We finally found a 390 with enough meat to bore to 4.100 comforably, added Diamond pistons and SCAT rods. Reworked the heads and balanced the rotating assembly. All in all I came out around $7000 when it was all said and done. Actual displacement is about 418 cuIn. HP runs right at 485. Plenty for street use.

I think that's a really smart way to build a car now. With 427/428 blocks getting harder to find, putting in a meaty 390 is so much better than a SBF and way better priced than a Roush. If I were building one today, that's probably what I'd do.
