Maybe you all can help me out on determining this one. I originally purchased the 460BBF from a guy in NY that had the complete lower half machined at a place in NY called SK Speed Shop to include balancing, block work, crank, etc etc. The guy never installed it in his 68 fastback as it was too radical of a build for him and was afraid of twisting the body. Well, I bought it and we had the cam, lifters, and timing replaced. Here are some pictures of when I first started buying engine parts.
Original Engine Purchase
That was the original engine purchase and then we installed new cam, lifters, timing, ported and polished the heads
Now, the new Cam and Lifters - I went top the Comp Cams website and pulled this information from the box
HYDRAULIC − Street/strip, 2800+ stall, 9 .5:1 compression, lower gears, rough idle .Hyd . Hyd . 2300 to 6500 34-250-4 XE284H 284 296 240 246 .584 .588 110°
This one might have come out of the car when it came back from S&K Speed Shop. Not sure where I got this one
All to say, that is what I got and then of course the Mass-Flo EFI system up top. Hoping to make somewhere between 550-600 hp. Any insight/feedback from anyone would be appreciated, thanks
