Thread: cam and heads

THose heads will not do it,the vortecs flow more than they do,only a small amount ,but there half the price.. and the vortecs are good to about 400 hp with a very good tune and bowl work.What are you going to use the car for ,track,street ,daily driver ?I would use the vortecs a rpm airgap and a XE 268 comp cam.a little under 400 ,but it will make lots of torque ,what a heavy car needs to get movin.That cam you showed will not make much torque or hp untill the rpm starts getting pretty high 4500-5000 before the hp would climb above the vortecs,not good for the street, Race track only the team g and big cam might do a little better in the 1/4 ,but not by very much.Usually not many times you can rev to 4000 on the trans brake at the stop light either.The vortecs need new valve springs and some minor work to make them handle a cam with a lift that much over .460

If you can buy Vortec heads for half the price of the World products I will take 20 sets.
The point I am try to make is I can buy the Dart Iron eagle heads or the Pro Topline heads or World products for around $600 to $635.
Both the Dart and the world heads are better heads overall.
They have thicker decks and come with valve springs good to .510 lift.
The vortec heads are thinner castings and more prone to cracks.
All you have to do is pick a set up and you will tell the difference.

thanks guys for all the help i think i under stand a lot more now also the reason i was goin to go for the world heads is that i can getem real cheap 450 in the boxs
