my 428 progress and my old 292 GMC L6 has sodium valves,
« Reply #30 on: March 25, 2016, 12:24:23 PM »
...but they were much thicker stem, and the L6 was about 120#s open, maybe #50 closed  (well not that low, but i could open the valves with my hand when the head was on the bench, and it was built by a reputable shop, on and the cam lift was like 0.39 or 0.44, something really small.

Anyway, i decided in the interest of time and speed, to rebuild my spare 428 engine 100% stock CJ spec (0.030 over bore, std/std crank and rods), down to the stock CJ cam, except the intake will be either a correct for my 64 Galaxie C4 cast iron 4v (gulp!) that i have or the PI intake, and will use the Sanderson Headers. The reason for the stock cast iron idea was it matched the power range of the GT/CJ cam.  Also it has a fill pipe so i can run the stock red Baldy round FORD valve covers i have from a 1958 Fairlane 352 car.

I am picking up my 100% reconditioned stock 1966 heads that match the 1966 428 Tbird engine i have. Valves are totally new stock chromed valves, 0.15 over stems so the guides could be reamed out, not requiring inserts. Hard exhaust seats.  I had the heads, total cost $700.

I have a new 428 balance flywheel coming in the mail.  Jegs recommended the PRW SFI rated one with the removable weight (so i can put it on a 390), overnight shipping included with CA tax was $330.  I hope the quality is ok for a driver. New water pump and fuel pump and MSC items. $200.

I will then find another block (i dont think its worth it to sleeve my broken 1968 block.  Then I rebuild either build another 410/428 or a 445/462 with a stroker crank, and will use Jay's intake adapter, timing cover, the hot solid cam i have (or my 270H i have or a 282S style but on a 112 separation depending on the intended use.

PS i have a set of usable 0.030 over 428 pistons available now, but with domes cut down about 1/16 or 3/32 for sale.  Might be useful if someone offset ground a crank?  Not sure if they are cut enough for a 4.125 crank, i need to measure them.  Anyway price is $1.00 for the set of 8 (but you have to pay shipping).  I know this is a classified add, but i figure for $1.00 i could get away with it here.

Anyway, i hope to get the engine together this weekend, and with any luck, into the car.  But with no garage, and family activities, i am not sure how car i can get.

PS, i want to mention the importance of Coors beer: my neighbor came over to see what was going on, now my motor progress was going, and he offered me a cool one.  So i chilled out for a minute before put on the oil pan.  As i showed him the progress, i realized i had forgotten the oil pump drive rod!!!  Wow, that was a close one.  If not for the neighbor and a Coors, i would have had a big headache later!

Also during assembly i found that one reason the motor may have been pulled out of the truck it was in was because the damper had slipped!  It was 20+* off!  It must have been confusing to try to time to get to run right!

OK, realizing I don't have budget or time to build a 462 with alum heads just now, and I inventoried my parts, I decided to build a 100%stock 428 with a CJ cam and the PI intake. Infact I was going to even run the cast iron C4 intake, but I didn't have the bypass pipe and other plugs on hand.

I had my stock C6AE-R heads 100% rebuilt, used 0.015 oversized stems so we did not have to install guild inserts. Hard exhaust seats and new stock GT/CJ spring, 95# seat, 240 open.

I got it all together yesterday. Today I hope to pull the broken block out of the car.

Sounds like a great match for the car, and I like the PI intake for a stout cruiser.

Any chance to get headers on it, or maybe cast iron Ford shorties?

Headers...New Heads VS total rebuild on C8OE CJ heads - Your opinions?
« Reply #33 on: March 28, 2016, 12:19:45 AM »
Car iron shorties would be a great match, but...

For now I have Sanderson ceramic coated 1 3/4 tube Shorties, I like them OK. 3" collector, but they came with 2.5 reducers, so it's 2.5"  pipes down to under car, step up to 3" under car, 2.5 H pipe at back of transmission, 3 " magnaflow box straight through offset mufflers, then 2.5" over axel and exit to rear corners with turndowns, looks like stock.

That's good enough for me...I was mostly wondering if you were going to use stock manifolds, that should be a nice running machine!
