    We do not know the person you are dealing with like you do. No where close ! As we all know, there are a ton more involved with motor build-ups then the motor itself. Personalities, $$$$$, wants, needs, expectations, half truths, misconceptions, vehicle it's going in.

    It makes it easier for us (internet) to come up with a build since we don't have to deal with all those miscallaneous's.

    When it comes down to general discussions on optimizing things, we can all contribute to that, but not when there are many outside factors going on.

    Build it the best you can with all factors involved and we'll just hope that it all works out for you.

    well that was very positive my friend
    yeah the income deal has become a issue but he is avery good fella to me and my family and like i said i could say hey mark you need hyd roller and single plain intake screw these heads bad idea you just lost alot of money i crap lets go with aluminum heads single plain roller yeah babyhe would say are you sure yeah im sure okayim not gonna do it to him.

    he up in the air over the hyd roller.i figured it up and he would have to give me another 1200 at least to go that route

    thanks cfm and to all who has devoted time,travis

    well fellas im sorry if you feel its a waste of time,the last 496 i built for my ole man cost 12 grand very nice running mill at that.

    i cant help he got fired this afternoon from a job he worked at for 25 years b/c a young foreman under him told his boss he could do his job and my uncles for less money,big fight.oil field guy.
    so things have changed some.his pockets werent as deep as he thought.
    i told him to start with it would be budget built,not full blown bad boy like we did on my ole mans and it really is no bad boy.

    if you have gotten agrevatted with me okay thats fine im on here for ideas.
    there is no need for him to have full forged rotating internals.so i can cut alot down there im mean he may make 550 wit this motor if lucky.he will never use nos and probably only keep this boat for a few more years,
    he wants 20 plus foot pickelfork to begin with.

    he has some money to spare on this thing.i can talk him into a 14-71 blower motor if i wanted.or a 600 plus n/a mill,but i dont want to milk him to death.

    im sure i can say hey mark you need to go hyd roller.give me another grand plus some.then is that grand plus gonna be justified in my mind no.he said he will think about it.

    i should build it put the 292h in there and let it go really b/c he will be happy i wont thats the problem.

    I agree. You and the Uncle need to get some PM work or start mowing lawns on the weekends so you can do it right.

    my uncle has given me free roam on a build,heres what i have
    You should delete that... Your uncle has one of your hands tied behind your back. He should try and understand (you should try and explain) engine internals are a buy once, cry once deal. Do it right the first time, and forget it. The bling can come at any time, little by little, or however. YOu don't build a fancy house on a crappy foundation. The people that you (not you personally) think will be impressed will be laughing behind your back.
    It's easy for us to sit here and spend your money, but if you're really on that kind of a budget, you've almost already wasted more time here than it's going to be worth.
    Just my sometimes never to be humble opinion.

    I built a 460 last year with an ohio crank. I went through the same decision process you are with my oval port heads. I really wish I would have went with a 4.25 stroke regardless of the heads. If you ever want to go to an aftermarket block you will already have the 4.25 crank so you have a good start on a 540. a 496 might only give 20 more hp but will give 50 ft.lbs on torque. Get a 496 crank and i'll trade you for a 454

    i go crazy over this shit hell i am crazy

    i dont know what to do hes just about spent his limit.so far i have spent 2,500 on crap got nothing really.he got another 2,500 to spend tops{hes screwed}or im getting screwed looks like ill make alot f-ker!!

    okay heres where im at budget built 496 with what i have.that will only leave me with about 1,300 at most.
    he wants polished bolts braided hoses ect.
    go hyd.roller hes screwed on the rest.go hyd flat tappet give up 50-75 hp and spend the rest on bling,{if it was mine screw the bling they cant see that when you are wot anyway!!!!!

    im stuck with these heads, the air gap rpm intake is here to stay.
    i can get close to my 10.1 goal and get a good tight squish.
    the bad part is these heads have been set up for a hyd flat tappet that he has already paid for cant get the money outta them new springs they have 140lbs seat pressure kinda stout for flat tappet but oh well.

    any suggestions.i think hes screwed personally

    DD does not take into effect RAM. As we grow in stroke with these engines the RAM effect is increased in the low to mid rpms. RAM is the column of air that continues entering the cylinder even after the piston has reached BDC and is on its way up and as the intake valve is closing.

    As we increase stroke piston speed is increased. As PS increases the intake charge is pulled quicker into the cylinder on the intake stroke. The charge then has velocity and mass. It overcomes the piston coming up and packs more air and fuel into the cylinder.

    This is why you see these low compression stroker engines with good VE%'s.

    from my understanding with building and caming harleys,a late intake valve closing will bleed of compression

    tom do a compression chart kb has one on there website.it will tell you static and dynamic which is corrected after cam timing
