LOL I was just thinking if you choose a year lets take 1985
SUVs are blazer bronco and ramcharger.
available engines
blazer=I6, 305, 350
bronco=I6, 302, 351
Ram= 318, 360
all have available manual trans or auttomatic.
Now lets just say you have a base model with the small engine, manual trans and you want to swap to the biggest engine. Which vehicle do you want to do this to?
I mean a I6 chevy to a 350 swap is easy in comparison to a bronco or ramcharger. Hell you can even reuse the flywheel, motor mounts bellhousing, fuel pump, radiator ect.
A ford your going to need to replace all of that, AND your probably going to need "Ford special tools"
The dodge you will need to replace half that stuff.
Lets not even get into vaccume lines on a 85 ford or ramcharger simply rediculous amount of spagetti under the hood.
Yes they all have their flaws, but heres my story.
My first truck (before I was even 16) was a 1975 ford F250 highboy with a 79 f150 body and a 1968 390 police interceptor and a C6 out of a 68 galaxy. It was a hot rodded engine and had a real problem cracking exhaust manifolds. I went through about 6 sets before I found a set that fit.
My first legitimate truck (after I was 16) was a 1969 c10 with a I6. we pulled the I6 out and got a 350 out of a 78 and reused the flywheel motor mounts fuel pump bellhousing throttle linkages it all wired in right everything worked.
I later swapped in power steering pump, engine brackets, hoses and steering box from a 1987 2wd gmc, and again everything bolted in and worked perfectly. In fact that went so well I went right back to the 87 in the junk yard and pulled the front disk hubs, proprtioning valve, brake lines, brake booster and master cyl and swapped those all onto my 69 replacing the juice drums. Try that with a ford. (however I will note putting power disk brakes on it, made me have a 6 lug rear and a 5 lug front)
This is why I am a GM guy!
