No big block I have the bottom end already just looking for help with top end stuff. I have a set of camel hump 202 but don't think It will give me what I want out of them. I really don't want to spend $1500 on some heads I was looking more in the ball park of $1000-$1200. But I guess I need to just break down and spend the money. Just thinking that the $200-$400 could be used on some more engine parts like cam intake carb.

IT actually has kb pistons. I was looking at some pro filers. Most info I found is looking good. Plus they are in my budget. (around $1100) They are 210 cc. No I will probably never dyno the engine. I just dont want to waste my hard earned $$ on something Im not going to be happy with

In a traditional 184346572, you have three same crank BTB pin fireing
(4-3, 6-5, 2-1)
In a 4/7 swap 18736542 you only have two (8-7, 6-5)
In a double 7/4 - 2/3 you go back to three same pin BTB fireing.
Are the double swaps proven to be any better?

I think the LS motor have the double swap, it improves cooling and the harmonics are less. If i recall Warren Johnson was messing the swaps to improve the cooling on his prostock vehicles, there's supposed to be some HP advantage due to the cooler running of the cylinders and for sure the less harmonics will help the engine last longer. I've never ran a 4/7 swap cam but i do have one in my 434" motor that's going in my Malibu.
