So I'm ready to mount my 1954 235 truck engine into my '46 pickup. My question is about the four front mounting carrage bolts. Are they normal (Ace) grade mounting bolts or something stronger. My understanding of carrage bolts is there normally used with wood applications, not holding a engine in place. What were the OEM sizes of the bolts? As allways thank you in advance for the advice.

Metricnut -

Hopefully you followed the "swap made in heaven" directions from Patricks and exchanged the mounting plate with the original. My 216 had square holes (is this an oxymoron?) in the bottom of the plate while the newer '57 plate had no holes at all.

I suspect that the carrage bolts where just another securing safety to help prevent the nuts from vibrating off, or if they did to hopefully help hold the bolts in place until you discovered the missing nuts.

You may have already realized that the starboard side bolt must be installed prior to installing the front mounting bracket.

I just took a look in my Master Parts List and it only lists the bracket and bolts as one assembly.

Good luck

My temporary motor, a 235, came out of a 54 BelAir, no holes either. I just put it in with the bell housing, bolted the back end up, lined it up, and drilled out the bracket from the under side. Worked fine.

Thanks for the replies everyone. I have the correct square holed bracket but am leary of using standard carrage bolts. Can someone please advise me on how the bolts should be tightned? Are both mounted firmly?

I used ACE carriage bolts when I mounted a 54 235 in my 40 last summer. While my brother pushed down so the square holes (not an oxymoron) caught the carriage head I tighted from below. I didn't use a torque wrench so I couldn't tell you how tight.

Most of the weight is resting on the frame so the bolts don't carry much load. If you flip your truck then it might be a problem, but then you'll have other worries.

I beg your pardon InMy40s - A square hole is something like a jumbo shrimp... just kidding. Here is an adjusting proceedure from a Japanese manual as best as I can recall...

"When adjusting rockvolt turn rightwise until likewise, otherwise while turning leftwise until rockwasher is there"

If that doesn't work I always tighten the first bolt until it breaks and then tighten the rest just a tad less.

If you don't care for the previous instructions InMy40s suggestions sound pretty rightwise to me.

Hope this helps.

MetricNut,

I bet if you give Patrick's a call they can give you the info you need; they won't mind your call either. Great bunch of Bolter's there.

What a great site! I'm sure that your finished truck will rate right up there with Snook's. BTW, do you recall how much bait Snook used to catch the '41?

If I remember correctly, the last ebay auction was over 28 but it had not hit the reserve. From talking with them at Snooks, I think they might have been the high bidder but they never did really tell me. The deal was made outside of e-bay and they mentioned the seller was trying to get everything he invested into the truck back which we all know rarely happens unless you have a muscle car at Barrett Jackson.

p.s. thanks for the comment on my web page...glad you enjoyed.
