A few questions regarding an engine I'm building. I'm just gathering parts for it right now, and I want to get some input as to what will work and as to what won't work. I'm getting information for several sources so I figured I would come here to put another source on the notch. Can't have enough info, right?
I'm building a 393, and keeping N/A for now since I don't have the means to purchase a blower right now. I want it to have around 9.5 c/r, but I can't really pick out the pistons yet since I need to have a combustion chamber size first. I want the blower to push out around 9psi tops. I really haven't look at it in terms of "I want this much power so what build do I need," but rather in terms of "I want this build so how much power will I get."
It's coming time to decide which heads and cam to get. I want to buy one set of heads and be done with it. I intend for this engine to be a 393 with a blower so I was looking into AFR 225s. Will this be too much of a head for a N/A 393? Would something smaller like a 205 be more ideal? I really don't plan for the engine to exceed 6500 rpms since it's a street car. If all else fails, I have the stock heads that may or may not be cleaned up. Their condition is quite questionable.
As far as the cam goes, I don't want anything more than a .600 lift. I want a cam for the N/A 393 since it won't cost an arm and a leg to replace like the heads would be. I want the curve to remain very similar to the stock curve but allow more breathing, of course. I haven't done much research on cams yet so I'm clueless as to what would be available as good options.
Perhaps this is a half-baked plan for an engine build, but I came here looking for guidance and answers.
Also, I saw someone on here with a sheet-metal box intake on their 351, and they said it easily cleared an R hood. I would like to get some more info on that because I really don't want to get another hood to clear the giant intakes.
