Never thought you'd see me posting in this forum about engine stuff, eh? Well, with my ideas already in place on what I want to do with the interior, it's time to plan the engine while I impliment the plan on the interior.

Point blank, I don't have enough for a supercharger -- although $3000 for one doesn't seem that bad from FFF, Inc. Right now I'm looking at Full Throttle Performance's prices, and I'm quite happy.

Anyway, to start the "engine modding" I'd like to start with some internal engine work. Cam, port and polish, etc. I don't know **** about engines, so I'm just looking at what's available for my engine. H8 3.4Ls :banghead:

First thing's first, I'm looking at the Comp Cams K-Kit (Complete Kit) If I were to go with that, what exact secondary stuff would I need? Will this give me a nice lopey sound on the exhaust as well? I don't want something too radical, but I don't want a cam that's not going to sound, well... lopey cammed sounding (You guys know I'm appearance first, performance second lol) I know Caleb went with all CompCam stuff, so I would assume they're quality products. Out of the camshafts listed for my year, what would be the best for what I'm looking for? I'm guessing the 110* would give more of a lopey sound, but that's just a guess. Also, wouldn't I need pushrods and rocker arms too?

COMP-16.115.4 CompCams Hydraulic Flat Tappet Camshaft

*

1993-1995 3.4L V6
*

Duration (Intake/Exhaust): 192°/200° @ .050"
*

Valve Lift (w/1.5 Rocker): .390"/.390"
*

Lobe Sep. Angle: 108° that would be a decent choice, won't be real lopy (when you get alot of lope you get other issues) you don't need rockers or pushrods unless you want to change the ratio of the rockers (might be something worth doing later down the road) I wouldn't suggest much more than that cam for you, the next step up will set trouble codes, and really should have a pcm program (even teh smaller one may set codes periodically)

Second question is will this require premium gas, or would it still run decently (*read: when not at the track*) off regular?

archemedes

I'd suggest premium unless you have a scanner to see what your kr would be so you don't kill it

meissen

Hmph, not the answer I wanted to hear lol, ah well if it deserves Premium, premium is what I'd use.

If you P&P the head's make sure you do the upper and lower intakes as well. On the 3.4 they absolutly suck and doing just the heads won't help you out a whole lot.

If I tried to do this myself, would a dremel be suitable, or should I just pay to have someone do it? I have a book that talks about how to port and polish, just don't remember what tools it said were used.

When I had my 3.4 I talked to Tiago from FFF because he does that himself. That's what I suggest.

archemedes

a dremel will do it eventually, but they don't spin fast enough to do it effectivly (a guy on nasty z28 said it took a week to do port match his intake with his dremel)

you people don't know me that well cause I don't post on here that often.

But if you honestly want to mod your 3.4 well, dont just port and polish -- swap the heads. you'll be better off in the long run.

As for 108* not being lopey -- dont forget we are talking v6 here, the 108* might be more lopey than you think...

And not wanting to sound like a knowitall -- but you need to be careful when you port and polish. There's a reason that it costs a lot of money. I still think that starting with the aluminum heads is a better option than straight out porting and polishing the iron ones, and you should ask tiago - he agrees with me, because the "stock" form aluminum outflow even the fully ported iron (my heads flow better than tiagos and i havent touched mine and he has a 900 port job)

just some info. dont wanna see people throwing their hard earned money at something and not getting the results they want.

I think the 3.4 has more potential than people give it credit. GM just stepped up to bat late.

Question: To replace cam, valve stem rings & maybe pistons, Would the engine to my 94 3.4l have to be removied? or not? This is a pretty big job isnt it?

black34v6

yup.

archemedes

you technically could do it without pulling it, but it's a ton more work kind of like putting an elephant in a yugo

black34v6

thats an understatement...you really can't take the pistons/rods out of the engine without taking it out of the engine bay.

the oil pan is only like 1" above the k-member.

You'd have to remove the exhaust y-pipe, then raise up the engine to remove the oil pan, and keep it suspended while you take the pistons out from underneath, while keeping in mind that the engine would only be like 2-3" above the k-member. it'd be near impossible and i think highly improbable that you would be able to get all the pistons/rods out while the engine is dangling above the k-member.

It's a much easier task to just remove the engine, do everythign you wanna do to it while its out, and then put it back in. only takes a few days to do the whole process (taking your time) and its really not hard as long as you watch what you are doing (I've taken the engine out of the car and put it back in through the top (removing the hood) and that was with having NEVER removed an engine before!)

Good luck in your project.
