1967 Camaro 327 Pullys Don't Align, Belt Trains

I have a 327 SB Chevy Camaro Convertible. Belt pulleys don't look like they will align.
I have the Short Water pump. The PS bracket bracket has 3 engine mount bolt holes. Is the bracket correct?
I ordered 2 pulleys that were for this car, but they don't line up with the Power Steering pump pully by about a half inch. Did get the wrong crank and water pump pulleys?
Both the pulleys I have are doubles.
The power steering pump mounting bracket is installed under the engine mount as designed. I think the Water Pump pulley should be a single type based on the Camaro assembly manual in UPC 6 A. What pulleys do I need and what parts book has them?
Will that fuel pump to carb have to be cut or is it totally wrong? Thanks. Joe

Pump to carb line is for a Quadrajet carburetor. Camaros carburetors never had that style of float bowl even on engines that had a Holley carburetor. As far as pulleys camaros.org/pdf/pulleys_67.pdf

Looks like you don't have the 3rd groove add on power steering pulley on front of your crank pulley. I can provide a part # later. You need to know if you have deep groove or standard pulley because the add on pulley is different between DG & standard.

Previous post is right Chevy never used a 4160 style Holley with a banjo style swivel inlet. Nobody will have a hard line for yours. I have made them but all brake andvfuel lines are double flared inverted flare fittings for safety. Unless you have double flared hard lines before there is a learning curve involved and special tools to buy.

I would convert your front float bowl to a 4150 style center hung float bowl and buy the 3 pc hard line for a first gen Z28. You will need an inverted flare male plug as well to plug the rear float bowl line port on the brass block bc you don't have a rear fuel inlet. Otherwise your option is a rubber hose, which would be the ladt thing I would do. I have converted several 4160 into 4150 carbs. You would only have to do your front bowl and it has a metering block unlike your rear so it's fairly simple. Can provide a complete list of parts needed if desired.

Provide us with your current pulley part # s and I can tell what you have from that.

Or you can try to find one of these to fit the carb threads to use AN hose & fittings.

The other end needs to have an AN to IFF fitting to adapter to the current line.

Since my Holley doesn't have a fuel inlet filter, I found an external filter to mount to the AC bracket. The filter gets a NPT to AN adapter fitting on outlet side and a IFF to NPT adapter fitting on inlet side. The -6 AN hose will be made to fit the distance and clamped to prevent excessive movement. It will be kept away from engine to prevent heat absorption. I have Thermal Barrier sleeving to put on hose.

OP, my 327 came with triple pully for crank and single for WP. I used the same pulleys for my BPE motor, short WP. The middle groove on crank pully is not used. I assume it was for either AC or Air Pump, IDK as I have neither. Front groove is for PS mounted as yours is.

While not the same carb as yours, I also did AN fittings and SS braided hose with inline filter, Edelbrock.

Your heads are taped for accessories, I used the PS hole for a spacer to stand the fuel line off the motor using one of those unused holes.

Crank 3rd add on pulley standard depth groove is GM # 38744161. Deep groove 3rd add on pulley is GM # 3916385. They are not interchangeable even though they will mount up, if you use the wrong one they slightly hit each other. You also need slightly longer bolts to mount this inside & in front of your 2 groove crank pulley into the 3 holes in your balancer. This is the deep groove set up & utilizes a cast deep groove PS pulley. The standard groove uses a stamped steel PS pulley. It also shows the HP Z28 PS pump saddle bracket that uses the 2 holes next to balancer and the seperate rear PS pump bracket that attachs to engine mount.

Mine is not deep groove. The Add on Pulley is $173 at National Parts Depot. Is there another place that would have it cheaper? Is is at National Parts Depot part #C-0659-10 for $173.03? Thanks.

Where would I get this pulley? Is that pulley you have really two pulleys? I looked in several popular Camaro Parts catalogs for it and cant locate a duel pulley with that space in the middle.

3751232 and 19355268 interchange. 3751232 is available all over, for around 30 dollars.

See I have been beaten to the punch.

Don't let anyone steal an extra $140 dollars from you when you won't even get a kiss.

Used parts work fine, day in, and day out. Don't get hung up on buying a 'new' pulley.

OP, my 327 had, now on my BPE 355, the stock 1 piece 3 groove pully. car was shipped to CA originally so I believe it "may" of had a smog pump, IDK. However it also did have what appears to have been dealer installed AC as there are 2 holes, now plugged, in firewall where a under dash AC unit lines were run.

My point is GM did make a 1 piece 3 groove crank pully. Currently my center groove is not used. I have PS using the front groove and Alt/WP using the back one.

hard to see, but this is pic of my 3-groove pully

Once again, if you are having a hard time finding Camaro parts, try looking on the Corvette sites. The Corvette guys are WAY more particular about original appearance and quality for show purposes. If you find the part you are looking for, you can use the Corvette price to gauge value against some other parts supplier.

I've bought some Camaro not available parts from Zip Corvette and Top Flight Automotive.

These guys have all the tiny bits and pieces that are unavailable on Camaros, but apparently everyone needs on a Corvette.

Joe, sorry I dug through the few boxes of parts I have left and no pulley. It must've hit the trash can although I don't recall.

Unlike my brand new KYB Gas-A-Just shocks, those couldn't hit the trash can quick enough!

Would you be able to tell me what cooling fan and spacer I will need once I get this belt/pulley issue figured out? This is the crank pulley that I have from a guy who is very knowledgeable. My water pump pulley is also standard size with double groove and I think I need the add on pulley, then fan and spacer and bolts correct? I have Power Steering and no AC. Where should I get these parts?
Is that fan I have even for a Camaro? The hole is too large on this fan. THANKS for the help!!! Is this where I type followup questions?

Next I have to connect the Mallory Unilite Distributor to a American Autowire HEI engine harness. Anyone know what that should look like? Send picture or suggestions.

My stock 327 did have a 4 blade fan but the index (center) hole was smaller than the one you have. That spacer was about 2" long IIRC. You want the fan 1/2 in/out of shroud

Personally I would put the 7 blade fan and a fan clutch on.

IIRC, the Unilite distributor does want a resistance wire so if your new AAW harness is for a HEI distributor, it would not have that. You would need a Ballast resistor. Check instructions for Unitilite distributor to confirm if it needs a ballast resistor or resistance wire.
