454 vs 350 in my truck - The 1947 - Present Chevrolet & GMC Truck Message Board Network

onetoncrewcab · 05-02-2003, 09:26 PM

Hey All,
I have a 1970 Chevy pickup that I'm in the process of putting disk brakes in. I'm also putting the whole drive train from a 1985 Chevy Suburban into the truck. The Sub has a rebuilt 350 small block. I also have a rebuilt 454 in a 1982 Chev CrewCab 4x4 that I am thinking about parting out. I have a post on the 73-87 board about this. Hmmm...which engine should I use if I part out the crewcab???
The 350? The 454??

Decisions decisions.
Opinions? (there should not be a lack of THAT on this board!) LOL
Thanks
Mike
PS...If I don't part the crewcab, that will take care of my problem.

No ?, put the big block in that half ton, you won't regret it!

**kwmech** · 05-02-2003, 09:47 PM

I wouldn't hesitate to install the big block, lots of fun

onetoncrewcab · 05-02-2003, 10:21 PM

Thanks! So far you all (well...both of you) are leaning the way that I have been thinking.

if i had access to a big block that i already owned, i'd slap it in there as quick as i could

onetoncrewcab · 05-02-2003, 10:23 PM

Oh yeah...the 454 is going to be hooked up to a 700R4 tranny. Any problems with that combination?

Hmm whats happening with the front diff and whatever tranny and transfer case combo from the 82? I'm looking for a front diff from a 1 ton. Rod

onetoncrewcab · 05-02-2003, 11:03 PM

Hi Rod,
The one ton has a 3/4 ton differential up front. It is not the correct one for the truck.

Mike

Rod · 05-02-2003, 11:15 PM

You sure... does it have a 60 or a 44 or something else cast into the webbing at the lower right corner of the diff pumpkin housing facing forward. Rod

" There is no replacement for displacement " go with the 454

Iron-Butt · 05-03-2003, 02:44 AM

i would go with the 454.

lngbed71 · 05-03-2003, 10:30 AM

With a big block, you could do something like this.........and have much much more fun.

casey · 05-03-2003, 11:27 AM

keepim both, try the bb if the gas kills you switch

gr8scott51 · 05-03-2003, 11:39 AM

It's like p$n*s envy - everybody wants a bigger one. That being said - which engine is stronger? How much money do you want to spend? I'd love a blown big block, but it isn't in my budget. Good luck, Scott

gr8scott51 · 05-03-2003, 11:44 AM

Oh yeah, the tranny question.... Depends on how you drive, but that 700R4 won't take too much abuse. Better with a 400. Have you been watching the Copperhead project on "Trucks"? They beefed up a 400 and added an overdrive unit to take the power from the new 572. I suppose ther are a lot of 454/700R4 combinations on the road though.
