It's not silly. For once.
Anyone care to look at the difference in curves from the 383 to the 350? How about 50 ft lbs? And it's there most of the way up. That's a ton. I usually don't see LT1's that are 420 ft lbs and 430hp. That's alot of TQ from a crappy intake manifold. Another thing was to keep the HP peak down, that is going limit some things. Namely HP. If we moved the peak up another 500rpm then it would take more budget to do it right (to not lose TQ) but I could get feaseably another 15-25hp. Droping a Solid Roller in this (which is basically a cam and lifter swap in his motor) will get you there easier.
BTW cubes (as in going to 383 from 350) is not going to make HP. You can make the same HP from a 350 as you can a 383 for the most part on a street engine. Mainly due to the fact that you are using the same parts, which will limit you. In racing, yeah you could gain anywhere from 60-80 hp with the whole engine designed around those extra cubes. On the street that's generally much less.
There are a few things I would like to try on Matt's engine in the valvetrain to gain some more power, but the basic setup is not bad at all. What are they? Those 3 things are most likely not going to be found on the forum for a while, but guys could take a good guess at one of them, the next two probably not. BTW it's not changing the cam specs. One hint is that it's applying some LS1 technology to LT1's. Like I said it's only going to get us to about 450rwhp or so.
Trey, your cam in comparison to Matt's is a monster.

Do you mean 15º heads with bigger intake ports???
