Aluminum block and aluminum heads love compression. I think you will be really happy with your power level but left a lot on the table. To bad E85 is such a hassle finding in Pa. I look forward to seeing some passes at PRP. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

(calculated via wallace @ 0 altitude) Especially important when putting together a pump gas combo is the compression ratio and cam specs. I like your CR choice. What is the duration of that cam? However, even a cam with "too much" duration for the CR will work OK with that much CID. It should be close to your target even with that 0.680" lift cam (.75/1.65*1.5). 574 CID does wonders.

To drop compression that far, the cam must be pretty wild, say 282 intake dur @ .050? Last edited by gregsdart; 04/17/11 08:16 AM. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

Didn't you loan that carb to another member and if so how did it work for them? 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time
