stock 454 vs. TBI 355

[dyeager535]

Just FYI, LT-1 and LT1 are different engines. I don't think you mean LT1.

Nickel is used in the making of engine blocks, probably every one, there is no question.

That's like saying you can make coke because the ingredients are on the side of the can.

This one is real easy: Show me actual metal tests or GM documents (online is fine) that prove certain blocks are high nickel. No hearsay, no speculation, no "proof" other than actual data. No more posts regarding metal content/block superiority until you or anyone have either one. You can change my thinking, it's real easy: prove it. I've listened to far too many "experts" say things are this way or that, only to find that they are hopelessly wrong.

I'll go back to my Vortech heads now, and fill up my tranny with Dextron.

????? i don't get it....

I am not going to try to convince you or spend 3 hours looking for proof. Its not worth my time and its obvious no matter what i post you'll say its false or hearsay or question where info came from.

FYI, my dads old shop was 40 feet away from one of the top race engine shops in cali. B & B performance. The guy has forgotten more about motors than most of us will ever know. I think i'll take his word for it instead of arguing and asking him for gm sheets to prove it.

I learned about nickel content when i built my dirtbike motor. It is a known FACT that nickel wears slower and resists rust better. When the military came out with the AR-15 it had steel barrels and mechanisms. During vietnam thousands of soldiers died becuase their gun was jamming and rusting out. What did they do to fix it? NICKEL plate it. We have been using that same gun(now called the m-16) for about 30 years.

As for motors, I never said i heard this from so and so... i found out from doing research on blocks for my truck and cylinders for my bike. Yamaha and many other manufacturers will tell you themselves that the nickel cylinder will last longer then most any other cylinder on the market.

gm doesn't need to give info to prove it when dozens of other companies whether auto or non auto already have.

Like i already said, nascar nickel, and titanium plates just about everything in their motors. It's a well known fact those motors take more abuse then anybody thought possible. sustained 8k+ rpm for up to 600 miles. yeah they get rebuilt after every race but pull the nickel and titanium plated parts out and see how long they last.

I really don't want to get into this, but DW you are soooooo wrong about the M16. As a former armorer during the 70's and 80's, I KNOW why the changes were made to the M16, and I have NEVER seen an M16 with nickel plated parts. The fix for the M16 jamming was the forward assist lever and getting the grunts to clean their weapons more often and not leave such a heavy coat of oil inside the chamber of the weapon. The Russians used chrome plating inside the barrels of some of their weapons so they did not have to clean as often. Maybe that is what you are thinking of. I am not telling you stuff I read somewhere, but what I personally experienced, so don't even start telling me I'm wrong, cause you weren't even born yet boy.

 

[dirtwarrior17]

your are definetly right about the forward assist..... i said it wrong. From what i remember of the history channel they nickel plated the chamber, not the mechanisms.

Regarding nickel content in blocks - I've read in many magazines comments about some motors having higher nickel content vs others. I've also read this in performance books regarding raceing and engine rebuilding. True or not true, I guess this is where the majority of us get this informantion.

hmmmm,

well I have had the pleasure of going from a small block to a big block, I have also gon from a big block to a small block...

everytime the big block is what gets my vote

big blocks are always fun!

with a big block in the 75 it MURDERED tires, now I am putting a happy big block in my 2wd project, the truck originally had a inline six with a 3 speed so this might be a change in the way it will feel?

 

[diesel4me]

You might....

Yeah,you MIGHT notice a slight increase in acceleration! ..along with increased tire wear,parts breakage,speeding tickets,and an increase in the size of that silly grin on your face!

I saw a bumper sticker on a Chevelle SS yesterday--"Big Blocks Give Me A Woodie"....

Thanks for all the replies. I am doing the only thing any respectable wheeler would do in my situation.....fuel injecting the big block. I would also like to thank Mark over at Affordable Fuel Injection for making a great product that is able to grow with my needs. Now if I can just get my tranny to work.

I would like some advice from guys that have been there. I have a 355, flat tops, and the top end off a 91 TBI 350. I just got done doing the TBI conversion and took it out to the mudbogs and sucked water into the engine. Now it makes a really good misqito fogger. I was going to just hone and re-ring it, but a friend offered to give me a 454 that needs to be gone over.
So my question I guess is would I be better off with a fuel injected 355 or a carbed 454? And then in the future could my wiring harness from Affodable Fuel injection be made to work on a 454?

Yes the harness will be fine. You will need a new chip and the big block TBI unit too.

D'oh!

I didn't read the entire thread, just replied to your first post... thanks for the vote of confidence.
