Camshaft - Emissions - 347 - Timing Set

[AnthonyR23]

Hey guys, so everything is going good with my 347 build, I was initially going to just have the machine shop install the stroker kit (bottom end) but I have changed my mind and am going to pretty much let them install everything that involves rotating or moving parts, other than clutch tranny back.. anyways so I asked what the next steps for what I should buy and it looks like they kinda need everything, it is my old neighbor who owns the shop (Dave), he said he wants to mock everything up just to check for clearance issues. So it looks like I will be ordering the rest, other than intakes (as I can do this part myself) intakes injectors, etc.)

So I went with the twisted wedge specific pistons, so I am definitely going with the twisted wedge tfs heads, 1.6 rockers, etc. For now I would like to order the timing set and the cam (until next payday) I am going with the trick flow billet timing set. With the cam choice, I asked Dave and he said that cams can be a learning curve particular with different engine combo's and that when it comes to emissions that I would be better going with a combo that says its emissions legal. He said that it is more likely to go over the top and recommended going with something that says its legal, getting an emissions test done to see how I do, then from there, down the road I could upgrade my cam, I kinda am inclined to agree as cams are pretty reasonable, It would really suck to be all excited to get the car together, then not be able to drive it because it fails an emissions test so anyways... I also filled out a custom cam form through crane cams, and they responded to go with cam part #444221 So here is what I am debating:

Trick Flow Cam part #TFS-51402000 (which is the cam that comes with the street and the track heat tfs top end kits) duration 275 / 279, lift .499 / .510.

Crane Cam Part#444221 (which is the cam the recommended) duration 270 / 280, lift .533 / .544.

Trick Flow Cam part #TFS-51402001 duration 286 / 294, lift .542 / .563.

B303 Cam duration 284 / 284, lift .480 / .480

Ok, so that's a start... So for the rest of my combo, I was told that I should go with the R series TFS intake for the 347, do you guys know if that is egr compatible... You know it's hard because, you look here for advice sometimes, and it is easy for people to say ya go with this or go with that. But honestly that would be great to go big all around, but emissions testing is a reality here in London, Ontario.

Any help would be great, I am getting there... the rest of my parts for the machine shop are pretty much chosen

28oz SFI pioneer balancer

TFS timing chain

Camshaft?

TFS Twisted Wedge Cylinder Heads

Roller Lifters ?

TFS Pushrods 6.7inch

TFS Roller Rockers 1.6

TFS Gasket Set

After the above parts I think I can pick up the engine and do the rest at home, I have a engine stand and hoist....

If anyone's interested here is what I've actually bought:

Stroker Kit - 347 Street Fighter Kit -
3.400 Probe Cast Steel Crank
5.315 Probe I Beam rods
Probe SRS 2618 Forged Flat Top TFS 4.030
Clevite77 Main Bearings
Clevite77 Rod Bearings
Perfect Circle Moly Rings

Fidanza Aluminum 157 tooth Flywheel

Oh, one more quick question... sorry for the long post... but can I use my stock roller lifters if they are in good condition and once I have all the parts have the shop check for the correct push rod length?? Or do I have to buy new lifters?

 

[AnthonyR23]

I read more about the crane cam and how it offers power without messing up the computer and its emissions legal.. So I went with that and the TFS timing.

i would go with new lifters. why chance having a lifter collapse after putting everything back together? that would kind of suck! they are only about $120

Explain more about the more power and messing with the computer,
I'm debating on the same cams also.

Crane CompuCam camshafts have special profiles designed to improve engine performance. And they do so without sending the computer into fits, or causing the stalling, surging, or drivability problems some "computer-compatible" cams are known for. They're 50-state legal for the applications listed.

Just looks like more lift than some of the other cams, google'd 347 and that cam, and a guy talked about that he just bought the car has about 500hp and is emissions legal... Its crane cams (compucam) part number 444221 from summit racing.

Personally, I'm sold on it, I filled out a custom cam form explaining my emissions constraints but explained I wanted power too for my 347.. that is what they recommended at crane cams!!! SWEET DEAL!!! I'm getting there!! Have to admit, it's nice to have options... but its also nice to have your mind made up!

Does anybody have solid info with this? I'm sure someone has had idle problems with comp cams and no surging problems with tfs cams?

how many miles on your stock lifters? I would just re-use them unless they are like 200,000 miles.

The b-303 is not emissions legal, and I don't think the TFS stage 1 is either technically, but I do think it should pass the sniffer. The E-303 is sold as an emissions legal cam, but personally I dislike the cam. Stick with the crane or even a stock HO cam.

Re: the emissions, in Ontario, it seems to be just the sniffer, so when referring to emissions, I don't think it is as strict as CA for eg. re: visual inspections... just tailpipe test... which I think is fair... I think if a car has a certain allowable emission... then if it passes then.. it should pass... I think the idea of looking at a part under the hood and saying that specific part is not emissions legal is b.s. .... if it passes the tailpipe test then it passes... luckily that seems to be the case here! So honestly... I don't want to have excess fuel going out, I don't want to have burnt oil... so really emissions testing seems fair if it is just a tailpipe test... I know with these engines, egr, smog pumps and cats.. are necessary to pass... which (for a street car) is fine.. the few hp you will loose on a street car isn't that big of a problem in my opinion... I would like to push 300hp rwhp and I'll be happy for my street car... sure 400 would be nice.. but I also want this thing to last.. and that extra hundred... equates the wear - tradeoff... so in my cam.. choices... visual or actual part inspection isn't that big of an issue for me.. I know that tampering with the actual emission control parts.. eg. cat's could be a problem... but I know a shop won't fail me for having a trick flow manifold!
