I didnt know about sidewinders, and now I see promaxx as well? When did these come out? Ive done lots of searches over the years about aluminum BBM heads and never seen these

I called tod. I'm going to go with the sidewinders, and I think he'll beat summits price on all the other parts I need too.

Now I just need to pick a cam, intake and carb

Try Delta Cam, they are in Tacoma and can grind any profile that you can think of. BTW I used iron 906 heads (stock valves & ports) out of the yard on my 1st racer and the last cam I used was a DC 296 x .557 Mopar solid cam. The new racer has a Comp hydraulic cam with more lift and duration and it has 906 iron heads that were massaged by a shop in SoCal. The dyno sheets that came with the engine show a max of 514 hp on pump gas. It was not $2,000.00

I've lost track. Did you ever measure how far down the pistons are?

My pistons are down something like .150 or equally abysmal.

There is a member here that will hook me up with 440 magnum pistons if he can find them all. Currently he has 7, I'm waiting to see if he can find another. I'm ready to hone my block now, and the crank is being ground right now. When I get the confirmation on how far it was ground, I will buy bearings and rings

You might ask Todd to mill them to 70 or 72 cc to get some CR back. That might be money well spent if he is already taking them apart and checking them.. Obviously do the intake side too.

If the replacement pistons result in higher in the bore ring travel, that might be a problem.

If you cut them to 80 cc and cut the intake side the valve cover rail gets thin, at 70 I think it would disappear.

I think others have cut the Stealths to 72, but never done it myself.

Ive only installed a rope seal with the crank still in the engine. I used rtv where the seal ends meet each other. When installing a rope seal with the crank out, do you use rtv in the retainer before laying the seal in?

Yes & the Car Quest Victor Reinz JV551 rear main seal kit (just 2 halves & the goop) comes with a tube of it

Got the block cleaned and did the honing today. On closer inspection I saw that one of my cam bearings was gouged pretty bad. I've never had to replace cam bearings before, and a lot of the tools are fairly expensive starting around 120, so maybe more cost efficient to have the machine shop R&R the cam bearings for me

Its generally cost efficient to have them do it as the tool is expensive for the few times it is used (unless your friends tip you a bit for borrowing it if you buy one). You could redrill the cam bearing vertical feed holes to 1/16 and the ones that feed the heads to 1/8 which is plenty of oil for journals/journals that feed the heads & leaves more oil for more critical areas. probably not a dealbreaker in your deal and it'd be extra labor time for the shop or you could purchase them yourself then drill em & some shops squalk at carry in parts. Short version: yes let your shop install em & bring the cam in with you along with the block

If you have a shop do it (smart move) take your cam so they can trial fit it after they install the cam bearing. Big block MOPAR and small block Fords are the hardest out there to get in and NOT get a tight bearing.

Im thinking the same thing.. The price sheet I looked at for my local machine shop is $11 per bearing and their is most likely a shop supplies flat fee on top of that, so total cost is around $100 after tax

I did ok on my hone job as far as I can tell. Couldnt nail down the ideal 45 degree hatch, was closer to 30 degrees. Some cylinders had steady hatch, but some of the areas I reamed wouldnt blend completely with the rest of the cylinder.

For that kind of money I would suggest springing for the tool. I just checked ebay & for 150-200 you can get one & the one I have was one of those very reasonably priced ones. I ain't used it yet but I dont anticipate a problem. EDIT the pattern looks real rough in the pic

At this point you are just a punch and pistons from a totally fresh short block. Not finishing the deal might be penny wise and pound foolish.

Can't see picture at work , but not surprised , this is what happens when a novice uses a ridge reamer.


For the record, I'm a novice and after having to sleeve a block because a hack went at it with a ridge reamer I'd never recommend it''s use.

Again, a photo of metalwork can be really deceiving. That pic makes you think some freak went after the bore with a piece of 40 grit paper. That can very likely be the camera picking up reflections and making things look worse. In reality, the bore can be smooth as a baby's bottom and we'd never know.

There is no sign of the ridge reamer work so it could either be a nicely done job or an excessively deep cut.

The bores should be very smooth to the touch. I don't see any trace of oil in the bore. You needed to be oiling it before, during, and after honing. If not, you'll have lots of blow by and the rings may never seat.
