454 supercharged Build
Here is the deal. I've got a 454 block and crank, and I wanna build a 550-650+ supercharged engine. I know there are alot of threads on 454s but I haven't seen any on supercharging. Maybe im looking in the wrong place. AnywAy, here is what I'm thinking:
1, Stock block 2. H beam rods 3. Forged crank 4. 8-71 blower 5. Roller Cam/ lifters (size needed) 6. Aluminum Heads (size needed) 7. Superchiller (optional. Do I need?) 8) 9:1 on piston ratio. Your thoughts and comments are needed to help put the right combination together. |
Im partial to AFR heads. They are generally the best flowing head out there out of the box.
Have the camshaft custom ground by somebody who knows what they are doing, you want something with a wide lobe separation around ~114* if you can get the superchiller its going to help a lot with keeping temps down since these blowers really put out the heat. compression ratio is good steel crank & h beams are good the factory forged cranks are not as strong as the some of the aftermarket ones you can buy today due to a different forging process which makes them stronger |

Bob can set you up with a matched cam and heads to meet your goals.

HEad Selection
Looking at AFR HEads. 335CC ? Calling them up today to figure out the right selection.

why 9 to 1 SCR? If you're gonna run a blower, drop it to 8.2 to 8.4 and let the blower do the work.
