I don’t want to build anything to radical and I don’t plan on building a 1000hp motor but I don’t want to drive around with a worthless blower either. I have never built a blower motor before but I was told this 400 had a blower on it at one time. Does anyone have any suggestions or know how much I should expect to spend?
The 400 sbc is about the last engine I would ever put a blower on.
With their thin walls and siamesed cylinder's this would really make me nervous.
If you are "hell -bent" on this I would "o'ring the block and also have it sonic tested.
If it is a two- bolt block I would also run "splayed" 4-bolt caps.
If you have a good 350 block I would just build a 383
With the thicker cylinder walls you have a much better chance of keeping gaskets.
