Interesting, I'm guessing they're just cut down the middle height wise, flipped around and re-welded? Thanks again for putting up with all my stupid questions.

Exactly. A cheap set of new eBay steel covers and they worked perfectly with my roller rockers on my Malibu until I got the aluminum covers modified to clear the AC box. Not pretty but functional and not $300+

Stock '75 is 1.173" on all lobes
Stock '73 is 1.185" on I believe the intakes, and 1.200" on the opposite lobes
My CMD is 1.100" on all lobes
My roller cam is smaller, but I don't remember the size
Thanks!
I got 1.106" on mine, this looks like reduced base circle compared to stock. Where did you get your chrome moly 3/8" 0.050" longer push rods for $73?

Comp Cams 8712-16 bought from eBay from an individual. I got lucky. I would measure before buying. Your needed length may be different.

That was a sweet price you got them for. Those are $200 pushrods new. I will probably just buy a set from Cad Company, they sell an oversized set of push rods for reduced base circle cams. I will mock them up to check on length first, of course.

I didn't mean to threadjack your build:
But since you asked :):
Stock rockers for now. I am under 0.500 lift and will limit the motor to 4,800 rpms. This is my #2 motor that will go in my '61 Cad.
This one is a 507" w/ late model flat tops, home ported 425 heads, Ported stock dual plane intake, rebuilt modded Q-jet, small 216 duration cam, cheap EBAY block hugger headers, stock converter, Eldo pan, and HEI. This one is just a CSOB special. I'd like 520-530 ft-lbs out of this one, don't care about HP. I only have about $350 into the whole motor now, including the rebuilt long block. I still need to buy the headers, valve springs, and pushrods. I don't have any 120 cc heads, is the reason why I am using the 425 heads. Whoever rebuilt this engine put in flat top pistons in and used 902 heads. The motor looks like it was never successfully fired up. When I bought it had rust under the valve covers from sitting with water in them, and 4 or 5 bent push rods. Most of the valves were stuck in the guides from rust. I didn't find any rust or pitting in the cylinders and they are still cross hatched. No carbon on the pistons. Or valve marks on the pistons. I bet whoever tried to start this motor fried a starter :laugh: with 13:1 and 8 or so stuck valves.

My #1 motor going into my '69 Truck has Stage III Cad Company rockers. I am porting the 902s and will put 2.11/1.77 valves in them and put them on this motor. It already has a decent cam, valve springs, Edelbrock intake, MSD distributor, and Sanderson headers.

I got the valves seated in one head today and got that head bolted on and torqued down. I am not looking forward to porting that other head. Ain't that how it always is? And my reversed valve covers won't clear these rockers at full lift. So back to the drawing board on that one. The Sandersons that didn't fit my Malibu should be fine with this swap.

What's that other block behind your new motor?

Those rockers are HUGE. Did you try a double gasket for clearance?

Double gasket would get me close.

That is one of my spare 500s.

I got the oil pump body modified. Plugged the bypasses and added a high pressure spring. Tonight I’ll clean and drill the gears, and bolt it on.

Spring is a Canton 22-190 from eBay at about 10 bucks. That idea came from this site.

I'm of the opinion that oil pump bypasses like these were designed for sh1TTy oil and filters, and tons of wear that went along with them which blocked filters and required bypasses to keep from blowing the filter off the engine and onto the road. I had a 390 Mercury that did it a couple of times. Filter gets plugged, bypass opens, and you are sending all of the leftovers back into the engine. Light weight oils, few large wear particles, and on average way too frequent oil changes don't really let that happen any more. I've blocked the bypass on all of my Buicks in the past and never lost sleep over it. I thinks Cadco sells something like this as a 'blueprinted' pump. Some who has purchased one might chime in differently.

The drilling of the gears with a 0.062" or smaller drill bit, only on the end of the gear that rides on the solid pin about 3/8" up from the bottom is a modification that I did on my 430 and 455 Buicks which were apt to gall the gear to the pin. Of course a Buick only had one stationary pin. I drill both on the Caddy. Probably not needed but it makes me feel better. I have read of others doing it on Caddys. Same reason I did a Buick style distributor gear oil modification on my Malibu engine with roller cam. The factory oil slinger will be enough to keep me happy on this build.

I guess I'm going to blow the budget and order a new Edelbrock intake. I don't reckon they'll be getting any cheaper and I can't seem to locate a good used one that isn't new price once shipping is included.

Got a nice used Edelbrock from KZHurley. It's getting closer.........................I don't know of anything else major that I need at this point other than a driveshaft and a floor shifter.

I am liking this thread. I ordered the spring. I remember a detailed write up on the oil pump here but have yet to find it. I believe it was with a distributor write up too. Anyway, I am looking forward to this read.
KZ is a good guy. Glad to see you got hooked up with a nice intake.
