My 318 is a stock bottom end from a mid to late 70's car. (cast crank, rods, pistons.) Its got keith black silvolite cast pistons that are .060 overbore, with 4 valve reliefs and they are .070 down in the hole...(remember late 70's low compression)
I did a rering job, honed the cylinders, emory clothed the crank journals and installed new main, rod, and cam bearings. Assembled the short block with a comp cams double roller timing chain, a timing chain tensioner from a magnum engine, and the MP windage tray kit, with a HV oil pump.
The cam & lifters I used is an Edelbrock Performer RPM kit. 234/244 @ .050 and 488/510 lift and a 112* LSA.
For the heads, they are the RHS/Indy X heads prepped by Brian @ IMM with 202/160 valves, 5/16 stems, and beehive springs for a lightweight valvetrain combo. They have a 62cc closed chamber.
I used Hughes Engines 1.5 roller rockers, and custom length comp cams chromoly pushrods.
The intake is an Edelbrock Performer RPM with a holley 650 spreadbore carb. It is, IMO, a very responsive carburetor.
To finish it off, I used TTI headers.
This engine is in my '68 Barracuda fastback, with an 8 3/4 and 3:55 suregrip. Rebuilt 904, red clutches, kolene steels, 4.2 lever, HD band strut, HD accumulator spring, with a TransGo II shift kit. 3000 stall PTC converter.
I haven't been to the track so I don't know what it runs or what I have for horsepower... 310 HP maybe??
