Has anyone out there used the holley Systemax Engine kites from summit? If so does it perform well and is it worth the money? the kit includes upper and lower intakes, holley 61cc aluminum heads, specialty designed roller camshaft with 221/223 duration@ 0.50 509/509in lift with 107 degree lobe seperation hardened pushrods and a double roler timing chain. it says it will give 350 horses. heads have 1.90 1.60 valves 165cc intake runner here is a link to the page .http://store.summitracing.com/partde...p;autoview=sku please let me know what you think of this combo i am considering buying it

holley is a good brand but the only thing worth buying is the intake. the heads arent nearly as good as afr's or trickflow's. and the cam is a very very mild one. you wont get 350 horses out of it. buy the holley intake, tf or afr heads, and get a nice comp or custom cam.
with the bolt ons u can get to 300whp.
