Here's the problem.
I have DSS on hold (LB is paid for). I told them I wanted to go N/A after starting with the concept of a supercharger capable engine.
The reason for the change of heart..$$$$$$.

My long block is over $8k, then there are the fuel rails, injectors, intake, TB & MAF, ETC. ETC.
I see the N/A engine, drive train, Paint, and chassis mods running me around $14k-$17k.

If I go the supercharger route, it could push $20k+ quickly.
So the problem is, I am impatient. I want my toy now.

If I build N/A, I could have it together by June.
If I go supercharger, it could be a year from now.

The N/A will run 450+hp at the flywheel with 10.8:1 compression.
The S/C version would be over 725hp+ and put the car in the 10 second range.

I have spent a lot of time looking at both, picking parts and adding costs.
I like the thought of a Kenne Bell sitting on top of a fully tuned engine and chassis, or maybe a Novi 2000, but $$$$$$$.

So the questions are;
Is it worth the wait?
Would the N/A be more streetable and have a longer life?
Wouldn't The N/A motor work better for long distance runs with the club?

What is your .02 on this?

It all depends on what you plan to do with the car. If you mostly want it for the street, show, and not the track then I would go naturally aspirated especially if I had 450 plus horsepower. :thumbsup:

How fast do you want to go, depends on how much money you are willing to spend. The NA route will live longer depending on how much rpm you run and how you drive it. SC will live shorter depending on how much boost and rpm, air/fuel, etc., but if you built it for a power adder, put it on there and run low boost, turbos are really popular these days. Trust me, with all the power adder cars out there, you aren't going to be able to hang NA. Maybe a big shot of nitrous would help with that.

It's the cost of an S/C and upgrades to the car so it can handle the power that I wonder about. But, I guess if I am going to rebuild, I should go for the gusto!<O:p></O:p>

Thanks for reading this and your input!<O:p></O:p>

As stated earlier it all depends on what you want to do with the car. If you are looking for a hot street car and some dragstrip runs which your comment about the 10 second range implies then I would say go the SC route. A well built SC engine with a good tune can last as long as a NA engine. The SC route you can have a flip chip, do a pully swap and rip on the drag strip then flip back and switch the pully and cruise on long trips.

If you want to do any open track events then NA all the way. SC engines just don't seem to handle 30 minute sessions well with out some major cooling mods, oiling systems, etc that is just going to run the $$$$ even higher.

Which ever way you go good luck and have fun!!:thumbsup:

From your descriptioin, the block is stock I assume? Just the DSS preped stock block to their level 10 or 20. If so, then you should stay NA. If you get the hp you say, 700+ SC, then the stock block will not hold up to that power, especially supercharged! If you are serious about getting 700 hp, then you WILL need a aftermarket block. Stock 5.0 blocks are good to around 500 hp before they start splitting.

Thanks.
I have decided to go the N/A route. I will post pics when the long block arrives and of the build. Once the the decision was made on which way to take the motor, the rest of the parts fell into place fairly quick.

Well I am stoked or should I say stroked, 347 STYLE.
Motor and parts arrived today.
Here are a few pictures.

So far I am pleased with the service and quality from DSS.
