Help gentlemen (ladies too), I am putting together my first big block for a 69 Dart street car with a 727/8 3/4 (gear is TBD). RMS suspension is already installed In the interest of letting someone else do the trials and changes I am hoping to use the matched components in the following:

Trick Flow® PowerPort® Top-End Engine Kits for Big Block Mopar 440 TFS-K616-620-576

The motor will use a 512 stroker kit from 440 source in a '72 motorhome block. CR is planned to be 10.5 or close to it.

The #s they forecast from a smaller displacement block is here:

As I said I am looking for advice. I was born a poor white child who really needs to make the most of component choices. My brother is a die-hard Mopar guy but he has half a dozen small blocks laying around so I am stealing an RB out of his shed.

Please give me some thoughts to chew on.

Sounds like a heck of a deal to me . But I haven`t had good luck w/ hyd. roller lifters, too noisy for me. Don't know about trick flows tho. What are the cam specs , I didn`t see any ??
 
Trick Flow heads are great, I've been using them for almost two years now. I had one of the very first sets that they shipped. I think you are on the right track by building a 505. (If that block hasn't been bored out already then it will be a 505 on the first build). Use the 4.25 crank, 7.100 chevy rods and pick the correct pistons to give you 10.5 compression. Use the TF 240 heads and for the street a Performer RPM intake is probably a good choice or go with the Trick Flow intake for a little more racy look. I have not used the TF hyd roller cam but it should work just fine. That cam is 243/247 which will have some rumble to it even in a 505. If you don't know how to tune a carb you'll be asking for help. If you are more of a forward thinker then skip the carb and go straight to EFI. I'd recommend a Holley Sniper setup on that engine. Here is a video if you are interested of my 470 on the dyno with Trick Flow heads and a Holley Super Sniper:

You sound pretty sold in the Holley gear. I was planning FiTech or Edelbrock. Admittedly I have not looked into the Holley set up much. But I wii.

Thanks Andy

I am not the expert Andy is, but, I just pulled a cam out that is very similar to that one, except mine is a solid roller. It doesn`t have enough vacuum for my fuel inj. system. I`m having one ground "as we speak" ? , that has a wider lobe separation and is 6* smaller, lift about the same. I`m only supposed to lose 6 h.p. , but gain 4 ft pounds of torque , (like that is a big worry w/ a 505 !)
Your f.inj system may be diff., and be able to work w/ low vacuum, I don't have a clue, something to think about !

I run the FiTech system on mine, I pull about 5-6" of idle vacuum and it works flawlessly.

That is what I've been told and I was hoping to go that way. I am just looking to build a strong street car so I was really hoping to apply KISS principals.
