A Body V8 Swap question

“Carburetor” not “carborater”

While not an answer to any of your questions, is there a reason you want to swap out the slant six instead of just "hot rodding" your existing motor to get the performance you want? You said it's going to be a relatively mild motor anyway, and a hot slant is more unique than "just another small block" anyway... and it saves you from all the associated swap hassles and parts hunting.
A modded slanty is always an attention-getter at the shows, and the satisfaction of blowing off the Brand Xs with a six is always great.
Plus you'll be able to afford to drive the slanty a lot more often.
I agree to that. I have a few reasons but I have thought about it and actually done some modifications.

I also have a 1960 Dodge Dart Seneca with a slant 6 is really good shape. So I have 2 slant 6s.

With that i have started to modify the 65s slant some. I ordered the TTI exhaust system for it, I will probably order the AussieSpeed long runner intake for it and a Holley 2 barrel carburetor to pep it up.
The reason behind that is in can always take it our of my 65 and put it in my 60. Even do some head work while swapping it.

I am noticing quickly that for the price of slant 6 exhaust ($600 shipped), the AussieSpeed intake ( $600 ish shipped ), a Holley 2 barrel carburetor ($550 ish shipped) , a performance ignition ($350 ish) shipped has me at around $2100 and make what 160HP .

OR I can buy a used 318- 360ci for $350-$500ish, a 904 trans for $200.. that's $700 and use the remaining $1400 ish for upgrades and make 250 plus wheel HP.

Yes i could turbo the slant or super charge it. But a supercharger kit is $4k plus shipped.

I could turbo it for a few thousand (turbo, piping, fuel management, turbo oiling pluming etc... but it would still get me around the same hp as a reliable mild 360, maybe less.

It would definitely have the cool factor, but that's where my 1960 would come in when I pulled the slant out of the 65.

At this point I'm asking all these questions from you all to see just how much time, effort and money it would take to do each idea.

I do agree, built slants are very cool
