436 cubic inches. Ported Mopar 598 intake, W8 heads courtesy of Mr. Miller..flow 400+ on the two different benches they've been on. 9.20 R3 block. Molnar 4" crank and gm rods. Kevco aluminum rear sump pan. Compression ended up around 13.5-1 and we'll be running VP C12 fuel. After a long search a usable cam core was finally found at Crane. The grind ended up 264-272 @ .050 .750 lift at the retainer. Pretty stable combo that should provide lots of trouble free runs without a ton of babysitting. All the dyno runs were with a quickfuel 1050 carb, but I'll be running our old 1050 on it from our W5 mill. The combo was not set on "kill"... when I race it's mostly brackets so in all an engine of the magnitude is not necessary..... but it will be FUN and that's what I'm looking forward to! Get it sorted out and I may look at some index racing.
