Where are you guys mounting your horn and what type of horn are you using?
LOL Ron. I thought about cropping the photo for that exact reason, but then thought what the hell, it's a good pic.AZCOWBO said:KC posting that photo of your fantastic motor is a little bit of arrogance!

Block is a 1979 350 4-bolt out of a C-10 chassis, checked for core shift, magna-fluxed, align-honed (crank and cam), parallel-decked, bored .030 over and torque-plate honed. Crank and rods are GMPP (don't know the particulars), Sealed Power dished "blower" pistons, Comp hydraulic roller "blower" cam. All of the above was done by a race motor shop (Sehr Perfromance in Souix Falls, SD).
I built the rest of the motor. Heads are Dart Iron Eagle S/S 76cc, with valves and springs built up by Dart. I changed out the stamped rockers for Comp full rollers (probably overkill for street use, but they're just so damned cool!). The blower set-up is from BDS. Running 1:1 drive for about 6 pounds of boost. Blower is more for the "cool" factor than all-out performance. With the 76cc heads and the dished pistons, I figure I have about 8.5:1 compression, maybe a little less. With 6 pounds of boost, I'm right at the limit for pump gas according to BDS's charts.
Ignition is all MSD... billet mag-pickup distributor, 6AL ignition box (currently with a 5600 chip), Blaster II coil, 8.5 plug wires, NGK plugs. Running about 16* initial, 34* all in by 2800, no vacuum advance.
Carbs are two Edelbrock 600s (p/n 1405) using progressive linkage. I changed out the jets, rods, springs, float needles and seats and changed the pump stroke to maximum, all per Edel's instructions.
Motor has run smoothly and strong from the beginning, but I know I'm running a little rich. I would really like to get the T on a chassis dyno and put a good tune on it. Scott Sehr, the guy who built the short block, estimates I am making around 500 ponies, maybe a little more with a good tune. I know I'm making way more power than I can get to the ground!!
