1) I have a few questions for you guys. What kind of HP numbers would you say a setup like this would run? I have had this setup in desktop dyno for a couple of years and I know what that program says it will do but I dont know if that's realistic. I put in 3 edelbrock crate engine before and the numbers came out of the program accurate to 5 percent, and I think that's pretty impressive.

**I found DD to be within 5 per cent with my 383 build. I think that is a reasonable assumption.

2) are 210 heads too big for this application? Im looking to peak HP at 6000, maybe 6500 and with the lift on this cam and the intake valve size of the heads, am I gonna shift before I really get the best out of this motor? DD shows peak hp with this setup being 6000 on the dot, with only a 2hp drop to 6500rpms.

**I would use their 195 Eliminator heads. Unless you are turning a lot of rpm, you don't need 210's, especially for a street driven car. You will lose low end torque with 210's. AFR's 195 Eliminators make awesome hp and torque.

3) The cam listed is a mechanical roller, but I do NOT want a mechanical street car. would it be possible to either just slap hydraulic lifters on this cam, or maybe have one made custom to allow for hydraulic lifters? I really dont know what the difference is in a real world build.

**Solid rollers are not meant for the street. And you cannot mix and match lifter types with cam types. I would go with a hydraulic roller cam instead. You do not have to have a special cam grind made. There are a lot of choices out there from numerous companies. For street friendliness, I would recommend staying between 230 and 235 degrees of duration.

4) I want either a 900cfm 4 bbl holley injection system, or if I can piece one together I'd like to buy a tpi system, sell the intake and injectors, buy a stealthram intake/fuel rail and some nice injectors and build a MPFI combination for this. what would be needed to do such a thing, and would the stock ECU at all be able to be tuned to handle this or would I need an aftermarket ECU, or would it just be better to buy an aftermarket harness/ecu system and then piece all the hardware and sensors together for the MPFI system?

**A TPI will not handle the air needed for a 383 to breathe. Both Edelbrock and Holley sell similar injection systems. But there is a new kid on the block that I am very interested in. I would seriously consider this: www.fuelairspark.com/ezefi/default.asp

sorry for the long post and so many questions, but Im getting to a point where all of these things I've been thinking about for a while are finally gonna be coming together and I'd like to know what I need to expect to complete this build properly the first time.
