OK, now I know my block is a genuine 454, and can support additional 0.030 overboring, I'm thinking of building a stroker motor. 4.28" bore, 4.25" stroker crank yields a 489ci engine. /forums/images/graemlins/eek.gif /forums/images/graemlins/grin.gif Connecting rods are stock length 6.135", 3/8 ARP rod bolts, rod ratio winds up at 1.44-1. Compression ratio will be 9.5 using TRW hypereutectic pistons. Heads are oval port "781" castings with 2.06 intake and 1.72 exhaust. Thinking of using Competition Cams extreme 4x4, haven't decided on a grind yet. I saw some good posts on those awhile ago, I'll have to try and find them again. /forums/images/graemlins/tongue.gif Does this sound like a good combination of parts to build a reliable, low rpm torque monster in a daily driver to you? Any recommendations on a cam, (Q-jet and dual plane intake is being used) or changes you would make?
