reground on my stock 3.4 cams/ engine question

[d.o.h.c]

i have my cams at crower right now and they need to know a little info. can you guyes help me out here is what they asked.

* What is the O.D. if your lifter (bucket) ?

* What is the valve stem size?

* What is the measurment from the top of the keeper (valve lock) to the tip
of the valave. We need this to see if we can fit a lash cap on the tip of
your valve.

* Just to make sure we ware on the same page, 3.4 Chevy V6 dohc. 4-cams for
one engine. Correct?

also i checked the clearnces on my rods to crank side clearance and some are 20 thousands. now the 94 gm manual say 7-17 and the 92 says 7-24 what should i go by and what are the difference. the engine getting the cams is a 94.

91-96 are 35mm, 97 are 33mm lifters. 7mm stem. .136" from the lock to the stem tip.

ben is the fucking man. thanks man i will e-mail him right now. sweet

Let me know on the lash caps. Comp makes some as well though im not sure on the length. I think they will work. I was checking them out for my solid lifter dream. At about 40 bucks each, its gonna be a dream:P

If you can get some stock specs from them, that would be cool. thunder racing doesnt know how to get a centerline if its not a V8 (what a freakin waste!). Im curious what specs they recommend as well.

hey,dohc, how much is crower charging for this(i didn't thing crowewr did regrins for owr engines).
hey ,ben too bad you live to far or i would let you built your dream in my engine.but,if you ever up to it ,i 'am wiiling just come up with some #'s.

[d.o.h.c]

what specs you guyes need. also i talked to brian crower. he gave me a price of 100$ per cam *4 =400 plus i had to pay 15$ for shipping back. also had to have a special box made for the cams to go from florida to california and not get ruined. so about 500$ for the whole thing. dj at crower told me that he would try to keep something stock and go 20 thousands on something else because it is going to be a turbo car. but for a regular regrind i think he said 10,10. yeah let me know what specs you guyes need. i will e-mail him and get you the info no problem. hope they run good

1991 Rod Clearance

Hey d.o.h.c.


On the 1991 3.4 DOHC
the ROD SIDE CLEARANCE IS 0.36 mm-0.64 mm (.014"-.025")
Check with GM to be certain of the right clearance.

Regards,
David Hayes

yeah my 92 gm manual say that but the motor i am rebuilding is a 94 and the gm shop manual say 7-17. but everything on the bottom end is the same. why they do this and do you think i ok with 19 on two rods.the rest are around 13-15

[SappySE107]

I just need to know the centerlines. I know GM spec is 111 and 112 but I wanna make sure.

[d.o.h.c]

WILL DO.

[your_I.D.]

[dohcfiend]

This is so badass. I can't wait to hear the final results of this.

Kudos to you, d.o.h.c

[d.o.h.c]

NEED HELP.

Ok just talked to dave crower and he is telling me that I am going to need to use some type of shim on the cams. I have no idea what he is talking about. he said that he is getting new lash caps but needs to know the clearances as far as the BUCKET goes. any body.

[your_I.D.]

just deck the cam carriers the amount crower takes off the base lobe
