no matter which head you use and more cubic inches. It will also be easier to make compression with more cubic inches. You should be able to build 13:1 with a flat top piston if you have a large enough engine and a small enough chamber. A flat top piston will be lighter, which will help it rev faster. Another thing if you are not already running cleaveland mains, buying a block with cleaveland mains will also help prevent burning up the main bearings and reduce friction.
So you car was running good a Pinks? Your car must be loud enough that it distored the sound on the video, because the sound on the rest of the video was very good. When I first heard the sound on the video, I truely thought something was coming apart in my engine, but after listening to it multiple times and comparing that video to others of my car. I concluded there was no way it was my car, partialy because of the sound vollume and it did not sound like that exhaust was going through an X pipe.
The source is also corrrect on how much power you will need to run the numbers listed. The hot street and street bandit cars make over 900 hp to run 8.80s, I think some of those cars are getting close to 1000 hp.

The C4 is not as bad as lots of others however it is time to consider a
Glide or Turbo 400.The C4 will be on borrowed time on the hose.

I would think its on borrowed time with the required RPMs its going to take to run those times even on the engine alone . I am not an expert on C4's but have been told 7000 rpms in high gear is just about all they can take . Some get away with it while most do not .

[Sonic Blue 85]

The C4 can handle that level of power and the rpm, but with a 2.46 first gear the car will have a tendancy to do some big wheel stands. Dynamic does make a 2.20 first gear to help tame the launch on the higher power cars, such as NMRA renegade cars. But at that power level a glide would make life easier.

These are the heads you need to make some serious steam with your SBF ......

THANKS guys for all of ya'lls input. I appreciate it.

No joke. It's cool to see a bunch of our Sponsors helping out with valuable info... even though they might not be doing the work on this car.

UPDATE******Change of plans

After thinking and talking with my machinist...I have decided to stay N/A. My cam profile would not be ideal for a N2O set up, so rather than changing things...she will stay N/A. There are a couple of different tricks up our sleeves to make some more power.

Stay tuned for details.

UPDATE on Purple BUcket rebuild. The heads are done, new Manley rods have been ordered as well as custom Diamond forged pistons. I am also installing splayed 4 bolt main caps for extra strength and reliablity.

The piston will take approximately 4 weeks to make and the crank will take approx. 3 weels to fix. I also upgraded to heavier valve springs, 3/8 chromemoly push rods and a few other goodies to reach my HP goal.

Will keep ya'll posted.

a sunset racecraft powerplant with a glide stuff'd in that stang would be a hell of a combo.

^^^^LOL. She'll be back at SAR sson, bro.

So what is the goal NA ? Just kind of curious to see if you end up where you want to be or not .

Not really sure as far as HP. After looking at how the motor was done, etc...I think the dyno sheets were inflated. Now, when it comes to ET's....I am shooting for mid 9's.

[1SLO85]

UPDATE


The crank is shot....4 cracks. So, we ordered a new Lunati 4340 forged crank. DAMN IT.

[thesource]

That sucks .......

Yeah, it was kinda sketchy if the crank could be saved. Oh well.

[thesource]

With the kind of abuse you are going to put that engine through , its not worth the risk . So what else is being done to get the needed horsepower to run mid 9's ?
