302 Ford or 305 Chevy?? That is the question

Hey everyone how are you all doin. Im posting this thread to Firstly say Hello to everyone on the site as i have just registered and Also to try to find some direction as to where to start with my Jeep build up. I have just bought a 95 Jeep Wrangler YJ. The body is in pretty good shape and shouldnt need any work as of right now, later down the road im sure ill do some body work on the Jeep but for now its not a pressing issue. The real issue is im wondering which way to go in the Engine department. The Jeep only has a 4 cylinder AMC engine. Im wondering which engine would be a good choice for a V8 either the 302 Ford or the 305 Chevy engine. So if anyone has any input as to which engine i should chose then please give me some feedback. All feedback is appreciated and welcome.
Thank You

Depending upon the year of the motor, I would avoid the Chevy 305. I had a 78 Malibu and the 305 in that era were known for soft cam shafts.

302 or 350, No to the 305. Then decide if you want more torque or rpms. Personally ide go with a chevy 350.

i say 350, way more common and parts are easier to find for the swap.

personally i would at least keep it in the family and due a 360 or 318. i'm just not a fan of chevy and ford in jeeps.

I would use a 4.3 V6 and forget about the V8, better milage and better torque to weight ratio. I put one in my CJ7 and it had plenty of power, I was even running 38.5's with 4:10 gears no problem.

If you use the TBI setup you can find parts in any junkyard if you needed to and the wiring is much easier than a vortec. Remember almost every s10 and astro van had 4.3's in them you should be able to find a good used motor for around 200 to 250. Your jeep will like you alot better for it to as your suspension will last alot longer

LS7 crate motor, but you may end up doing wheelies down the road.

I say neither of those dinosaurs. Get a modern GM V8 from a 1999 and up full size. Call your local wrecker. Stuff in NF is normally more expensive than here in ON but you should be able to get everything (engine, transmission, transfer case, electronics) for ~$2k.

The cool thing about the Gen III GM V8 engines is they are lighter than the original 6cyl (even the iron block truck engines) and almost as small as a 4.3 V6 in length and width. You can get a 4.8L if you want something small, but the 5.3L is probably the most common Gen III in junkyards and way cheaper than a 5.7L LS1.

The Gen I GM 350 v8 is probably the easiest and cheapest to swap in though.

I love my Fords, but pick up a parts catalog and compare the prices of Ford parts vs GM parts. You can buy a brand new GM Parts 350 crate motor for about 2k. You can't touch a Ford 302 or 351 for anywhere near that.
