THAK YOU for that welth of knowledge...
btw I picked the block up last night.. looks nice I just need to pull the cam out of it and get her on the stand ... however it looks like I will have to bore .030 over so I can get the pistons in.. the only ones JE or Weisco have are .030 and they will knock comp doewn to 8:1 if I use 72cc heads
Dave
There is a good chance your block will have to be bored anyway. BTW, a lot of machinists want you to provide a piston so they will be able to hone the cylinder to the proper clearances. In addition, it is a good idea to have the block sonic tested for cracks, align bored and decked to zero so you can achieve proper quench. Do you have a good, reliable machine shop lined up?
yes I do.. I plan to get the pistons then send it in to get all done.. bore clean up new freeze plugs etc..
now will I need a balance job or not on the 350's
Dave
Absolutely, get the rotating assembly balanced. That's a critical part of building a good engine. If you buy your crank, rods, and pistons as a rotating assembly kit, you can order it balanced for a small extra charge. If not, have your machine shop do it.
now wont I need the flywheel as well to be balanced or not.. cause I plan to do a 4-5 spd manual trans...
or do I just need the bolts, timing set, crank, rods, pistons, bearings, cam, crank pulley
or in otherwards WHAT ALL do I need so I can get the engien balanced.. cause this has to be done before assembly correct
Dave
On an internally balanced motor, the damper, flywheel, clutch disc and pressure plate can be balanced separately from the rotating assembly.
ok so unless I am wrong this means I only need to have the crank, rods, pistons, maina nd rod bolts, and bearings balanced right... or do I need the timing kit and the cam balanced too?
Dave
Only the rotating assembly--crank, connecting rods, and pistons. That way, the crankshaft itself is balanced and it is turning the same weight for each cylinder. I should be balanced within one gram for a high performance engine, and it should be balanced as close to zero as possible for a race engine--usually within 1/4-1/2 gram is considered acceptable for the extreme applications. You don't balance bearing as they do not move.
and I dont have to balance the cam or timing set (chain and gears)?
also when I buy the rods I want bushed rods right not pressed??
**nevermind I looked back and read the answer to this question already**
Dave
You do not have to balance the cam, timing sprockets or chain. If you are going to run a manual transmission, you might want to inquire about the need to balance the flywheel and pressure plate. I have not heard of this before, but I run an automatic and don't deal with manual transmissions so I have to admit my ignorance about this. BTW, have you thought about a tranny that will take the kind of hp and torque you are going to produce? You might pose that question to the guys on the performance forum at www.chevytalk.com . There is a lot of expertise available there.
well I just like a manual but a nice auto could work
well I boght the H beams today for 300.00 (set) and the eagle crank for 144.00 so I just need to grab the SLP JE pistons for 430.00 and some rings and then the harmonic balncer and flex plate then I can get the block machined and balanced
Dave
If you can buy these turbo's for $ 300 new each I would like to order about 10 of these.:)Quote:

the cost will be in the custom headers.. as for intercoolers I get them at a low cost too..
thx for the answers to the rest of my questions.. im not insulted at all... but I do have an idea and wont bend this is something me and my wife REALLY want to do all I am asking for is a nice group of guy like yourselfs to lend yoru mind to help me with figuring this stuff out and getting my project to life :)
thx agian guys I like this place alot!!
Dave
lol... I cant get my hands on that many at one time.. besides mine first ;) lol
it depends on the trim and exact wheel as well.. but they range between 300-500 a turbo usually NEW
