You will actually have more hp with the vortec engine, 300+ with a four barrel and headers.
You have to run an electric fuel pump, vortec intake and weighted flexplate that fits the one piece rear main seal crank. Most cars on the road today have an electric fuel pump so it's not a big thing to me. I run the Summit brand intake which was around $150 and I believe I gave around $80 for my flexplate but you can get one cheaper.
You get a lot for your money though, vortec heads, hydraulic roller cam, 9.4:1 compression, balancer,not to mention it's a brand new motor not a rebuild.

I have a pair of vortec heads and valve covers my neighbor gave me, I don't remember if there was anything wrong with them at this point. I'm thinking they were okay and that it was a piston/block issue but I may need to check the valves. Definitely give me some things to start looking at.
Looks like I posted in the wrong forum, I don't know where it ended up because I thought I posted in general discussion. Oops! Sorrry...
