Off the top of my head? 30 over 318 with KB167 pistons. 273/2-bbl solid cam. 302 casting heads with stock valve diameters and the sharp edges smoothed off. Factory 4bbl intake with TQ, IIRC, and TTI headers because the next plan is a 400+ inch SB. Best numbers he's posted so far if memory serves are 23 city and 29 HWY...maybe 23 combination city/hwy, and 29 hwy...
