I poked around using search for a while and didn;t find the thread that answered this question, if i missed it sorry and point me to it please. So i am set to get a procharger installed on my car in the next month or so and i am thinking about the bottom end of the motor with all the guys blowing engines recently. Also I know some of you guys will say get a TS or another brand, but i am sold on the Procharger, one of the only local tuners has a great installed price and lots of expirence with the d1sc and i love the sound. At first on the stock bottom end things are going to be in the 450 rwhp range.

I have been planning to get the ford racing aluminator short block for boost later this year as an upgrade. From what I have been reading to keep things in a DD streetable range i am going to look at about 550 RWHP when all is said and done. I read a thread about making a streetable 650rwhp machine and that is just more loot than i want to throw at the car and from what i read on posts 550rwhp and a good clutch /flywheel and my factory manual SHOULD live a long and happy life if I don't drop the clutch at 5k daily. The question is this, at my HP goal will I really need to use aftermarket cams and get ported heads or can i put that money into the car elsewhere. If I can just go from teh 8-10 psi the procharger needs at 450whp to more boost and a better fuel system (GT500) I would rather do that, seems cheaper than 2K for heads and $1k for cams. Opinions? Right now I am thinking the FRPP aluminator, macloud rst and flywheel, and more boost along with GT500 fuel system for 550rwhp. That a good recipe?

Cool, i am also wondering if there woudl be a significant difference or any reason to sepnd the extra $1k and get teh livernoise 289 stroker SB rather than the FRPP one. Opinions?

I would keep the stock cams and have the heads ported or a new set of heads.

 

after doing a bunch of research on a similar topic, I would keep the stock block and drop in a rotating assembly and have your stock heads ported. Something like this http://www.haneymotorsport.com/HMS%2...ing%20Kits.htm and you will be good to go. Depending on how much of the labor you can do yourself, you can save some serious coin. Also, there a forum sponsor and if you ask them they will give you a discount.

 

I have a d1sc one thing I would suggest to you is to make sure you get the upgraded Procharger pulley that mounts to a ATI sfi balancer. I was running 11 psi and the standard procharger pulley that mounts to the stocked harmonic balancer loosened up and tore up the the keyway on the crank. When I called Procharger the Tech told me that I was probably pushing to much boost for the pulley system I bought which was a fine time to tell me now. So that is what made me start the build up of my engine. According to my builder the heads on the 3 valve flow so good all he recommended was a mild port. I did go with a set of cams that required new springs but no phasers mods. The main reason I went with a builder is so I could have it built like I wanted it and to have somebody to stand behind there work and not try to shift blame. I also went with Lethal Performance GT Triple Pump Fuel System. I should be back on the road in about 2 weeks hopefully pushing about 21 psi.
