Re: 224 cam owners: peak power @what RPM's? Here's a dyno pull of my Formula from last week. TR224 (114 lsa), longtubes, ugly restrictive custom y-pipe, 3" exhaust, lid, ported maf, ls1edit, free mods.
373.4rwhp/366.4rwtq

I do love this cam! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> You can see it peaks a shade below 6k, and keeps rockin til the 6800rpm rev limiter.
Hopefully an ls6 intake and decent y-pipe/exhaust will put me over 400rwhp with stock heads...
Later,
Drew

Mine peaked at 389 hp at 6000 rpm,s. and 382 tq at 4200 rpms. I wonder what made our peak rpms so differant unless the advance came out differant.Or the fact that I have Mac headers and do you have long tubes? I have to say this cam pulls like a **** all the way to 6800 rpms My dyno graph is straight across fromm 6000 to 6700 and just starts to go down at 6800 rpms when the dyno shuts off. I think my hp has gone a goo bit higher since the moter has broken in as the dino was done with 1000 miles on the new engine.
