i have a 74" 72 shovelhead, .010 over, i'm going to mill the heads just enough to true them up, and zero deck the stock compression pistons. it's going in a 72 round swingarm frame, not many extras, so it should be fairly light, i will gear the shit out of it ( i like to fly on the interstates) 4 speed with 24/46 sprocket combo, carb is undecided as of now. what would be a cam that would give me a big fat torque curve in the lower to mid range? thanks in advance for any suggestions.
Hey Nate, not to change the subject on you but I'm running a 23/47 setup on my 80 incher and it's a chore sometimes taking off (loaded down with a pack, tent, bullshit).
Hey, I've got an old piece of shit bike I have no clue of it's history way back in '74. I haven't taken the engine down yet, nor did I check the valve guides. I'm just saying, I have no clue how much went into a do the math kind of pile of shit parts all worn out and I am going to stress the shit out of it with a cam.
Now, maybe I did have the bottom end rebuilt, but now I am going to deck the halls and shit. That cam has a higher lift kind of have to be all that fast shit bike kind of now take some deck off and lower that head to the piston kind of I have to change my 10 over pistons to deeper valve pockets or I'm going to bend some worn valves and guides I haven't taken apart and matched that against the book I want cam first.
Before I do anything, I wonder if I had my small end bearings done when I had the pistons bored. I've heard some wild build stories so this asshole is assuming this is and old pile that needs a tone of shit done unless it was a barn find with a few 1000 miles on it. Some shovels should never be touched by humans. Better a monkey would know better. Hope your shovel is better off than mine. Recognize these? Butchered Bikers Breedgay'did he did. Someone shoved my threads all up!
EDIT: i decided to post a couple of videos of my home built and home turbo'd drag car that i built everything on, up to and including the suspension, engine,carb, trans, rear end housing, all of it. i managed to make 2.68 hp/ci from an iron headed 357ci small block, and won three consecutive track championships in heads up competetion, undefeated for one of them, not because i feel like i have anything to prove mind you, but simply because i'm quite proud of the things i build, and have built.

viva la turbonate !!!
thanks for finally answering that nitwit like he should be , that jerkoff hijacks too many threads with his jibberish nonsence , and the one time in a hundred that he does make a valid point is lost on us skipping over his posts has become a too regular task
as far as cam i've used quite a few andrews a , ab , and bh cams with great success in motors for customers
I suggest you run stock for your street riding list. I see no other way out is a grunt bike all well tuned stock. And I have no clue why you are picking on me when I do not post like others. Once you see that big dig swinger singer come flying in, skip over me.
I have a few guys that like reading my shit. Let me ask you a question... Answer me with all that mechanical crap behind you and all that rez you may show your shit and I can't show mine? You sound like the wife with a laundry list I need to follow.
Follow this. I ported my head, run a better flowing air cleaner, polished my venturi and throttle plate all glass finish. How much more flow into the engine do you think I made and you want a cam without that work first?
Say yes or no so we make this real simple to follow. Will porting throw in more air if I buy some mild cam to do the same thing. So, yes or no, more air if I port or more air if I cam up and now say a simple yes or no read it carefully.
furthermore, you are a fool if you did a glass smooth polish job on your ports, you want a surface with some sanding scratches on it. ever hear of a boundary layer? i have, the guy who taught me to port heads taught me about it, he learned about it when he worked for kenny bernstien.
go fuck up other people's threads, i'm legitimately looking for advice here from guys that ride shovelheads, and have real world experience with which cams do what..
You keep on bragging about your shit and can you work a few degrees only say? So is not a stock cam and any other lobe lift is just that. You can have so much lift for race or performance so are we back again to some sort of open and close degrees we are stuck with?
Boundary layer this for me... With all that porting and cam work did we shove more air in the chamber when all is said and done is all I am asking.
just so you know, i am doing a bit of head work, nothing major though, just a little pocket work, 30 degree back cut on the valves, and moving the valve seats a bit closer to the edge of the valves, and profiling the valve guides. none of which will affect my camshaft selection. now please get the fuck off of this thread so i can get real world advice from guys that ride shovels instead of the bunch of jibberish that we are now being subjected to since they obviously now have internet in the special needs classroom.
I asked if your 5-angle valve job will push more air into the chamber along with the porting... Simply say yes or no. It's that simple a concept.
now, how about those isle of man credentials? yes or no.
When I say "DO NOT RESUSCITATE" on my leathers... You are going to have to win it real bad from me is take you out is watch the fuck out you come get some, hear!
I said I never went but was in practice for it. One more time... Are you throwing more air into the chamber as you port and cut the valve circle closer to the chamber kind of moves yes or no?
I think I need to restate a statement. I never said your bike. I was talking about how sad off the bike in the photo was. It WAS a mess. It now is going to be one sweet runner I hope. So, that post was my build I was talking about, not yours. How could I know what kind of condition yours was in but make a fool of myself and assume.
What I did was talk about the condition of this bike, not yours, guy. You have to remember something... http://www.youtube.com/watch?v=OUh2rw9o2JY
I do not come here to fuck around. I can backup any shit you want I say. I say this. One more time... With all the porting, polishing, wall sticking kind of finish, we are sending more are into the cylinder chamber for more HP... Say yes or no because this is about as black and white as I have been posting you see I cannot get even a simple yes or no.... Which is it?
why are you so bent on derailing this thread? port work WILL NOT affect my camshaft selection given the fact that i will not be doing a shit job. i am looking for cam advice, not your ill informed idea of how to make an engine run good, i don't need any advice on how to make them run good, i've already made more hp/ci than you ever will, so you're going to have to forgive me for thinking any of your ideas are simply wiki'd internet bullshit. now, go study on how to do a proprer port job and get back with me in a couple of years when maybe you can pick up what i'm putting down. unless you can tell me which cam i should be using based on your own real world experience, your input is no longer ( and never was for that matter) needed or welcome on this thread.
