    Congrats. What will you be doing to the motor? Mine looked a bit worse than that when I started - lots of elbow grease later and she turned out real nice.

    right now I'm just going to take it apart to see what needs to be done, I want to balance the bottom end, new cam...of course. I've thought about stroking it out, but we'll have to see what the budget says. I was looking at the 496 kits /forums/images/graemlins/peace.gif
    I do have a question for y'all though.
    What cam would you suggest???
    I haven't descided....but I was looking at comp 4x4 extreme
    I think crane also has a truck cam....
    What do ya'll think, help me build this motor /forums/images/graemlins/thumb.gif

    I went with the Crane Energizer 266 for my 454. I had a pretty knowledgeable guy help me figure out what was best and this was his recommendation for gobs of low end torque. I then called Crane and they made the same recommendation.

    The guy who helped me pick this came said the Truck cam was also a good choice but not really worth the price difference.

    I went with that cam, along with Crane springs & retainers, and Comp Cams roller rockers. What will you be doing for fuel delivery? I went with the Jet Stage II Quadrajet, again on the recommendation of my friend. He has had great luck with them. Fuel injection was outside of my budget.

    wellll...I'm finally taking it off to the machine shop tomorrow AM. The cylinder walls look real good. The only real big thing I'm gunna do is put big valves in the heads. I'm going with the 2.19/1.88's. I haven't descided on a cam, but I think I'll give Crane a call like Yukon Jack did. I'm going to replace the all the bearings, rings, the valve springs, and the rocker arms. I'm hoping to be able to hone out the cylinders. I can't wait until I can fire this thing up!!!!!

    I'll try to keep y'all posted

    I'm reading some good stuff on Comp Cams Beehive shaped springs. On a pretty wild build they picked up 30 hp using them, that is substantial from just valve springs.

    Glad all is looking good so far.

    I have a print out...here it is...
    Comp Cam Grind number CB X4 254H-11
    part # 11-231-3
    Duration @ .05 intake= 210 exhaust= 218
    Lobe lift = .297
    Lobe sepration = 111

    CompCams recomended this grind to go with my 454 using the Edelbrock MPFI intake and a 9.5:1 compression ratio, built for lowend torque. Basic BBC stump puller /forums/images/graemlins/woot.gif

    Hope this helps, I am no gearhead so I relied on my engine guy to work with CompCams to figure out what cam would be best for my build up /forums/images/graemlins/waytogo.gif

    The bigger valves will probably hurt your bottom end a little bit, but that's what gears are for.
