===355 SBC street motor, budget build=== *Block: '68-'86 Chevy 350 Gen I bored +0.030". Check main bearing bore for round and parallel, align hone or align bore as necessary to correct the bores and insure they are ''round''. Once the main bores are done, register the block from the main saddle and cut the block decks to square the block up and set the squish where you want it. Don't try to cut corners here, this lays the foundation for the work and parts to come. *Crank is the stock 350, 3.48" stroke, 2.450" main journal diameter. *[http://www.competitionproducts.com/Custom-Rebuilt-GM-Rod-Chev-350-LJ/productinfo/804335/ Rebuilt rods] are sufficient for this build. If using an existing set of stock rods, ARP hardware and resizing is recommended. **Scat makes a decent set of [http://www.summitracing.com/parts/SCA-25700P/ 5.7" forged rods] that are affordable. *Pistons: [http://www.kb-silvolite.com/kb_car/performance.php?action=details&P_id=155 Keith Black hypereutectic], p/n KB193, 12cc D-cup, 5/64,5/64,3/16 rings. 1.561" compression height. Gap top ring 0.026", second ring 0.018". *[http://www.competitionproducts.com/RHS-ProTorker-Vortec-Cast-Iron-Head-170cc_64cc-Bare-Each/productinfo/RHS12410/ RHS Pro Torquer Vortec] heads, p/n 12410, 2.02" intake, 1.60" exhaust. These heads will accept either conventional or Vortec type intake manifolds, they are drilled and tapped for both types. More on using an early style intake on a Vortec style head can be seen [http://www.crankshaftcoalition.com/wiki/Intake_manifold#Using_an_early_style_intake_on_an_aftermarket_Vortec-type_head '''here''']. *Intake manifold: Dual plane, highrise such as the Edelbrock RPM p/n 7101, Weiand Stealth p/n 8016, Holley p/n 300-36 or Professional Products Typhoon. Check ebay and craigslist for used manifolds if your budget is tight. *Carburetor: Vacuum secondaries 750 CFM. *Headers: 1-5/8" primaries, long-tube. Install "X" pipe between collectors and mufflers. Run 2-1/2" pipe to the rear through mufflers of your choice. *Camshaft: [http://www.compcams.com/Cam_Specs/CamDetails.aspx?csid=72&sb=0 Comp Cams 260H] flat tappet hydraulic, installed straight up. *Rocker Arms: 1.6 ratio on both intake and exhaust. *Static Compression Ratio: 9.6:1 *Dynamic Compression Ratio: 8.4:1 *Quench: 0.035" to 0.045". Zero piston deck height with 0.035" to 0.045" head gasket or 0.010" to 0.020" piston deck height with Victor Reinz p/n 5746 head gasket that compresses to 0.025". ====Results==== :'''RPM HP TQ''' *1000 59 310 *1500 103 361 *2000 150 395 *2500 192 402 *3000 246 431 *3500 306 459 *4000 360 473 *4500 407 475 *5000 442 464 *5500 453 433 *6000 450 394 Stock converter and stock rear gear will work, but would be more fun with a converter that stalls at 2000 to 2200 rpm and a 3.73 rear gear.
