I have a 92 Z28 with a stock rear end, stock 700r4 transmission, and im building a 406 sbc to put in it. It has a zz409 hydrolic roller tpis cam, summit brand vortec heads, forged pistons,5.7" rods, TPIS big mouth intake, SLP intake runners 24 lb. injectors, holley 58 mm throtle body, Comp Cam 1.5 roller rockers, hydrolic roller lifters. just lookin for some input on what people think i can get out of this motor on the track and the dyno. Any advice or sugestions would be apriciated also.

 

Which TPIS cam? There is no ZZ409 that I know of, unless I'm forgetting something? Did you mean the ZZ9? If so, that's a small cam for a 406. One local member built a 406 with a Comp XFI280HR-113 camshaft, and made 403 RWHP with a SuperRam intake.
