298....tr6060.....67mm@20 psi.....in progress!

See the bronze color and the circle around the edge, it's a bearing that is pressed in.

Technically speaking it's a bushing.

block was dropped off this morning! the said it didnt look to bad and will try honing it first. they will be using torque plates. so i wont know about pistons until they give me a call on the bad cylinder.

If you don't mind my asking, who did you take it to?

 

[one eyed willy]

Engine lab in Tampa. Cleanest and most professional machine shop I have ever dealt with! Great customer service as well. They did my heads on the last motor.

When I get my other parts together they will do the digital balancing up to 7000 rpm.

 

[one eyed willy]

Machine shop honed it to 3.555 to get rid of the bad spot.

Diamond fully coated pistons are $1150

Manley fully coated pistons are $799

Machine shop is holding onto the block until I get the pistons, then they will machine .020 over based on the new pistons. Supposedly the Manley pistons are pretty nice, havnt seen any reason at this point not to go with them.

 

[JeremyH]

Diamond has been good to me and my engine builder swears by them, thats enough for me to stick with them imho. That is a considerable price difference though...

If your just going to do a .020 overbore you won't need custom pistons though, right?

i run manley .020 over, no problems so far

 

[one eyed willy]

No, the .020 are hard to find but not custom. Will still take 3-4 weeks I'm told if I do the coated Manley.

 

[JeremyH]

.020 over bore is a standard size I thought didnt realize they were hard to find. When I bought my diamond pistons from the link above it has a drop down for bore size.

P/N 595520C-8 for a -14cc (9.51:1). This is the .020 over stroker production model? are these what you are looking for?

You can run standard bore pistons with that size bore. As long as the bores are straight at 3.555. I run 3.555 bore size with Manley 3.552 pistons. I have ceramic hard anodized Manleys in mine.

One difference between Manley and Diamond is the Malney pistons have a much thinner wrist pin, but you can get them upgraded depending on your needs. I run the 9310 pins with mine which are the top of the line for the Manley pistons. 9310 is harder than 4140 or 4340 whichever chromoly pins come standard with Manley pistons.

with the full coating and with the compression i was wanting they dont stock them. while they are not really custom, in a way they are becuase of the extra things i want. so they will need to be made a diamond and then sent to me. i have been dealing with dale at Modmax.....awesome customer service i may add, he spent a ton of time with me!

i was originally asking for 8.8:1 , so if i go with 9.1:1 then it may change things a little.

P/N 595520C-8 for a -14cc (9.51:1). This is the .020 over stroker production model? are these what you are looking for?

9.1:1 is the highest compression i want to run, i run 93 pump with 16-17psi on the street

they are torque plate honing/boring,.003 is a little too much i think for clearance. id like to be closer to .0025. plus i want them to go a little deaper on that damaged sleeve just to be safe. since im ordering pistons i dont want to take any chances of the pistons being too small once they show up.rather go slightly bigger and have it bored to match with no issues.

diamond also has a upgraded wrist pin as well for an extra $19 per pin.

 

[one eyed willy]

I believe I have all my data for pistons and rings.

Specs:
2618 material
.866 pin
3.75 stroke
5.85 rod length
9.1:1 compression
.020 over
Coated side skirts
Coated top
4130 wrist pins


MMR
$699 manley pistons
$250 coating
$140 total seal CS826425 rings (also recommended by total seal)
"Few days" turn around

Modmax
$840 coated Manley pistons
$190 Modmax rings
6 days turn around


Dale from Modmax has been awesome, so looks like I'm ordering on Monday.

 

[JeremyH]

Good choice I give as much business as I can to modmax, cutomer service is great and it doesn't hurt that they have good prices as well. I check there first whenever Im looking for engine related stuff. Just got my ati superdamper from them as well.

.003 is what Manley recommends on the modular pistons with moly skirt coating and .004 without. I see what you are saying about the pistons potentially being too small and by the time you have the cylinder honed to the ring specs the clearance would probably be closer to .004 which is a little loose when running the moly skirt coating.

What coatings are you having done on the Manley pistons?

 

[one eyed willy]

They come from Manley with the skirts coated ( which you probably know), I'm having them add the thermal coating to the tops. Wasn't real expensive so it should be worth it.

Next I'm hunting for bearings....

[one eyed willy]

Yup, those are the ones I was looking at. Good reviews from all I have read so far.

 

[aleborjas]

do you have stroker? then you need 18 cc's to get arround 9.1 or if you have stock displacement crank you need like 14cc's, i have never seen a manley platinum piston melted they are good. For me manley and Diamond are the best, i've seen many CP's melted too...

Dale Metlika is agood friend of mines he is a great guy to deal with...
