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.

Good cylinder heads are what make the power. If your never going to dyno the engine, then buy what is in your price range. I'm assuming your using one of eagle's budget performance kits with speed pro pistons ?

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

i have a 388 sbc with ik200 brodix heads and solid roller cam and 13.1 comp and it made 600 hp at the flywheel.hopes this helps

please discuss... :wink:

my motor is like guy aboves, 385
010 block, block filled to water pump,13.2to1 compression
all 4340 rotating stuff
210 cnc afr heads, T&d shaft rockers
crower custom built for my motor 4/7,2/3 swap cam, big roller
super victor intake, pro system 4150 carb
Its over 600, and it runs :D

I've heard a few other guys talk about a 2/3 swap on big blocks. I run a 4/7 swap which has been around for a long time, but wondering about a 4/7 2/3 swap cam when I freshen it up.

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.

Zip.

My cam is custom ground for my motor, and it runs damn nice!!!!!!
