OK here's my question. How can I use a 5.7" sbc chevy rod in a 2.3 motor? I know I will need to use a small journal rod, but the ford rod is 1" inch wide and the chevy rod is .950 wide. Would it just as easy to use a ford rod? This will be a turbocharged motor for a drag car, it will see 20+ lbs of boost and shift atleast 7200 rpm, with a C4, 3.55 gears in a 2900lbs car(maybe lighter). Any advice you can give me will be great.

Thanks Jeremy

Everybody uses chevy 6 cylinder rods . You can get the crank machined for this.Or an aftermarket rod will work without machining.

I wouldn't trust stock chevy rods in it.

I think the small journal chevy rod is wider than the stock ford rod? When you use the 250 six cylinder rod you need to widen the crank journal and turn to a 2" pin.

the chevy rod is wider. the crank must be machined. the chevy rod is a weak link. i ran them for 2 seasons in my dirt car with some trouble. racer walsh has a real good crower rod that i will be running next year at a good price. plus they are lighter. i wouldnt use the chevy rods on a turbo motor.go with crower rods, kb pistons and a good steel crank. or use a 2.5 stroker kit for some real power. good luck.

the big E.,does have good equipment,but it ain't cheap.Racer Walsh has decent equipment,but it is usually stock type parts,more reasonally priced.Johnson machine is as good as big E and they ain't cheap either.good parts =reliability! as Dr.D.Berggren from Speedway Illustrated has said for years,speed costs,how fat is your wallett.or the best way to make a small fortune in racing,you have to start out with a large fortune! racing is the fastest way in the world to turn MONEY into NOISE!

we dynoed our motor with 3 different intakes,a stock one,an Offy,and a fuel injection intake that was ported and slicked up,the best results came from the fi~intake.we also tried 2 different carbs,a 350 holley{carb shop} and the tried & true 4412 which showed the best results.our head is D~port cut.175port &polished,we run a solid lifter set~up.the dirt track we race on has no cam rule,but the asphalt track we race at don't allow rollers,stock or after market.we have run this motor on both the dirt & asphalt track.
