namz7791 Posted June 3, 2004 Share Posted June 3, 2004 Took my 88 355 sbc to the dyno yesterday and hit 305 hp and 356 ft-lbs torque. Engine is runnig 9.3:1 compression with flat tops and the 65 cc heads that came with the TBI engine that I rebuilt. I am using the Comp cams 270H grind with the performance products Cyclone intake (edelbrock performer RPM air gap clone). Heads had a 3 angle valve job but no porting or such. Dyno guy didn't think that we would hit 300 because of the heads but I guess it is fairly easy to get a smallblock to the 300 hp range. Good set of heads and 1.6 ratio roller rockers are coming next year so should get close to 350 hp. Interesting side note is that I am running an Edelbrock Performer carb 650 cfm and the dyno guy swore up and down that a Holley would really add to the engine so he stuck on a holley 650cfm double pumper. He gained 6 hp and lost a little torque so I guess a properly tuned carb is what is important not the brand! Well I hopefully will get it in this weekend . Wish me luck!
