Hey guys,
I'm doing the 4.3l to 350 swap in my boat, and am wondering how far forward I need to move the forward engine mounts, I thought it was 4 1/2, but am not really sure, any input?

Could it be that since both blocks have the same archetecture, that they are in the same place? Wouldn't that be fortunate!
I know on my 5.7 the mounts are pretty far aft.

Well, I measured it, come up with 4 1/2" difference 9 11/16 and 14 3/16
Oh well, Hi ho Hi ho, out the drill goes

You know, you think I would have written it down, it was 9 13/16 and 14 3/16 from the aft end of the block to CL of the holes, so a difference of 4 3/8
Drill came out, holes got drilled, through the glass into the wood, and guess what? well, stringers are GOOD!!!
Anyway (should have checked that BEFORE I spent the money I did on the engine), I drilled, relocated mounts, sealed all holes, etc. Dropped motor into boat on Tuesday, alignment to my measured location was OK. (PHEW!!)
