I have done a lot of research and spent alot of time, but this is going to be it for my new motor setup from http://www.enginefactory.com/.
Basically it will be all new 4 bolt block, with edelbrock e-tec 200 heads, rpm air gap vortec intake, comp cams 8-503-8 extreme energy hyd. roller cam http://www.compcams.com/Technical/Ca.../128-169.html. Edelbrock alum water pump. That will be one part. The other stuff will be holley 670 tbi from howell efi, (which I already have), adapter for tbi, and custom prom from howell. The reason I like howell is they make all the products for the fuel delivery, and will work with you to customize your chip. plus they program the chip to the holley unit that they supply. i will be getting new headers, coated, but not sure which ones yet. Plus I plan on either cowl hood or the big block style hood from ascd.. i think this will be a killer set up. I already have 2000 stall converter, eaton posi and 3.73.'s. Already installed ac delete box from iroczdave. Looks nice. plus the motors already out ans I am just cleaning and getting prepared. Should have everything completed by end of January.

Exactly which engine setup on that site are you referring to? Also, don't those engine combos on that site come complete with a carb and all?

They will build you whatever you want. I have spoken several times to the staff, and also viewed their video that they send out.

Sounds good to me man, I hope that howell chip works well for you. Let us know when you get it done and when you get times. Good Luck.
