450 whp?
#41
Yeah Alek's old 355" was the reason I literally ran down to my parents house just to show my father what a really bad *** LT1 sounds like. Also Bolo's car is another one of those cars that just get under your skin. I remember also running down to my fathers to show him Bolo's video and that Starwars dark vador music came on and my hair on my arms raising while that LT1 screamed. I will think of those video's when Im in my death bed!

GM used Hypereutectic pistons for cost(mainly because its a casting not a forging) and the low coefficient of expansion(tighter tolerances). You do not want to abuse these pistons if you don't know exactly what you are doing. Unlike a cast crank these pistons are completely unforgiving.

Agreed. You dont need fancy setup's to hit the 450 mark. ****, I know of several heads and cam LT1 cars that have hit the 450-500 mark several times. I'll even throw a couple of names out for ***** and giggles: Alekks old combo made 500 with a heads/cam setup, I forget his name, but he used to post on cz28.com. It was a red m6 Formula with a 355 that was makeing 480 and running mid 10's.
Here was a fun dyno comparison I'd made for the guys who kept attempting to claim it was a top-end only engine w/ poor low rpm power. They universally agreed a bolt-on stock cam etc. LT1 had great area under the curve at low rpm, so it seemed a fair comparison:

Videos of that setup are in our favorites on our youtube channel here: http://www.youtube.com/AdvancedInduction
As far as the actual goal from the OP - if you have ~5k to spend on full exhaust, fluids, gaskets, tuning, etc. then one of our complete top-end (heads/valve train/gaskets/etc.) options is easily the best value for a reliable 400-430rwhp SAE that you can drive daily.
If you have a couple grand, one of the cam kits, full exhaust, tuning, & n2o will likely be the path. If you have less to play with then nitrous is for you... but keep in mind if you cannot afford to break it, you're flying close to the sun. Were I severely budget limited, I'd address the inlet/exh, and spend the next $ on gearing/converter.

Hah. It is a little shocking to see just how much air an essentially stock displacement short block can move with the OEM head and manifold castings. The difference is so dramatic some of the guys thought I had somehow photoshopped the curves from the bolt on setup. It is a good example of why the guys with super vics, giant heads, etc. are often outrun by OEM castings. The GM castings have more potential than people give them credit for.

You can do it!
I put down 494 RWHP corrected in Nebraska, which is around 535 uncorrected RWHP. Stroked LT1 to 383 with D1SC procharger with twin intercoolers and methanol injection. Price tag 18000.00
