4 Bolt main 455 race block
What are you using to beef up the bottom end of your race big block. I have been using Dave Smiths caps since 1983 Alum caps are on a 482 that is being up dated and the steel caps are going on a new 482 build. Lets see what you guys are using??

Very nice Milan, how fast and what are you running it in? I ran a 497 in the 90s turned it to 7600 no block problems just a crank every 2 years 4.375. It ran 8.50s. building a 482 looking to run the same???

Milan, I found it. Very impressive, It's nice to find someone making that kind of power. Wish we lived closer so we could speak Olds. By the end of the year I will have 1 of my 482s in the car. back in the 90s i ran a 497. had to make almost every
thing!!
thing!!

If it's for a street car it would be ok, when you offset grind a crank the rod journal starts out at 2.500 and when its done it's a 2.200 .300 is a lot to take off a cast crank. i would start with a steel crank if it was me. Also if I was building a 482 for the street I would find a early block 68 F,68 F0,68 F00 bore the block .125 use a stock 4.250 crank = 482.33

No, if you see it in person where the splayed bolts tie in is actually thicker than the pan rail especially after you drill out the pan rail to a larger size bolt hole. Let's face it, none of these Band-Aids are ideal.

It won't be a max effort build but more of a purpose built engine. That purpose is to put a 3400 lb. car under 9.90 E.T. in the heat of the summer, be reliable and run on readily available 112 race fuel. I figure I need to make 725-750 HP to do that so that's the goal.

The engine will be 494 CID (4.25x4.35) with a Bryant crank, GRP rods, Wiseco pistons (13.5:1), Edelbrock heads originally CNC'd by Knowlton (2.19 Int. 1.65 Ex.) and then hand worked some more, a pretty big solid roller cam, Victor intake and a 1050 Dominator built by Milan.

Yes the block needs to be filled due to the splayed bolts entering the water passages. For street use I would recommend an external oil cooler with a 1/2 filled block.
