Im looking for a set of rings and bearings, but I don't have a whole ton of money to spend. For a 400 Chevy, looking to eventually make 450HP and 500TQ and spin no more than 6500 max.

I saw these on ebay: http://cgi.ebay.com/ebaymotors/400-...hZ019QQitemZ8008522951QQrdZ1QQsspagenameZWDVW I don't know much about rings so is perfect circle a good company? or these http://store.summitracing.com/partdetail.asp?part=SLP-E-243K020&FROM=MG but these ones say only the top ring facing material is moly, the perfect circle ones I believe all the rings are moly?

For bearings Im looking at these http://cgi.ebay.com/ebaymotors/ws/e...STRK:MEWA:IT&viewitem=&item=110032063267&rd=1 or else the clevite P series???

Thanks

Perfect Circle has been around forever, made good stuff in the old days but hav'nt used them in a long time, I,m sure they would be fine but I use Speed Pro coated pistons and Speed Pro moly rings in my STREET engines. Never had a problem.

Yea this will be mostly street engine with draging every 2-3 friday nights. The pistons I have are speed pro's Hypers H615P...but are not the coated ones...Im hoping their wont be much diference with noncoated? BTW compression is looking like it will be around 10.5-11:1

That compression sounds a bit high for a street engine and pump gas.

Hmmm, any other commets?

I think ill use the king bearings and the perfect circle rings.

I have one other question, I will be buying a new crankshaft...I would guess that ovousbly means to use standard size bearings correct? OR should I buy .001 larger bearings as Ive heard this helps with oiling or somthing?

Most cranks are sold standard sized unless specified.



Make sure th rings you are using match the honing process. Moly rings on a out of round bore/hone glaze breaker kind job won't last long. It's proabably best to get those through you machinist.
