You should be fine to use the valvetrain you got now, unless you're going with some crazy regrind.

 

Don't know the profile yet.. but we decided to max the regrined to what's possible with hydraulic lifters and lash caps!

 

That will be determined by a fancy computer. For a rule of thumb: if you start getting valve float, you went too big on the cam.

 

Yeah, luckily i'm not the one that does the calculations : )

 

So, they have decided what profile to grind now.. It will be



275 degrees duration

10.1mm lift

 

You will be glad to run the Megasquirt with a profile like that. The stock computer might run the engine, barely. Might.

 

Just put the cams back into the engine, with lash caps.. and, it does not start, sounds like it doesn't want to at all! Wihu.. Time to go MS

 

! Check the timing and make sure all the sensors are in right. If it still won't even try, I vote for giving the stock cams a chance, just to make sure that is the only reason it won't run. Check the position of the little nub that actuates the cam sensor also.

 

Timing is correct.. all sesors should be okey also.



It makes (sounds like the engine turning faster) some attempt of egnite the mixture occasionally.. but thats all. After a while, fuel steam starts comming out of the air filter.. so mixture and injection timing is probably way off for these cams. Probably just a bit to much to handle for the original ecu.

 

It's alive!
