For the cost of the parts - why not get a vortec 4200 out of a Saab 9-7? The 2008 engines were 291 HP STOCK. Build a header and do some exhaust port work and you will have a 325HP engine.
Or add a turbo and get 400+ HP easy...
Still have not seen an invoice of what your build cost.
Always suggesting a 4200, which is fine, but not seeing what your build costs? What are you hiding, asked you before what your build cost w/no response.
It's not cheap
