TCSS1970 Jan 28th, 09, 10:19 AM I'm fixing to order a stroker kit in the next few days. Mild 489 with stock 781 heads, 60204 cam, 800 cfm holley double pumper, holley strip dominator intake, M-21 trans with a 4.10 rear gear. My question is for a lot of street driving shoudl I get the pistions 10.1 compression or 9.0 compression? Its just a matter of what kit I select. Only see the strip occasionaly. Only want to run pump gas. Which ones, 10's or 9's? Dave427 Jan 28th, 09, 10:25 AM 9:1 with your iron heads, this engine will make great torque. Dave SS402 Jan 28th, 09, 10:26 AM It's all in the way you design the engine, 10:1 static is fine if you optimize the dynamic compression and pay attention to the quench.... Tom Mobley Jan 28th, 09, 11:22 AM 9 if you want to drive it on a pump gas with iron heads and a reasonable street cam. cstraub Jan 28th, 09, 11:44 AM The 9 to 1 kit for iron heads and pump gas. Who knows with the new administration we may only have 87 octane in the future. If you need a quote on a kit I'll be more then happy to just send an e-mail or PM. DZAUTO Jan 28th, 09, 11:53 AM I would only say keep it UNDER 10:1. As mentioned, with today's pump gas, going over 10 is real iffy. TCSS1970 Jan 28th, 09, 1:17 PM I was leaning toward to 10's, so thanks guys I'm going to take good advice and go with the 9's.:thumbsup: Tom Mobley Jan 28th, 09, 1:37 PM good decision. see Chris Straubs post above, does anybody think the gas is going to get better? Not likely, I forsee the future and the number 87 is prominent for some reason. SS402 Jan 28th, 09, 1:56 PM if worse comes to worse we can just switch to E85 and never look back wildman926 Jan 29th, 09, 3:26 PM Who knows with the new administration we may only have 87 octane in the future. good decision. see Chris Straubs post above, does anybody think the gas is going to get better?

We need to take back our country, and stop these crooks in Washington steering us towards socialism, taking away our liberties and our freedom!!
