i'm getting ready to assemble mine next month
its the generic 1988 330 hp 454 ,
heads are getting tossed for 049 large oval gm heads , stock valve size, fresh out the machine shop ($385.00)
intake is a 454-0 hi rise single plane ($125.00)
750 holley dual feed single pumper that is marine ($125.00)
i really stole the exhaust , older set of rewarder headers , not water injected , but real water jacketed style , headers / risers and bravo 1 tail pipes with the water exiting at the end of the exhaust tip ($500.00)
set of hp500 valve covers ($150.00)
another 200 bucks for all the gaskets and misc junk
i hope to see 70-80 hp , and running the same 4800 r's
that my old motor put out ,
after i get a baseline with my mirage plus 23 pitch i'll start shopping for a prop to compliment the power
