wow I didn't realize just how much room is in there,also looks like the transmission could stand to be shoved back a good 3-4 inches.

lol I guess you haven't seen my engine bay

just took a peek, looks good. the engine bay lights are a pretty cool touch.
also ,is it me or is the 3.8 wider than a 5.0? I know for sure the intake is wider but what about the block itself?
Yeah I've got a running engine in there and still have enough room that I can literally stand up in there and work. (not while its running though lol). As for the lights, I changed those and went with LED strips, looks much better now... Well, not now, as I haven't swapped the setup over to my TC hood yet, but anyway....
I don't know about the 3.8 being wider... I suppose it is possible, if the compression chambers are set at a greater V angle than the 5.0
The 3.8 is wider. It has a taller deck height than the 5.0, but a shorter one than the 351W. I seem to remember reading somewhere that the deck height is closer to that of a Cleveland, somewhere around 9.2" compared to the 302's ~8.2 and the 351W's ~9.5
makes sense.... the engine is huge for a v6
yup, that's what I was thinking when I was looking at the difference,so a 351 should fit just fine.. not that im thinking of a 351, im sticking to my guns on the 5.0 swap. that should give a lil more side to side clearance which I am looking forward to!
Certain years of 351Ws (earlier blocks I believe) also had the 9.2" deck height, You can still get the blocks in either deck height.
The split port intake is even worse. Maybe an inch of space between the firewall, but a large wiring harness takes up that space, so it's as far back as you can go without crushing the wires.
I am surprised nobody mentioned how filthy my engine bay is!!! lol, the guy I bought the car told me that he actually was using it for a farm vehicle. the interior had hay,dirt,and other things that I don't even want to know.
I ws referring to the amount of room between the rad and accessories lol
