Wow, great score, those parts are gonna come in handy!! Is the cage staying in the car?

Just the back half behind my seat, even removed under hood bars

Ok the 413 I was going to put in my 55 d 100 after tearing it down looks like a little to wild for the truck, but since the RR is tubbed and stiffened I thought put it in it.The sump has been extended and the oil pan deepened 3 "the heads have been ported, don't know if I should use them they're 509 casting, I have a set of 906.Crank had a number on rear throw and connecting rod bearings .10 cut of crank.Pistons are Alcoa stamped on edge and inside stamping Jahns?

 

[Beep!Beep!]

As you can see adjustable rockers and porting on the 413. will that be of much benefit if I use my edelbrock 6bbl. Intake because I'm not going to port it out and the lifters are hydraulic. Would it be better to use my 906 heads? The cam in the 413 just has a 29 casting have no idea what grind it is. The timing gear gotta go mopar plastic. The engine was packed with grease doesn't show wear maybe run a pass or two bearings, lifters, I can still see honing marks in cylinders.Lifter has vl-8 on it. I'm going to give you low down on 440 looking for input on which one would be the right fit for this car .Thanks

Ok here's the D 440 hp block bore .30 trw pistons, needs more work and money to get it back together no lifters, lifter bores need cleaning up, had a crane cam zip-510-anc on one end on the other end ac3266 anyone run one of these cans good grind ,how did it idle ?Pistons trw L2295. .30 over with 906 heads wonder what comp. Ratio?

 

[Beep!Beep!]

So the 413 gaskets and new double roller timing chain kit and its running comp. Ratio looks to be high.Maybe not to crazy if I put 906 heads on it or stick with509 heads.Since I don't know what cam is maybe add that to agenda. Now D 440 hp 906 or ported 509 heads has trw L2295 .30 pistons ,need block cylinders and lifter bores done. RINGS &Bearings gaskets kit cam and lifters ,crank on both motors good. So what combo do you guys think or mix of parts from this mess would you build for best results for performance the hottest build going in 70 RR and other goes in the 55 truck ?

Do the 440 and use the better heads, wedge guys will which heads are best. Compression 10 to 1 a hair more?

 

[rolling_Thunder]

The TRW 2295 pistons are listed ~10.3 compression with an 88cc head. Granted a lot of other factors (head gasket thickness, actual head cc, etc) dictate actual compression but that's a good baseline.

Crane cam ZIP-510A-C --- 254 / 254, 112* LSA, .510" gross lift.

Not sure if that's the same as your ZIP-510-ANC or not

The 509s are heavily ported and have the adjustable rockers if you scroll back you can see the ports but I'm using unported 6bbl intake

Ok so do you know what kinda idle it would be most of my experience is factory cams

I lied the 413 according to motors manual stock bore is 4.1875x3.75 stroke ,the bore measured 4.230 what cubic in. Would that make it

Sorry didn't see your last question just the back half of the cage the rest had to go not flexible enough for that

 

[Beep!Beep!]

Ok thanks for your input for my 70rr I'm going with the 440 it's bored. 030 has trw 2295 pistons I'll use the 906 heads maybe bigger valves after I have them checked. I talked to Dave at Hughes ordered hot street cam#seh 2832bl-10 lift 530-536 110deg. Sep.1106 springs 5003 lifters & timing chain about $520 to me. 6bbl edelbrock, hedman headers, just hanging around, found them locally $150 2 yrs ago ,1 3/4 tubes .Hope they fit!

 

[Beep!Beep!]

Have another question looking at summit they have several options for main &rod bearing, has anyone one used king brand,mains $80 rods better priced than others claim to be for performance engines? Also piston rings type of material brand good and bad? Thanks

 

[Beep!Beep!]

Look what the brown truck brought today! My cam lifters etc!

I've used the king bearings. Perfectly good, nice quality. They make a couple different kinds, Tri metal etc. pick what you need. If the engine was bored and built before the bores might be nicely in spec but no longer perfect. Given that situation I’d use cast iron rings. If it was a fresh bore etc you could use something else.

Being the "all things 6bbl" fanatic I am, I can say that the Edelbrock/Chrysler style dual plane 6bbl setup truly holds up very well against modern carbs and 4bbl performance intakes, for overall performance, horsepower, and TORQUE, and driveability on the street.
I did tons of research and comparisons as I am absolutely always going to feed whatever is under my hood with 3x2 of something.
Once the Weiand 6bbl intake got its hooks in me, I haven't been able to shake it, and got one, but I need a different hood for it to fit.
I think you will be happy with the 6bbl, but I definitely would recommend the Promax metering block for the center carb, and jetable metering plates on the outboard carbs, and the angled idle mixture screws throttle plate base for the rear carb.

Not commonly known, Holley made a set of carbs for the six pack with side floats and metering blocks so you could change the jets. Best part was all were pumpers, no vacuum secondaries here. I set one up for a friend in a sixpak Bee, absolutely stunning throttle response. I don’t think they made those for long, early 70’s only I believe.

Mechanical linkage, 500 cfm outboard carbs, and a 500 cfm center, all w/accelerator pumps, is that what you are referring to?

Yes, exactly. Never seem to hear about it but an awesome setup.
