all i changed was the cam-but i did retard it 4 degrees. i moved the crank snout pulley to the right in the slot for 4 degrees retard. then i lined up the top and bottom gear to be dot to dot. then i put it all back together the way i took the car apart.

You did line up the retarded mark and the camshaft dot?? I'm asking what mark you
lined up to the camshaft? Stock or retarded keyway?? Should be the one for retarded.

Sounds to me like you retarded the crank but not the cam

i lined up the top and bottom gear dot to dot as you would normally. the crank snout gear keyway is in the slot for 4 degrees retard, its not lined up with anything

How could line up the Top gear and bottom gear. If there are no marks on the bottom gear(besides the tdc mark)?If it advance the crank does the TDC mark on the sproket now become the new TDC? If the cam was advanced wouldnt it show one of the marks lined up differently? Im trying to understand what you did? Did you advance the Crank pulley then line everything back to dot-to-dot then reinstall. I assume someone that has done this will chime in.

I still think the cam timing is out and you might of done a bunch of damage. I would do a compression test. You have spark and fuel. So the next step is that cam timing is out. let us know. John

hers the way i did it in this pic, the only thing different in this pic my keyway on the crank snout is 2 more slots to the right for 4 degrees retard

There should be an 'A' or triangle for advance
There should br an 'R' or square for retard
these are on the crank gear. You should line these up with the cam gear not the stock mark.

ok instructions say "note the spacing of the standard keyway to the standard timing dot. this must be duplicated from the actual non-standard keyway you use if dialing in the cam. do not use the standard timing dot if using the non standard keyway"

so am i suppose to move the cam gear also in relation to how many spots i moved the crank gear? someone must have retarded a cam with a timing chain before.

I'm lousing at links try a search for 'crankshaft gear keyways' summit racing has a pretty good write up

Hopefully you can get away with just a few bent valves. Good luck John

what was the outcome ?
Did you get it running?

pdd

iTrader: (3)

no- i had to order new gaskets and a new crank bolt- i have it just about apart. i hope i can do the timing chain gear and crank gear right this time

i dont think i could ever deal with a double roller chain! too much confusion with them. Didnt one guy have one side tight and the other was loose and ended up bending all his valves and busting a piston?? not trying to discourage you, but they seem almost more of a hassle to the self installer than a perk Good Luck getting it take care of!!!

Agreed, bent valves is highly possible. I would think if you actually retarded the crank in relation to the cam, you might be okay.. so long as it wasn't much.. Might as well do a compression test to be safe.

Peace,

holy clusterfuck batman. no offence but i havent seen anybody have as many problems as you; pinched engine harnesss wire with the tranny, stripped crank, valve timinig off, low dyno results, ect

hope you can finally get things worked out, good luck.

o well-live and learn -all my mistakes benifit other people who use the search-i never did strip the crank, one good thing ill get her running though now i know what happened
this is the way im gonna retard the cam and crank

don't feel bad.i have a knack for screwing things up myself,lol.when i put my second set of heads on i got the coil packs on backwards.when i tried to start it,it fired and then went BOOM.right away i realized my mistake and changed them around and all was well.boy did i feel stupid,lol.

hmm, could of sworn you had a crank related issue, guess not.

do you have a degree wheel, dial indictator, ect? check out the degree walkthrough in the cam guide for more pics and info.
