but just imagine all the work you put into shorties.. what you would gain from L/T's.. L/T's are definitely worth it.. if you are gonna do ANY headers... i have had shorties on a cobra and L/T's on my current car and i will never do the work for shorties again, just not worth it AT ALLEdward Clark said:Don't undersell the shorties on a blown motor. I did two mods at once so I can't really tell exact numbers but I gained over 50 rwhp by just adding 2 pounds of boost and JBA shorties on my car. I kept timing the same and richened the mixture from 12.0:1 to 11.5:1. That's not all from boost.
So while LTs are somewhat better performing there may still be reasons to consider shorties.
