I may be expecting too much from my 340. It isn't slow but still just doesn't seem as strong as I thought it would be. I have tuned and re-tuned down to about as good as I think I am able.

Here's what I have:

1969 340 block, bored .030
Speedpro Forged pistons
Scat rods
Scat crank, everything internally balanced.
Lunati Voodoo 60402 cam
Edelbrock 60179 heads with ductile adjustable rockers
Edelbrock RPM performer intake
Holley 750 vac. secondary
MP billet mech advance distributor, curved at 22 initial 38 all in.
Doug's Headers with 2 1/2 dual x pipe exhaust.
904 transmission with low low gear set and Cheetah auto / manual valve body and Hughes 2500 rpm stall TC.
3:23 Sure Grip rear
255-60-15 tires in the rear.

The car will get up and go but it doesn't roast the tires like I thought it would. Matter of fact I can't get much of a burnout using the brake. Again, maybe I am expecting too much out the 340. I guess i had my hopes up for more. I'm a bit disappointed.

Am I expecting too much? Have I done something wrong with this build?
