Time for an engine rebuild!
Iím rebuilding my 496. It had rectangular port Chevy heads, mechanical roller cam, Crower crank & rods and Wiseco pistons. I originally built it in about 1988, itís a four bolt 445 block. This motor dynoed at 598hp and 592tq on pump super, it was all over by 5500 RPM. An original Crower lifter, from before they started putting wheel lube holes in them broke. Of course the engine needed to be torn down to get out all the junk. There wasnít much and the filter was clean but I didn't want to chance damaging the crank. It wasnít, itís perfect.
Iím having the custom Bullet cam re-ground for hydraulic lifters, itíll have .650 lift. Heads will be oval port Brodix. Lifters will be Isky needle free bushing lifters.
My machinist, Glenn at B&B Machine in Oceanside N.Y. is running the block through the washer, doing a clean-up hone, installing cam bearings and fitting new rings. A Shumann oil pump, new bearings, timing chain, gaskets-this will be about the 15th engine Iím building. While I was pretty happy with itís power before, Iím told that I should pick up 80hp with the modern heads, Iíll be happy with 50.
How may I help you?
