personally i would be careful about buying a rotating assembly for that cheep...balanced or not. most of what ive seen is 1400 bucks or higher. im looking at building a short block too. there is a point to buying a built SB, if you can save the extra money, it would probebly be worth it. I cant afford the extra 500-700 bucks right now to have someone else do the easy part, but thats only because i need the motor soon, otherwise even though i know i can do it, id probebly pay to have it done instead heh.

 

where are you looking at with rotating assemblies $1400 everyone i find is around $1800 with bearings

 

you can get something like this http://cgi.ebay.com/ebaymotors/FORGE...=p4506.c0.m245 and pay like 4-500 for a crank and have an assembly for 1400ish

 

dss has one for 1400 its there SX somthing or other. MMR stuff is on sale for 1600ish

 

Check out modmax racing

 

isnt the stock crank good for a lot of hp as is?

 

Our stock crank is good til like 600 crank if i remember correctly. So i mean for the security id find a cobra crank and buy that and then buy some decent rods and pistons and have it all balanced and you should have a nice rotating assembly for cheap. I mean around my area, cobra cranks are about $300. So you'd have a rotating assembly for like $1100 or so plus the $900 you're looking at a built motor for $2000...which is not bad. But you can get an MMR600 for $2400. But its all in what you want.

 

oh ok...idk why i was thinking 800 instead of 600

 

that is way to much for the shop to quote you that, maybe if you got a port and polish or something, i've called several shops around here, talking $110 flat for a bore, $75 for a compression test, $55hr for port/polish, and you supply the parts. wow. thats alot. and said, talkin balance $125, hell even $200 is still more than half.

 

I dont know why you were thinking that. lol You might have been thinking in lines of the MMR800 only being different from the MMR600 being that you get a cobra crank and you got a little confused. I dont know though. And it could be that youre thinking about your pushrod motor crank being good til 800. lol
