My 331 Round 2

It's a T5, stickshift. The cam is a 220/224 .490/.490 109 LS. I'll scan the curve tomorrow and post it. Basically, we leaned out the carb two jet sizes on the primaries, and three on the secondaries, increased the squirter from 31 cc to 32 cc, and changed the secondary spring to the purple spring. Timing curve is the stock MSD curve, with initial timing at around 13, total at 34. I say around because I had to hack off the factory timing pointer to make room for the new water pump with driver side outlet, so I'm not exactly sure what the timing is, but I know how to get it back to this setting. Oh yeah, my air cleaner is holding me back, and they suggested I upgrade from a 2.5" K&N to a bigger one and possibly an X-tream air filter lid as well. My other dyno post was achieved with the aircleaner off, this peak is with it on. Earlier in the dyno session yesterday, did two pulls changing nothing except removing the aircleaner, and it was good for about 12 hp.
