During the last year I've built three 318's that I took to dyno. Nothing special, or at least special in a sensible way, but real world build ups with low budget and probably medicore results.
1) A 1980 318. New bearings and rings, hone job. Double roller timing chain. Stock heads with stock valves, milled .040" and homeported. Comp Cams 260 HE cam, factory distributor with quick and short advance, performer intake, 1850 Holley and shorty headers with 3" exhaust and mufflers. 265 hp between 4500-5000 rpm.

2) a '73 318, .030 oversize, KB hupereutectic pistons,302 heads with 1.88" intake valve, homeported. Cam was a comp cams XE275HL and the intake an old Offenhauser 2 x 4 with twin 400 cfm carters. Distributor unknown electric, same shorty headers and exhaust as in 1). 335 hp at 5500 and still raising, the owner didn't want to wind it higher. Might have produced a few more.

3) a '71 318. '030" overbore, old TRW dome pistons with the dome shaved a lot, just over 10:1 cr. polished 360 rods with ARP bolts. mid 70's 360 heads with 2.02/1.60 valves, homeported. Lunati Voodoo 30200741 solid cam, 273 pushrods and rockers. Torker 2 intake, 1850 Holley, 1 5/8" cheapo headers, 3" exhaust with mufflers, MSD pro billet distributor. 391 hp at 6000.
