I install a comp cams 270h cam in my truck today.

I have the motor at TDC on the intake stroke.The dots on the timing gears are lines up.The thing is the 1st lifter on the driver side.Is up a little bit.Just a tiny bit.

Is something wrong.I thought that both lifter's should be all the way down.

Any thoughts?

 

If one of the lifters is up when the timing marks are lined up, it normally means that #6 is at TDC, and you need to turn the crank one full revolution to get #1 to TDC.

I think.

 

Yes.

When both "dots" are at 12 o'clock is when #1 is firing.

 

Well that makes since.When I installed the cam both where down.Then I rotated to make sure everything was alright.And my mom started screaming at me for taking my truck apart again.(I have a tendancy to do that)So I quit paying attention.

Now I am waiting for my intake and carb.Hopefully those little 4 cylinders wont be a problem!

 

Your fine, and installed the chain correctly. The instructions have you line it up dot to dot, cause it's easier.
Like 'si_camaro' said your crank & cam are at #6 TDC. Something the instruction fail to mension some times.
Techniclly both dots are at the 12 O'clock postion to be at #1 TDC.

BTW: I also install my chain dot to dot. It's easier & you don't need a straight edge.

Well that is good news.

I just looked up the casting # from the heads.They got 1.72 and 1.50 exhaust valves.Casting # 3927185.Well dangit.Are 882's any better than this.My cousin has some that I might be able to get ahold of.


I am still hoping for good results.Cam,intake,carb swap all at once.next on the list is headers.Then I guess heads.

 

882's have huge 76cc chambers but bigger valves, while the 185's have 70cc chambers and tiny valves. Your call they are both crap.

 

Yeah I figured that.


After headers maybe I can save up some dough over the summer.And get some protoplines.

 

i had a set of heads from a 78 350 with 1.72 intake valves

threw them right in the trash where they belong
