1G Big rod? Options

[BudmannG]

Is there a way to tell the difference between the 1G big rod and one that is not? Are there markings or something on them?

Here's some very insightful information about the combo copied and pasted from DSMTuners.com:

In the conversation I noted above, the gentleman said the following about his buildup (VPC, 18G, FMIC, 660s)... he said his Extrude Honed intake gave him 35HP on TurboTrix Dyno, his 272 cams gave him 25HP on TurboTrix dyno, the 2G pistons gave him zero HP on TurboTrix Dyno but cost about as much as the other mods. He also started going thru headgaskets pretty regularly (higher compression = more succeptable to knock). Granted he did not have a means to control timing, which with the 1Gs can be pretty radical after 5.5K RPMs (big spike at 6K).

I don't dispute that higher compression pistons will help power production if have control over timing/fuel and properly tuned for it. But for the person whom looks to do this swap as a mod to perfectly fine 1G engine, I still say money is best spent elsewhere.

Also spending the money for parts (rings, HG) / machine work (machining rods, honing of bore..bla..bla..bla) to stick in used cast pistons is a bad idea all around. Forged pistons that fit the 1G rods can be had for ~$400 (I'm sure even cheeper) and will stand up to misjudgements in tuning much better-er



Overall, there's no real advantage to them that substantiates spending the money for machine work and new pistons. Keep your stock 1G pistons or go forged.
