I have a good 454 block with a good steel crank and rods needs bored the shop says .60 will clean it up. how much $$$ do I need to build a high ten second engine? the car will be a 81 malibu all suspesion work is done. is it possible with only 468 cubes?? the engine shop wants to stroke it to 496 and put a roller cam in it with RHS heads the bill will be 8000.00 for a long block, thats a bit out of my price range right now. he said he can cut costs by not stroking it and using a hyd. camshaft. just wanted to see what you more experienced guys think.
