engine woes

[silver00v6camaro]

ok im going crazy depending on what path i should take. As we all know i got the bad end of the deal on my motor build using crap somg heads and rpm cam

. Well I was planning on using some vortec heads upgraded for more lift with a comp xe262 cam and an air gap intake. Well I have been pondering the idea of a crate motor. To do the top end pakage im right at about 2500 bucks give or take a few this is using the stock bottom end with 4 valve reilfe pistons that have a lot of carbon build up for a rebuilt motor with less than 1000 miles on it. I fiqure for a few bucks more i can get a motor i know was built well and comes with a 2 year 12,000 mile warranty. Well I am looking at this crate motor from Derebery Performance. Here are the specs

350 ci 400 HP 430 TQ $2,995.00

-Balanced Dynamically
-9.5:1 Compression
-6000 RPM Limiter
-Hyperutectic Coated Pistons
-Hyd, Roller Camshaft 218/228 @.050 with .502/.502 lift
-Vortec Hand Ported Cylinder Heads
-Dual Plane Air Gap Intake Manifold
Idle

So my thing is would you go for the crate motor or just do the top end and cam swap on my current motor that was built by bubba.

Thanks in advance for the help.

Check out www.enginefactory.com . I had them build a great motor for me. They will work with you to get exactly what you want. They built a nice 350 at about 420 HP for me at a great price.

well i emailed them and this is what they sent me.

The Engine comes with a chrome oil pan, timing cover, valve covers and polished intake. The stock converter would be fine, but I would base an upgrade on what you plan to use the car for. The dyno sheet is attached. We do have carburetor and ignition options available.
