    Hello again, it seems the more I do, the more questions I have. I'm replacing the cam in the 455 that I picked up a year ago. The original q jet needs a rebuild but I do have a holly 1850-3 600 cfm that I believe wold work as a temporary to break in the cam. I'm nervous about trying to rebuild the q jet, not having it correct, and not starting the engine quickly enough and destroying the cam. Would I need an adapter for the holley to the stock manifold. I plan on eventually putting the rebuilt q jet back on. I was thinking that this would be my best option for a quick start and correct break in. Any advice is extremely appreciated, thanks again, john

    DEADMANSCURVE my first word : truck

    consider a 4 hole holley/qjet adapter also . a few more bucks but supposedly flows a little better . but I guess the 600's not gonna be on there too long anyway .
    there's a small ridge in the middle of the 4-hole from the casting I guess , maybe smooth that down also ? couldn't hurt .
