Hey guys been reading posts for a loooong time on here now. Got lots of info I needed for starting my swap and the community seem fairly nice! I have a question though that I cannot find an answer to and it is probably very stupid. I’ve found a ly5 motor with low km locally on craigslist. It is a long block, iron block motor... I cannot find anything regarding if a long block will fit, or if it is any harder to do than a small block engine. I was hoping to find a LC9 Engine as they are aluminum and small block. Unfortunately wreckers around here have 0 Gen 4 engines... Only reason I am looking to use a Gen 4 is because i read on current performance that they make for a much nicer (compatibility wise eg. Throttle pedal) swap, and my truck does have an E67 ECU I plan to flash as a 09 V8 colorado and have VATS + Rear O2’s + shift points removed (Truck has ar5 5-speed My question is has anyone used a Iron longblock LY5. Is it doable, or should I wait longer for a more suitable engine. ANY help or recommendations is greatly appreciated. Thanks! Oh and the truck is a 2WD SLE No torsion bars if anyone was worrying about weight being a factor but i don’t think it would be?
