Got a 348 for my 61
 

So I just got a 348 with a tri-power intake for my 61 step side and I'm just wondering if there's anything important I should know about these engines before I get started with the rebuild.If anyone knows of any good books or websites about these it would be a big help.

I stuffed a 409 into my truck at one time and for clearance I had to nudge the firewall on the passenger side to be able to remove the valve cover. I used a hydraulic spreader.

I can't help with the subject, but I will say I hope you post up lots of pictures!

Awesome! I would love to put a W motor in my 64. Congratulations!

Well I'm reviving this old thread because I finally got this engine set into this truck and there are some problems.:lol:

The big one is that using the stock mounts for the bell housing/transmission I can't get the left cylinder head on. It hits the firewall before the rear dowel pin lines up.

We are thinking about making a custom spacer set to move the engine forward but leave the bell where it belongs. This would be a 2 part set. One spacer for between the block and bell and one for between the crank and flywheel.

What do you guys think?

My 2 cents worth..
either modify firewall or move engine mounts forward
Not saying spacers wont work, but it sure won't be ideal....how thick of spacer are you talking?

Re: Got a 348 for my 61
 

Unbolt engine and trans from mounts, tilt, install head, tilt back and see what hits. Fix that, bolt it down.

Re: Got a 348 for my 61
 

Well it looks like I won't need a spacer after all.
I figured out that I can get both valve covers on. The right one is not easy but it does fit.
As for the left head hitting the firewall, I forgot that I haven't got the new cab support bushings installed yet so we'll see what it looks like after I do that.
