L-29 454 vortec

anyone seen any dyno pulls with different cams in this motor with these heads.  i picked up this motor large oval vortec with roller cam and i'm trying to find out if this motor will make good hp numbers. this motor will go into a 72 chevelle. looking to get atleast 400 hp or pretty close to it. other wise i might empty my bank and put or some high compresion edelbrock heads. let me know if you know of any build ups thanks  

a good intake ,carb and headers and your there.  

no disrespect or anything but just wondering how you know?  have you had one with vortec heads or do you know some that does or have you read it some where? thanks for your help  

It's a 454, good power is no problem! I think from the factory that motor made 290 HP. That's with the weak factory roller cam. Those are good heads, so they'll breath pretty well for the street and make lots of bottom end power. Factory compression should be 9:1

I good roller cam running about .500" lift with the right intake and carb, a set of roller rockers, good springs, and you should make 400 HP easy.

To see how much cam your engine will take, you need to see how much valve travel you have before the bottom of the retainer hits the valve guide.  

thanks for the reply

great product and you build the engine on computer before you waste your money chasing comments and what others have to say. and than you get the exact part numbers from the product you use to build the engine with, when you are done you have the engine you want, without a waste of you hard earned money,
hope this helps

I already have a chevelle 1972 with this L-29 454 fuel injection installed. Iam trying as  you do, to increase the hp on this engine. just let me know if you find an alternative. thanks Felix              email: fgashelby@gmail.com  

The best thing is a bigger cam. Since the factory cam is so mild, a basic cam swap will probably get you 50 HP right out of the box.
