sweet thanks street.

 

but u did say that with all those mods we are talking about i'll be at about 400 hp right?

 

A 400 small block chevy, with the addition of a Holley Stealth Ram, 2.02 heads (worked over), custom camshaft, free flowing exhaust, and precision tuning, your looking at way over 400 rear wheel horsepower (translating to 500+ at the crank). Remember though, peak horsepower numbers mean very little. You'll want to maximize the power under the curve...

 

thats awsome, what size fuel injectors should i get? could you give me a part number from summit? that would work with the 400.

 

also, should i get 1 3/4 headers, or 1 7/8?

 

another thing, i heard 3 inch exhaust on an application like mine would actually make me loose bottom end torque because i decrease velocity to gain airflow, so would i be better off with 2.5 inch pipe?

 

You'll want to run around 30-lb./hr injectors. You can get away with 24-lbs, but I would highly recommend 30 (especially if you decide to go the blower route down the line, it'll save you the trouble of needing bigger injectors ahead of time). Look up part number: ACC-150830 on Summit Racing's website...

As far as headers go, 1 3/4's is fine. If your running a Y-Pipe, you'll definitely want to go with a 3" exhaust, especially with 400 cubic inches. As far as losing bottom end torque is concerned, yes, the torque will be raised slightly in the RPM band, but believe me, you won't even notice it... especially with the addition of a stall speed converter, for those running an automatic.

 

i was planning on running duals that exit in front of the rear tires on both sides, so should i go 2.5 or 3 inches?

 

and also, if it isnt to much trouble, on summit, whats the part number for the perfect stall speed converter/torque converter for my application. i hope im not to much of a pain, you just seem to know alot, so im looking up to you for this one.

 

If your planning on running duals, then 2 1/2 will be more than sufficient. You'll definitely want to run a pair of resonators in place of the traditional bulky muffler, as they provide more than enough clearance, and they sound great (IMO)...

The stall speed depends highly on the camshaft you select for your application. When I chose my stall speed for my LS1 (SSF-3500), I waited for it to be dyno'ed first, then chose the stall (it'd be wise to wait). I currently run a TCI stall on both my 454, and LS1, and have been using that particular brand for as long as I can remember...

 

im not good or much familiar with stall converters, so if i got it dynoe'd, how will i know what stall i would need?

 

as for mufflers, i would choose glass packs because they are like straight through, but i want it to have a rumble, or a certain sound to it, thats why im not gonna run straight pipes either.

 

is this a good torque converter, i dont got alot of money, so i'm tryin to watch what i spend.

The one thing you'll want to avoid when building, is the installation of brand new parts... with equipment having a good amount of mileage on them (although there are some things that need to be new). If your tranny is being completely rebuilt, by all means, go with a new stall speed converter. But if the tranny has 50+ thousand miles on it (but is in really good condition), I would seriously consider a used (but good) converter, if your on a budget...
People are upgrading all the time, and you'll more than likely come across a converter with less than ten thousand miles on it fitting your application. I would seriously recommend completing the engine build first, while worrying about your stall speed later on. If your wise in your camshaft selection, she'll idle great... even below 1000-RPM (which provides more than enough time to explore torque converter possibilities)...

 

sounds good, thanks.
