Yea sorry about the post topic.

As for what I will be doing with the car. It will be mainly for the street, and will probably get no more then 9-15 runs down the 1/4 in a year.

Thanks for the input. I will start purchasing the cam and valve train, and go from there.

But I will build a short block eventually for a blower, Ive always wanter to supercharge a v8. Not buy one blown from the factory, or a car that had one allready installed. I wanted to do it my self.


So my question is, why are there a bunch of LT1 guys that spray 150 shots on their stock blocks, for a while before they go boom? Wouldnt nitrous cause more wear and tear over a intercooled supercharger system? Just wondering.

Mainly it's in the tune. What causes ringland failure is detonation. It's very easy for either nitrous or a supercharger to produce a lean condition in the motor which kills the pistons.

Also, a nitrous setup is usually a little easier on the motor because nitrous oxide produces a cooling effect inside the cylinders which helps to reduce detonation and prolong piston life. A supercharger on the other hand simply forces more air inside the motor. And the more air you force into something the hotter said air becomes due to it being compressed. Excess heat leads to detonation which leads to piston failure which means rebuild.

 

If you want to put a SC on you should do the heads and cam anyhow...along with the botom end!!! All that extra air will need to flow out faster after combustion, so a good port job and headers will help.
I went with a good head and cam package. You can see what I did in my sig. With this set up, I have beat a SC TA four times!! He wasn't very happy seeing as I spent just over half of what he did and still beat him good!!! He's running a Vortech at about 7lbs (around there).
A good cam and head package along with a good tune will get you good power and torque!!

 

Or run a bunch of spray

 

Im gonna hop on the HC combo. For the money it will net you much more power. The only downside in doing this would be the loss of gas mileage. A SC will not hurt you as much on gas as a big cammed NA setup will. Im not sure how much money you have to spend or what your financial situation is, but i always recomend that you do things right from the bottom up. Dont start forcing air through heads that dont flow well enough to handle it. Get the heads ported out w/ bigger valves. Cam it pretty good and go from there. On a rather mild H/C NA setup if it is done right can net you about 400 rwhp on the stock bottom end.

So if i were you i would go H/C and go from there. H/C needs to be done with a good SC anyway, so might as well get your feet wet.

As far as i see it, the limit (that i would go) on the rear end, tranny, and bottom end is roughly 400 rwhp. That can be done without going FI. So if it were me i would ask myself, 400+ or -400.

Mike, how about heads, cam, and a bottle?
