Cool dude
Got my 340 on the dyno.
It's a 70 block, forged crank, balanced, line honed, ARP rod bolts, slightly used heavy old TRW forged pistons. Calculated out to 9.7 to 1. J heads I ported a little. 2.02, 1.60 valves. Clay Smith 292 240 @ .050 .472 lift on a 108 lsa installed at 106 solid flat tappet single pattern "Chevy grind" according to the know-it-alls on here. 1.5 Mancini roller rockers. LD340 intake and a 750 double pumper and a 1 inch tapered 4 hole spacer. Dyno guy had 1 3/4 headers, although I'd rather have used 1 5/8.
Stock recurved electronic distributor. Nothing exotic. The rockers were by far the most expensive parts.
Best of 395 hp at 6300 and 377 tq at 4900. Runs very smooth and pulls past 6k with ease.
I was hoping for close to 400 hp so I'm happy with it.
