454 Chevy Big block

Post by Patrick66 on Sat Nov 07, 2015 3:51 pm

Will a 454 Chevy Big Block fit into 1969 G10 as easy as a 350?

On these vans, the only belt-drive accessory you should need is the alternator.....From about 68 on, most of the SBC and BBC engines had the alternator tucked high on the right side which should work perfectly in these vans...... Fabbing up linkage pieces for morse/teleflex 33c cables should be no problem.....Get rear gears in the 2.70 to 3.23 range and you should also get reasonable fuel mileage at modern freeway speeds.....

I'm more of a Mopar guy than a Chevy guy. That said, the BB itch is shared with all American gearheads. However, the modern LS motor has developed quite a following and reputation and it is similar in size to the small block.
Depending on how 'modern' you want to get with it, you can really have your cake (great HP and torque) and eat it too (manners and MPG). Look into how guys are swapping them into street rods, since they also tend to have packaging issues and many prefer carbs and simple ignition to the EFI and coil-on-plug. You might find it's better for the time/effort/money.

The whole "LS" thing is really catching on with lots of folks, but here's my issue with it......BBC' s, SBC's, 4.3 v-6's AND the 194/230/250/292 sixes are ALL part of the Chevrolet "family of interchangeability, while ALL the modern stuff (LS, Trailblazer six) IS NOT!
Basically, if you opt to install an LS, you will have to fab EVERYTHING that locates it in the vehicle..... Then there is the electronics that must be grafted in and made to work......I can assure you that you'll spend A TON more money installing an LS and making it work than if you were to install ANY old-school BBC or SBC...... You would have to save a HUGE amount of gas with the LS to ever recover the difference in cost between the two conversions and (of course) all simplicity is out the window with the LS..... Forget being able to fix anything by the side of the road!
If you STILL want a little better fuel mileage and fewer gas smells, both SBC and BBC were available for years with both TBI and port injection!

P.S. The 66 GMC in my avatar had a 396 in it.....

AZ Don, good points! Especially with gas prices so low right now.

A stroker small block is a handfull too!
It's a good time to pick an engine package, so many choices!

LS info I found doing a quick search

I am up against the same issue I have had Big Blocks in most all my van's and street rods over the years but with cooling and room issues I am doing something different with my early I for one am "Not" a computer guy so I will stay "Old School" with a carburetor years ago you wanted HP you needed a big block last one I bought was a GM Performance crate 454 with 425 HP roller cam steel crank for $4,900 it was nothing short of "Bad Ass" in my 2,400 lb 1941 Willys Coupe but lately some of these stroker small blocks are nothing to laugh about "Blue Print" makes a 383 420 HP for $3,799 with a 3 year 50k warr you cant build one for that much lighter and smaller than a big block but same horse power my club member Dennis (RV) has one in his White 67 Chevy 90 Heart Beat and it is "FAST" vicious fast everything will bolt in with no mods replacing my 307 V8 plus about 350 lbs lighter then our big block friend here is the 420 hp version I am going with the 430 hp one but this one will do anything you want they have all different set ups check them out...!!!...http://www.ebay.com/itm/BluePrint-383-Small-Block-Chevy-Crate-Engine-/131493818156?_trksid=p2141725.m3641.l6368

hey joe= in looking @ these engines- as I have built my own 383 in my van----- these all have cast ranks!!!= affraid you need to look into doing your own (costs!!) along with a rotating assm. - from SCAT or someone selling the scat assm's. on ebay!! I used a scat assm. that was premium riods & a forged crank.Forged pistons & in a complete set. Then I added the old skl. fulie heads!! yes alu are great -yet costs?? My heads - redone premium stuff= from a head guy complete - ready were 350.00!! Yes-takes a little time to build one but id guess i saved initially 2 grand!! installed !! That $$ can go into that 400R4 tranny!!, Paint or wherever needed!! cheers cheers cheers

Twin in the last few years we have had 2 machine shops close there doors in my area all we have left is "Titan " engines that said they will build me a 383 for 3k not including intake,,, flywheel or balancer plus being a performance/race motor only a 90 day warranty...!!!..they only have "Full" 3 year warr on stock motors no mods....Before I bought the GM Crate 454 I had a 1973 454 that needed to be rebuilt they told me $3,400 and if it had the cam I wanted they said "NO"warr ...I paid $3,900 for the GM crate 425hp motor 2 year 12,000 mile warr... 20 years ago you could cut the cost in half doing it your self by the time you spent $400,00 on a new carb $300,00 on a msd distributor add the cost of the balancer,, flex plate,, intake and machine shop charges you have way more than "Blue Print" charges with out the warr ...You can buy a "Stock" GM Crate 290 hp 350 for $1,800 3 year 50kwarr... NO machine shop can beat that price maby its different in other areas but I dont see duplicating the one I want all parts included and warr for under 4k..I envy the guys that can do it themselves I just dont have the equipment or ability it takes to do it cheaper or I would have done it years ago...!!!...If anyone can build me a 430 hp 383 and guarantee it for 50k all new parts PM me income tax time and we will talk IMO I just dont see it happening but again I may be wrong..!!!... Very Happy ..

I'm a little bit more budget minded.......I bought a 91 Olds wagon with a roller-cammed TBI 305, a rebuilt 700r4 and a 323 posi that I'm going to rob the drivetrain out of for my 69 van...... the car cost me $800!
I'm also going to get the lock solenoids, mirrors, HVAC, serpentine belt drive, power window motors, etc. as well as a lot of parts I can sell on the GM wagons forum.....
I've also been watching craigslist listings for 454 powered stuff for sale and have seen several late-90's 454 2wd rigs for sale under 2 grand... These would be port-injection with 4L80E transmissions.... These trucks/burbs would also yield a lot of good used parts to sell.....Most stuff built since the 80's is good for over 300k miles as long as you install a new timing set while it's out of a vehicle....
That BBC is settin about where I want mine to set back from the original location....
