Re: 540ci BBC build
I love my 505. It made 668hp on the machine shop dyno on 93 octane. You can go 6.50's no problem with a 496 or 489 kit. Paul69 is running 6.50's with a 489 that was having major issue's. He is now bumping it up to a 496. You can make major power without a aftermarket block, but if you have to have 540+ cubes than a would get a 427 tall deck. I have seen them on Craigslist here in houston for 100.00. Cam and heads make more of a difference than cubic inches.
