OT:Chev 1T engine swap Question Y-Block Truck engi

Benny,

I love Big blocks can you tell by the pic?

You will have to get big block motor mounts, roughly an 1" shorter. You can use the small block moutns, the motor will just sit a little higher.

Tall decks, commonly called truck blocks (not from a truck, but a 366 or 427) have a 0.400" taller deck height, pistons are unique with an extra ring. And of course, its the nice super strong 4 bolt block. The have tiny intake runners, which are great for low end torque that you are after. Bad for us hi-rev drag racers.

About the only things that are not shared with the common passenger car big block are the intake and the distributor.

These motors use to be quite the find for us drag racers. You could sell the crank to buy a stroker crank and have quite a motor just had to scrap those "peanut port" heads. They are not as common anymore.

Oh your gas mileage question...
Worse than the small block empty, better than the small block with a load since it won't lug the engine as hard.

Keep a gas station in site!!!!!

Does your 427 take 8 quarts or 10? I assume it uses the 2-quart filter?

Allan

Look at the forward slope of the pan to be sure it will clear your front A-frame crossmember.

Like Mike M reminded us, GM made many different configurations of that oil pan, depending on a wide range of applications and they could vary all the way from the 5 quart to the 10 quart sizes.

And that comment about a big block not having any snort ? I'll take the big block for pulling a trailer any day over a small block.

And if that 427 will fit ? I can't say for sure. I have heard they are taller and the oil pan looks bigger ?

The reason Iam considering it is because I want to pull a B-hoe on a trailer.

The 350 will do a great heavy load even at road speeds but if really heavy at or near 20000 combo, grinds up the steep or long hills. Which there are many here, even on the Freeways.

I license this truck for a trailer combo weight of 22000GVW

All those old Chevies will interchange. You'll need just about every bracket, bolt and nut from the 427 application to do it tho.

I've had something like 7 engines in my old '78 from the 350 to the Olds diesel to the 454 and 400. I've ran it on gasoline, propane and the diesel.

Mine is a 4X4 too, so that 2-wheeler ought to be a snap.

Allan

Best of the bunch was that little 400 small block. The big blocks never did impress me. Just don't have the snort.

Allan

I had to use the extra spring out of a Sub to make a 3-leaf on my 4X4. Don't know on your coils; try it and see, I guess. If worse comes to worse, you could probably use springs out of a 454 tonner.

Can't speak to the 5-speed change, as I've never done that one. That sucker is heavy tho. :>)

Allan

Now to make the trany even heaver I have to keep the PTO with the big Hyd pump alive that has 3 hyd valves installed! woe!
