thumper heads?

sweet yo, while its apart why not put in mustang notched pistons and some AFR 180's on there and make 400hp :evil:

The ported E7s he has are capable of 400 HP at the flywheel with the right stuff.

How can you get 400hp? with like ported intakes and a 600 lift cam?

An E cam should do it. It takes a lot of other parts and gets expensive using FI .... cheeper to go with a carb or a good CFI aftermarket system.

Could E6 heads be ported to flow similar numbers?

Yes the ports are basicly the same we run the same CNC program on them. The combustion chamber shape is the down fall of those heads. They might work well on a low boost application because of the fast burn rate. We have done a couple sets but ass with most no feed back.

Hell, I would do an E cam, ported heads, and a full carb conversion if it got me 400hp!!!! Why is it easier to make power with carb? I thought fuel injection was more precise and such. But wouldn't an E cam push the limits of my flat top pistons I wonder, maybe not with 1.6 roller rockers

Heres the thing cams dont give you more air flow well a bit. Cams mostly change the RPM band were max power is acheeved at some point at a loss of low end. Air flow and air speed is were HP is ported heads give massive air flow increases. If the port size is properly matched to engine ssize and usage not much of a cam is needed and peek power is reached at a lower rpm with often increases in low rpm power. Low duration @ .050 lift to and lesser over lap cams more efectivly fill the cylinder high over lap cams blow power out the exhaust valve trying to more mixture in the cylinder so you have to rev the engine higher and loose low end torq. Hight lift cams compaired to duration are now desireable. There is a bunch more to all this but with our heavy cars .5 ish lift and 220 duration is a good pick.

The carb thing is just easyier and cheeper. With out spending big bucks carb could net 400 HP. You dont need dual quads it is ann experment for me in high air speed to gain a flatter torq curve single quad with good intake will work. Figured before doing dual quad motor an FI set up using 39 Psi system pressure to support 400 HP would run around 4000.00.
