Perfect car for a screamin 352!

I agree. Maybe we should all tip in for Brent  :)

I'm all for some donations at this point. 

The botched crankshaft grind put me in a bind.  It was gonna cost me about $1500-1600 to find a 361 crank, ship it, have it ground, then ship it back. 

At this point in time, I just want to move forward on the thing, so I'm having a 352 crankshaft ground .010"/.010", and I'm putting another set of pistons and rods in it.

Alright.  Don't even know if it's worth posting anything anymore, except for a written record of the method to my madness....

Snagged a cast 352 crank.  To get things going quickly, I bought a set of Molnar FE rods and ordered some Racetec pistons.  1.900" compression height, flat top, 1mm/1mm/2mm ring pack. 







Switched cams again to a solid roller.  Yeah, I know.  Still gonna use my non-adjustable rockers to give them a workout.

Measured bearing clearances and since the crank is .020"/.020" with zero bearing choices, I had to send it to my crank guy to have the journals massaged.

Heads are done.  These are the original heads that came off of Junky Junk.  2.080"/1.600", 5/16" stem stainless valves.  PAC small diameter valve springs set up at 270/670, with Manley titanium retainers.  Compression ratio will be right at 10.5:1.



Carb pieces are on their way back to me.  I had Drew recolor and replate everything.  Can't remember if I've posted this before, but I snagged a Holley 3 barrel, 1030 cfm.

My prediction is that it's going to behave very differently compared to last time we had it on the pump :)

I think you should try the 500 2 barrel, it was winner that day!

Any cam timing picked out yet?

Man!

Those are some tall pistons! How much do they weigh?

Do you have flow numbers for the heads you're gonna use?

Is it going on the dyno soon?

Tommy, the weights are written on them, about 550g. 

I do not have flow numbers, but based on what I've seen with these heads in the past, they're gonna go about 250cfm with the current prep.  I wasn't too focused on making the heads work at this point as I plan to let Joe port them after the first dyno session.  Should make a night and day difference. 

It won't be too soon.  Got too much other stuff that needs to get done before it.  Hopefully this fall.  I have everything I need, just need to make time.

Maybe it is just me... but I sure like the look of those Diamond pistons! As for the RaceTech or any other, do you see any downside to the 2 mm oil ring versus 3 mm or 3/16? I had a pretty smart guy tell me he didn't care for them, didn't explain why though...

So far so good on the 2mm stuff.  I run a lot of Mahle PowerPak series pistons in my 445's and they come with 1mm/2mm ring packs.   The entire ring pack weighs less than 30g.   As long as the hone job is good and the engine will seal up, I see no downside to using them.   I haven't used anything thicker than a 3mm ring pack in forever and when the 2mm is available, I'll usually hop over to it.

The Diamond pistons with the aluminum rods was a very nice combination of parts.  Maybe one day I'll get to try them, but because of the crankshaft fiasco, it is what it is.   I just want the thing on the dyno and making noise.

Carb is almost finished.....

Drew did a good job on replating/recoloring the parts for me. 

Converted everything to screw in bleeds and screw in IFR and PVCR. 

Gotta put the needle/seat assemblies in and I'll be about done.

I can see the light at the end of the tunnel....

Waiting on T&D to send parts for a high riser build and got the Thunderbird 390 torn down, so I turned to the 352 for a little bit. 

Calico sent me my main bearings back so I got those in, crank has been touch ground to adjust clearances, and it's in.  Stabbed a piston/rod in #1 and #5, then set about degreeing the camshaft and checking piston/valve clearances.   

I have one of Jay's adjustable timing sets and his 2-piece timing cover, so my plan is to change cam timing on the dyno.  I milled the poop out of the heads to get compression up and had to mill one head more than the other, so that meant that I spent about 2 hours yesterday changing cam timing, degreeing, checking piston/valve clearances on two cylinders/two heads, changing cam timing, degreeing, etc, etc.  Finally got that done.

Got all the pistons/rods in, custom Racetec pistons, Molnar rods, and Mahle 1mm/2mm piston rings. 

Timing cover is on permanently. 

Melling M57B pump is in there with an ARP drive.  Then bolted on one of my stock-appearing oil pans with the trap door oil control feature.  I don't expect this to be any kind of replacement at all for a nice, deep sump race pan, but it's on there. 

Waiting on Cometic head gaskets and my lifters to show up, then I can work on the top end.

Not too excited about the color of the valve covers and intake, so I'll have to think a little more on that.  Otherwise, it's starting to look like an engine.  Obviously the 3-bbl carb won't work with this intake manifold without a spacer or some plenum divider work, so I need to make up my mind on what I'm gonna do there too.

Looks like crap.  Maybe Chevy orange is more in keeping with that level of work.  ;)
A careful study of failure will yield the ingredients for success.
