small block motor mounts?

[tfinley]

I am working on a 1972 duster. The car came with the original 340. I am wanting to use a 1966 318 just to keep the car mobile while doing the restoration. I took the motor mounts off of the 340 and put them on the 318 but now there is not enough room for the fan. Everything is to close and suggestions?

Do you mean poly or La 318?

Um, yeah- LA318s didn't debut until '68. It may have come out of a '66, but it ain't original.
Pics, pics, pics...

340 and 318 mounts are different. DONT lose the 340 mounts. $$$. Buy a set of 318.mounts for like $40??
@RAT ROD AL may have some.

66 318 could be a 273. Everything from any LA should bolt right up except the right (passenger) motor mount installation wise. Does it have rectangular valve covers or are they sawtooth? These are 318 poly, mount fitment unknown on a poly.

The valve covers look like LA covers to me, i will get some pictures tomorrow.

This may not help but the mounts go on the backside of the engine lugs.

What kind of fan? Clutch? Flex on an aluminum spacer? Those can be changed....

If ya cant use 318 mounts on a 340, makes sense to me the same applies for 340 on 318 wouldnt it?

Many, many years ago I had issues with a motor mount not fitting on a 318 It was from my 360 lol. Grrr. Whoever got that car, got a bonus.

The 72 motor will have the alum water pump (long).
The early motor will have cast iron pump (short).

Is the transmission bolted to its mount? Kim

Post #12, that engine should be 3/4" shorter than the 340..
