Okay, if we're going to waste bandwidth on discussing a 4 cylinder swap, how about something that makes sense, even if it is evil! LS1/2/6/7 swap into a 65 2+2. I have never owned a GM product until I bought my GTO last spring. The LS2 engine is truly amazing with aluminum block & heads, ~350 RWHP out of the box, and LIGHTER than an iron SBF...and WORLDS lighter than a modular motor. For example, there are sub-400lb carb crate LS1 engines. The stock heads are on-par with mid-range aftermarket Ford heads. This is really the most sophisticated pushrod V8 in existence. The LS1 swaps are becoming very popular in 1st gen Camaros and Firebirds. Now, don't get me wrong: it is VERY HARD to really consider this...but, the ability to build a very fast car with a lighter engine is intriguing. I considered doing a modular motor in my '66, but once I found out how big and heavy they are [as well as expensive to modify] I decided that was a no-go. In that car, the Kenne Bell blower will weigh less than the iron heads that have been replaced w/ AFR's. Okay...if I am not permanently banned for this, has anyone actually heard of this being done? And please spare me your anti-GM flames. I have owned a gazillion Ford products and have ALWAYS like Mustangs [well, only since the fall of '65 when my dad bought his]. As I posted elsewhere, when I looked at a 2005 GTO vs a 2005 Mustang for the same out of the door price, there was no comparison...The LS2 + the Australian Holden car is sweet. So...thoughts?
