1969 engines are E Code. HP denotes Hotter cam and Windage tray mainly. No basic differences in engine in HP version.

Any 440 Block is fine. It is an earlier block as later ones have a thicker boss for attaching motor mounts. The ribs might help prevent cracking if the block is subject to freezing weather = Otherwise not a difference!

It looks like an older build but probably a good build if rust is not a factor!

As I remember, I ran that # head on my 440 Duster in the 90's. Stock offset Crane Rockers Back then. I always make my own pushrods so I do not know if the production ones would fit. A 590 Clay Smith Solid Roller cam was biggest that I ran with High Compression TRW pistons due to piston and...

I have heard mixed reviews about Firecore stuff. How much is the timing variations?

Distributor Shaft collars helps if it is not a timing chain issue. Check Distributor shaft bushing/bearing for side play. Is it just a degree back and forth or is it 3 or 4 Degrees. Be sure weights in Distributor move freely and do not stick if it is not locked out. You could try a bit more...

That cam is insanely huge for anything that will ever see the street longer than it takes to get on a trailer. it sounds like your Valvetrain may not accommodate the lift on your camshaft.

You must buy sight unseen from these Monkeys and return opf deposit. I have tried them again last year and they were worse than ever and more flimsy and warped yet. Scraped up from not enough Mold release and beaten out of the mold with a big hammer and wedge. I used to be a Boat Manufacture...

Yes Sir Generally a 6 Series. Usually an old Analog old style when i can find a NOS.

We run exclusively MSD Stuff. It is not as good as 20 years ago but still as good as you will find anymore now that everything is made offshore! No mod required on their Billet Dist. I do not use the ready to run stand alone.

In our flow bench testing the 906 flowed better than the 452 or 346 (That were about equal) by a significant margin. The "F" castings were the best and the "C" castings were the next best of all the 906 castings. The 516 old heads were the worst of all. I accumulated several hundred cylinder...

I believe 2.02 and 1.60. But industrial heads are basically thrown away.

The 62/63 Max Wedges had valve reliefs to unshrould the large 208/188 Valves on one side. the 64 Max Wedges had reliefs on both sides of the top of the bore. You could use a Head Gasket as a template and a grinder to put them in yourself and you would gain a bit of Air flow if your bores are...

I used C body Manifolds and had to offset cut one side to work and look correct on my 68 440 Valiant. Currently has 2 inch TTI's now and it is faster than with the manifolds even through the mufflers.

Everything my buddy Steve has every built is a Rocketship! I remember when he was a kid too young to drive, he would walk around the pits and tell everyone how he planned to kick our ***! Like the old TV Show = It ain't braggin if you can do it. His Dad "Don Wann" (His real name) was a good...

Nothing wrong with a 413 Industrial block of truck/Motorhome block after you toss away the Heads/Intake/Waterpump. In the 60s/70s I bored them always to 426 plus 030 and ran them in our Stock and Superstock Max Wedge race cars. They still generally soniced tested as well as a production 426 Max...

Never had an issue in 20 years with my 440 with those headers and Mopar compact starter with no insulation and in Nevada it is HOT! Optima Battery in trunk but top grade wiring and grounds.

They are new Indy for 440 stock block/heads solid adjustable that are 9.175. they cost me $80.00 and you can have them for that price. Way back them. Cup is 5/16 and ball is 3/8

I may have some new ones on the shelf in the shop. I will check today.

Brian and his Dad are one of the premier machine shops and engine builders on the West Coast!

Better off to buy Adjustable rockers and save yourself some problems!

Nope = Not at Zero Deck and a Flat top Piston!

Schumachers are now built and sold at Motech Perf. in Murrieta, California. They are a nice product and the owner Chris will go out of his way to help you. He did that for me consistently!!

The cold weather blocks that I have all have the 230 casting # Twice as large as regular 230 Block. The have consistently Sonic trested great. The other small letter 230 block = Not so much at all. Brandon 440 Source Web Site explains the Main Web difference very well.

I have always used a Aftermarket Block @ 750+ HP. I use 230 cold weather blooks on our Stocker but it is 475 to 500 HP.

Those would be an excellent choice and well worth the investment!

If the piston skirts are very worn = It is likely that the ring lands on the piston are also work which will destroy the ring seal! New cast pistons are not expensive. Also if the pistons are are more than 50 down in the hole (I have seen them 100 plus in late engines) it will really hurt...

There are several stock eliminator combos early to mid 60's that supersede to the 915 Big Block head and it is hard to find a nice set that have been sitting for years and do not have sunk valves and beat up seats.

I have sold several pairs of good core 915s for $350 to $400 in the last 6 months

By the part number it looks like a 3.9 stroke crank for a 440 Main size = Not a 400 for 3.75?
