...I picked up 20rwhp over baseline for a grand total of 340 with a setup not too far off from what I run now... Naturally aspirated, of course, then factor in the 200 shot and changes made after the dyno pull (and the times I run...) which puts me somewhere in the neighborhood of 550+ @ 3100lbs. w/ driver.
Sorry for butting in on the conversation, but I'm subscribed to the thread and have been reading along... thought you might wanna know anyhow.
Good Luck with your combo's guys... I wanted to build a 331 this winter. All I have at the moment is an R block... so I'm prolly gonna transplant the 306 rotating assem from the stock block over to the R block and add some more spray, shoot for some 10.0's or 9.90's next spring.
Take care
