The Stovebolt Site Forums The Parking Lot Big Bolts Chevy 350 in the big bolt?

I just talked to a guy at Advanced Adaptors and he said the 350 will bolt right up to an SM420 without any adaptor needed replacing my babbit engine. Is this true because it seems too simple. What other modification will I need to do besides engine mounts and exhaust/steering clearances? I need help quick so I can find or order a new engine to get the truck working again. Thanks!

I would think I'd want to upgrade the transmission of I'm already upgrading to a small block. I was thinking like a turbo 400 maybe...
But I'm still new to all this.

What you will need is a bell housing from a '55 snd-'66 v-8.excluding '60-62 with hydraulic clutch. The 350 will not bolt up to the 6 cylinder bell housing. The sm420 will bolt up fine to the v-8, it was an option until '67.

As others have said you can bolt the 350 to a bellhousing that will bolt to the SM420. The original bellhousing will not fit the motor. The trick is you need to bolt that bellhousing to your frame.

Either you need to change the crossmember or make adapters to mount the bellhousing to the exisitng crossmember.

This is a doable project but it does require some work and maybe fabrication. I've seen it done very neatly, almost stock looking, and I've seen it cobbled together looking dangerous to drive or ride in.

i've been looking at this myself. i have a 51 with a 327 cobbled into it, with REALLY shadetree front engine mounts. using the transmission, bellhousing, which has motor mounts on it, does anyone know who might make front engine mounts to drop a smallblock 400 into a 1 1/2 ton?

1. Will the Jim Carter,Chevy Duty or LMC v8 engine mount kit work in the big bolts (1.5 ton)?

2. Is the SM420 strong eneough for the 300HP 350 or should I upgrade the trans (i wanna keep the 4speed and PTO).

Thanks again!

i would like to use the original trans. p.t.o. etc., with the 327 bellhousing. the bellhousing has the rear engine mounts, and the tranny bolts to the bellhousing, with no mounts to it.

back to the question, does anyone make a set of engine mounts for a v-8 into a 1 1/2 ton truck?

Use the aftermarket side mount set-up and you'll be fine. I made my own back before I knew about the aftermarket stuff and it pretty much looks just like them. I used a bellhousing from a mid 70's V-8 truck and made an adapter mount to connect it to the crossmember, that way I could use the SM420 without reworking the driveshafts,

If you look at the links in my signature line, the 48 4400 with the plow on is the one that has the 350 in it for about 8-9 years now.

I have a 1953 6500. I have a 1987 TBI 350 bolted to a 1965 bell housing, out of a c10 2wd. Then that is bolted to the original sm420. It worked great and I didn't even need to modify anything. I went to a junkyard and got a crossmember out of another c10 2wd. The whole combination is great!, now I am ready to bolt it in, so let me know if you have a questions or advice...

N. Phillips,

I have a question. This has been asked many times before...how did you address the steering box/exhaust manifold clearance issue?


Stuart

He hasn't yet if I'm reading it correctly. The engines not in the truck yet if I'm not mistaken,

Scott,

You are correct...I start asking before I finish reading!

My dad put a 283 in a AD 1 ton once. He put a u joint in the steering column and moved the box over. Then he bent the drag link so it moved in original line of travel. Had to have a front cross member, 350 water pump, had to move brake pedal over an inch or so, had to hide the push button somewhere under the dash to activate the starter. He had it so sitting in the truck, or standing next to it, you'd think it had the stock six in it.

Koolkar;
You could use the front mount from a 60-62 V-8 powered chevy truck. You might need to grab the mounting perch off the front crossmember and attach it to your crossmember,or you might be able to just drill the two holes into your crossmember to fit the stock '62 mount. (haven't measured it all out,just an uneducated guess.) Speed
