I have a GenIII LS/LM7 5.3 motor which is probably the most popular chevy small block for cheap power right now. They are making outrageous power in stock form because they have a bullet proof bottom end with 6 bolt mains.

The motor has great alloy heads making it lighter and more compact than the 350. Takes any GM trans.

These motors are being fit into every vehicle imaginable with ease, and probably the Mustang swap is the most popular for drag strip duty.

Have a look on ls1tech.com for all the information on these motors and how to run them with injection or carb easily.

The one I have is a 2001 it is in great condition and needs nothing. It comes throttle body to cast alloy pan including coils and exhaust manifolds (no alternator or starter).

Best "bang for buck" motor you can buy £800.00.

Same design, but that car uses the 5.7 Alloy block motor worth several thousand more than I'm asking for my 5.3 iron block motor :) The iron block weighs about 30kgs more (nothing really) but is much stronger and can be bored out to 376 ci.
