Hey guys, I am trying to choose which size motor to put in my mustang. I have a 390, and 2 302s. Anyone know the weights of these engines (they're both 60's motors). Provided I have the right rear and tires-is it possible to bring the front end off the ground with a built 390? Thanx guys~

The 302 is about 300lbs lighter, then the fe with aluminum head and intake. That said yes a built 390 can lift some tires if built right. But so can a 302.
For what you want there is no replacement for displacement. And in the end either will cost major $$$$ to $$$$$ digits in cash.
Easier to get more power already being bigger and tuned right it all out fly's.
What are the true goals of the car?
Date 1969-- To all out fly you will want cubic inches and for what it is worth a 390 gt motor,( 427 and 428 warmed up did even better) in a 69 stang could induce a tire lift might not have been a funny car style but the nose was known to go skyward.
Forward today-- Parts are more expensive and gas is not of the same quality but power can be built from yesterday's motor's to work with todays standards. Look into forged piston's, aluminum heads and intake intake dual pattern cam, and stiff spings running 11:1 max (though some are getting 12.5:1 to work on premium fuel and power will come

What was in the car before? If it was a small block stay with it, they can be beefed up for plenty of HP. If you go the FE Block 390 and there was only a small block originally, you will have to beef up the front end suspension. The small block will give better handling, weight distribution and won't be so nose heavy. Guess the choice is yours, but get all the input you can. Still nice to have that FE block for the torque.
