hi guys,

so i just got my bisimoto 3.6 camshaft and my supertech valves and the cam card says the following:

-check valve to valve clearance. it may be necessary to remove material from the valves or sink the valve seat hight to the head,

-check the valve spring retiner to valve guide clearance at max lift. remove material from top of valve guide to provide a minimum of .030" clearance.

did anyone ever had to do this on their engine? or is it just a "check to be sure card" ?

i'm a little worried because the next section says this:

-be certain that cam and or rocker arm rotate freely in head or block :S block? really?


ne1?

thanks

 

maybe he meant the entire rotating assembly since if some or part of the valve train binds, neither the head or block will rotate freely.

 

its the most bad *** cam you can buy for the motor. you expected it to drop in like an OEM cam?


make sure to check everywhere it says to check. unless you dont really care what happens.

 

Check and recheck. Check the valve guide seal to retainer too. Remember to check the installed height as well. Everything is pretty tight on big cams and .010 off can really tear some **** up.

 

sure, i will check everything,i assumed i will only need to notch the head like with the crower cam,

i didnt think that the valves could hit each other, do you guys have the 3.6? did you had to sink the valves in deeper or remove any material from your valves?

i didnt imagined that the retiner could hit the guide\seal.

ps, how do you guys lock vtec?

thanks

 

Hello RACEPACK thank-you very much for your purchase of the Bisimoto Level 3.6 camshaft you will be more than satisfied with the power it will help deliver with your turbo setup!

Being this is a Bisimoto's race camshaft everything on the cam-card is a must to double and even triple check due to the very large lift and duration. This is normal procedure for any proper engine building. Be sure to properly degree camshaft as well.

 

Oh yeah. With the head off you deff need to check your V2V. Build yourself a spreadsheet so you know what's safe while tuning. Once you do that, set the head on the block and check your P2V clearances. You'll want .030-.040 in clearances there too. Especially for a high revving engine.... even more if running AL rods.

 

Did I miss something? I didn't see what engine this is for. If its DOHC you can solve most v2v issues with dialing the cams apart. Keeper-2-seal clearance is usually ok, but make sure that lift doesn't put your springs into coil bind.

 

stupid q, but what is coil bind?

i had to make some room for the cam to have enough clearance in the head,

now it seems i need to cut the end of the rocker arms since they touch the opposit side rocker arms,

i wanted to know how the rocker peds are installed on the rocker arms? glue? :S ? induction welded?

will it be safe to grind using a belt sander? is there a chance that the heat will destroy the rocker arms? or will lossen the peds?


this is what i'v done so far,

 

upupup

 

My cam has room in the head. I'm still in the process of my build too. I'll get u some detailed pics soon

 

sweet, which valves are you going to use?

 

I'm using stock valves. Supertech springs/retainers. Head has serious port work though

 

stock valves with a 3.6???? na?

 

definitely not..... what are u trying to accomplish by using aftermarket valves? just curious

 

We just drop it in and go.

 

OEM valves should be the last thing you worry about. Sorry to say, OEM valve is better then a lot of aftermarket valves.

 

Coil bind is when the spring is compressed to the point that the coils touch and the spring is basically solid.

so how do u change v2v on a SOHC since advancing or retarding cam will move both exhaust and intake valves so v2v will always be the same...

 

nothing actualy, i got a deal for a new set of supertech valves for $100 shipped.

 

The lobe separation is high on this cam. Valve to valve will be ok unless using larger valves, then I would check it before running the cam. Degree the cam in and call it a day. The point of degreein' a SOHC is to make sure intake or exhaust center line is not out of wack compared to the other. You should have a timing card saying what centerline the int/exh lobes should be at. Good luck...

 

their point is, since this is the baddest single cam turbo cam there is, people might be going with over sized valves.

if they go too big, on either intake or exhaust, theres a chance of v2v.

 

this is what i had to cut from the tocker arms to make it work...

wierd that most of you says it was just a drop in.

 

wow. do any of the less agressive cams (ie 2.4 or 3.0) need this as well? and does anyone have a good vid of one of these cams at idle
