I agree that you should boost it instead of running nitrous. If your looking at a 20k budget you can afford the boost and you never run out like you do with nitrous.
It shouldn't be TOO much of an issue to get into 11's with a single cab

You will definitely want a 4l80 transmission See our sponsors on the right. I'd recommend Finish Line Transmissions.

If you want to build a set of heads talk to West Coast Cylinder Heads (also to the right) they can tell you exactly what you need.


Forgot to let you know that the search sux when using numbers so 5.3 4.3 6.0 doesn't work.
v6 i think might work.

 

And don't forget the fuel pump.

 

I would be interested to see your results from the T56. Anyone I've spoken to about the 6speed loves it in their truck. Plus you can run 4.56 or 4.88 gears and still have some highway milage. I also agree with the built and boosted engine, turbo or supercharger. I'd recommend the Magna Charger TV2300.

 

would i be able to build the engine correctly and still run turbo?


and t56 is a yes if possible.

If its not way too hard it will be in there.
