Vortec Numbers
Its that time the time to start getting my parts for my top end of the motor to try to fix what bubba built me. I am looking for those who run vortec heads. What are your hp/tq numbers and what setup do you have or what is a good set up. I am buying the sdpc upgraded vortec head to accept .550 lift. So any info is appricated. I am looking to get about 400hp/tq thanks

THE BEST BUILD
Through all this we've learned that there are certain ways to build an engine to give you the best power-per-dollar. And the best thing is that all the combinations we've tried so far would be easy for you to duplicate yourself. Perhaps the best combination for the money we've tested has to be the Vortec iron heads and COMP Cams XE262 camshaft with an Edelbrock Performer RPM Air Gap intake we ran in DM Part 6 (February 2003). This engine made tons of low-end torque and still managed over 415 hp--and all from a very affordable and streetable package that even makes enough vacuum for power brakes.
T15--DM Part 6: GM Vortec iron heads SDPC PN SD8060A (64cc chambers, 170cc intake runner volume, 1.94/1.50 valves) with Comp Cams 1.6:1 Magnum roller tip rockers PN 1418-16, Edelbrock Performer RPM Air Gap Vortec intake manifold PN 7516 COMP Cams XE262H cam (262/270 advance duration, 218/224 duration at .050, .462/.469 valve lift, 110 lobe separation) straight up.

The Vortec heads we tested have been the best bang for the bucks of anything we've tried so far. The TFS aluminum heads are a close second to these iron units.
