can decide
 

im wanting to rebuild my 454 and bore it to a 468 but a can't decide whether to keep the stock rods or not. av'e heard that stock will still out last aftermarket

You have answered your own question,... :D

alright so you agree on stock rods then wat about crank and heads (im not going alll out on this motor)

I tought you just wanted to rebuild,..I didnt know you wanted
to hop it up too.....sorry

If you have the money,..buy a rotaing assembly
eagle /eagle/ srp/je.
other wise you could just have the rods checked /resized/ bushed
crank checked , cleaned, polished,.
and a good set of forged pistons.

heads you could just get the exhaust a the next size,
with better valve springs,..

ok thats what a was planing because a rotating assembly for a big block costs a pretty penny and i aint got too much of that but would that 468 bolt up to a turbo 400 trans

Yes,..you can bolt tranny to the chevys sbc or BBc
powerglide, t-350, t-400

thank you alot

If you are going to buy a rotatin asy, get a 4 1/4 stroke and make a 489/496 out of it. And only use a th400 behind it. Will last forever.

well a looked at the rotatio assembly fisrt but the prices are pretty high and i doon't have a very good income because of highschool and college not lettin me get much hours so a think ima have to take the cheap route but thanks for the advice

A stock cast BBC crank and OEM rods can withstand some big Hp, the key is getting a good spin job (internal balance) and using some good ARP rod bolts. Polishing the stock rods beams would be on my list of things to do as well.



NOTE: if you do go with an internal balance you'll have to use a neutral flywheel and balancer.


I had a friend of mine years ago that ran 5.80's in the 1/8 running a ron's toilet bowl injected 468 BBC.
Granted the car was light, only 2400lbs W/ driver.
But it still had all stock internals and a good balance job, I was impressed.
Not that I would go that far with stock internals but that's a pretty good testament of how strong those stock BBC bottem ends can be if prepped right.

Now if you can swing it, I'd upgrade the cast crank with a OEM steel piece, that is if you can still find one, if so it would still be cheaper than going with a all forged set-up and not as hard on the ole wallet.

Goodluck, Cp

Read this thread, all stock rotator except pistons.

ummmm dumb question and this just shows my age and experience but ron's toilet bowl injection?????

It is mechanical alcohol injection...The "toilet" is the part that controls the air...what you would think of as the carburator...but it isn't a carb it's just a throttle body
The fuel is injected into the port

I agree with cepex111. There are quite a few trucks that pull with us that have cast cranks, upgraded ARP rod bolts, and a good balance job that turning 6500+ rpm. A lot of engine builders do not like building truck pulling engines because the abuse we put them through.
