BBC blower pistons.
 

Anyone running these Manley Platinum series?

looks like a good piston but i have not used any,j&e makes some nice blower pistons,i have used quite a few sets with good results.

if you use these you will truly be a manley man!

Tks mike I figured you'd post. I believe MT mentioned he used JE pistons also but don't recall if they were ceramic coated or not. I'm trying to find a good thick crown with the top ring down the right distance. The manleys top ring is down .350 and has a .250 thick crown which doesn't seem real thick but might be normal. Something I've never really looked into much to be honest.

I would be willing to try them. Cheaper than the JE's and you can have them tomorrow instead of waiting 3 weeks

yes joe,s engines have j&e if i remember correctly,no coating.i built the short blocks for him 4 or 5 years ago.the manley piston looks good,i would use it for sure.

if using a shelf piston from j&e i usually have them in a few days.

YES... I am.. Look decent..

a bit heavier than a JE but they were quite a bit cheaper.. I ordered them through www.cnc-motorsports.com and they were drop shipped directly from Manley.. :)

i just got some pistons from them for a 509 i am building,130 dollars cheeper than summit,did take 2 weeks to get them.

I've been hearing a lot of good things about Ross pistons lately also. Actually couldn't find one complaint in SC or NA build. Part number 85070 flat top for a 4.530 bore - .010 in the hole - .042 head gasket, Ross is claiming 8.5:1.???

Any flat top -3 cc at or near the said bore I typically get from 9.0 to 9.6 depending on gasket etc. I'm not going more than .010 in the hole.


.075-.080 head gasket would be more like it to get close to 8.5
