Engeing Combo Feedback

[1bad75vette]

Looking to hear what you guys think about this combo. It would be going in my 75 Corvette with factory stall coverter and 308 rear gears. Link http://superchevy.com/tech/0312sc_dm15/ danger mouse test 15 is the one i am looking at.

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 last time I ran a cam close to those specs, I remember that I made a mental note to myself that the car would have been a lot easier to drive with a little looser converter.

thats a NICE combo! i have a 76 vette that i did the same thing to but w/a little hotter mill ! the rear end blew out of the thing.the irs in those things are not designed to handle a grip of hp.
